GENERAL DESCRIPTION
FEATURES
The XRT94L33 is a highly integrated SONET/SDH
terminator
designed
for
E3/DS3/STS-1
mapping/de-mapping functions from either the
STS-3 or STM-1 data stream. The XRT94L33
interfaces directly to the optical transceiver
•
Provides DS3/ E3 mapping/de-mapping for up to
3 tributaries through SONET STS-1 or SDH AU3 and/or TUG-3/AU-4 containers
•
Generates and terminates SONET/SDH section,
line and path layers
•
Integrated SERDES with Clock Recovery Circuit
•
Provides SONET
descrambling
•
Integrated Clock Synthesizer that generates 155
MHz and 77.76 MHz clock from an external
12.96/19.44/77.76 MHz reference clock
The XRT94L33 uses the internal E3/DS3 DeSynchronizer circuit with an internal pointer leak
algorithm for clock smoothing as well as to remove
the jitter due to mapping and pointer movements.
These De-Synchronizer circuits do not need any
external clock reference for its operation.
•
Integrated 3 E3/DS3/STS-1 De-Synchronizer
circuit that de-jitter gapped clock to meet
0.05UIpp jitter requirements
•
Access to Line or Section DCC
•
Level 2 Performance Monitoring for E3 and DS3
The SONET/SDH transmit blocks allow flexible
insertion of TOH and POH bytes through both
Hardware and Software. Individual POH bytes for
the transmitted SONET/SDH signal are mapped
either from the XRT94L33 memory map or from
external interface. A1, A2 framing pattern, C1 byte
and H1, H2 pointer byte are generated.
•
Supports mixing of STS-1E and DS3 or E3 and
DS3 tributaries
•
UTOPIA Level 2 interface for ATM or level 2P for
Packets
•
E3 and DS3 framers for both Transmit and
Receive directions
The SONET/SDH receive blocks receive SONET
STS-3 signal or SDH STM-1 signal and perform the
necessary transport and path overhead processing.
•
Complete
Transport/Section
Overhead
Processing and generation per Telcordia and
ITU standards
The XRT94L33 provides a line side APS
(Automatic Protection Switching) interface by
offering redundant receive serial interface to be
switched at the frame boundary.
•
Single PHY and Multi-PHY operations supported
•
Full line APS
applications
The XRT94L33 provides 3 Mappers for performing
STS-1/VC-3 to STS-1/DS3/E3 mapping function,
one for each STS-1/DS3/E3 framers.
•
Loopback support for both SONET/SDH as well
as E3/DS3/STS-1
•
Boundary scan capability with JTAG IEEE 1149
•
8-bit microprocessor interface
•
3.3 V ± 5% Power Supply; 5 V input signal
tolerance
APPLICATIONS
•
-40°C to +85°C Operating Temperature Range
•
Network switches
•
Available in a 504 Ball TBGA package
•
Add/Drop Multiplexer
•
W-DCS Digital Cross Connect Systems
The XRT94L33 processes the section, line and
path overhead in the SONET/SDH data stream and
also performs ATM and PPP PHY-layer
processing. The processing of path overhead bytes
within the STS-1s or TUG-3s includes 64 bytes for
storing the J1 bytes. Path overhead bytes can be
accessed through the microprocessor interface or
via serial interface.
A PRBS test pattern generation and detection is
implemented to measure the bit-error performance.
A general-purpose microprocessor interface is
included for control, configuration and monitoring.

Software Reset – SONET Block:
This READ/WRITE bit-field permits the user to command a software reset to
the SONET/SDH block. If the user invokes a software reset to the
SONET/SDH blocks then all of the internal state machines will be reset to
their default conditions; and each of the Receive STS-1/STS-3 TOH
Processor blocks will undergo a re-frame operation.
A “0” to “1” transition, within this bit-field commands this Software Reset.
Notes:
This Software Reset does not reset the command registers to
their default state. This can only be achieved by executing a
“Hardware RESET” (e.g., by pulling the RESET_L* input pin
“LOW”). This Software Reset does not affect the DS3/E3 Framer
blocks. The Software Reset bit-field, for the DS3/E3 Framer block
can be found in each of the 3 “DS3/E3 Operating Mode” registers
(Address Location= 0xNF00).

the “Receive STS-3 TOH Processor Block” for interrupt generation. If the
user writes a “0” to this register bit and disables the “Receive STS-3 TOH
Processor Block” (for interrupt generation), then all “Receive STS-3 TOH
Processor Block” interrupts will be disabled for interrupt generation. If the
user writes a “1” to this register bit, he/she will still need to enable the
individual “Receive STS-3 TOH Processor Block” interrupt(s) at the
“Source Level” in order to enable that particular interrupt.
0 – Disables all “Receive STS-3 TOH Processor Block” interrupts within
the device.
1 – Enables the “Receive STS-3 TOH Processor Block” at the “Block
Level” for interrupt generation.

DESCRIPTION
Loop-back Mode[3:0]
These four READ/WRITE bits-fields permit the user to configure the
XRT94L33 to operate in a variety of loop-back modes, as is tabulated
below.
Loop-back[3:0]
Resulting Loop-back Mode
0000
Normal Mode (e.g., No Loop-back Mode)
0001
Remote Line Loop-back:
In this mode, all data that is received by the
“Receive STS-3 TOH Processor” block will be
routed to the “Transmit STS-3 TOH Processor
block.
Note:
0010
If the user invokes this loop-back, then
he/she must configure the Transmit
STS-3/STM-1 circuitry to operate in the
Loop-timing mode by setting Bit 6
(STS-3 Loop-Timing Mode) within the
Receive
Line
Interface
Control
Register – Byte 1, to “1” (Address
Location: 0x0302).
Local Transport Loop-back:
In this mode, all data that is being output via the
“Transmit STS-3 TOH Processor” block will also
be internally routed to the “Receive STS-3 TOH
Processor” block.
NOTES:
0011
1.
If the user configures the XRT94L33
device to operate in the “Local
Transport Loop-back” Mode, then, in
addition to “routing” the Transmit Output
STS-3 data back into the “Receive
Path”, the Transmit Output STS-3 data
is still output via either the Transmit
STS-3 PECL Interface or the Transmit
STS-3 Telecom Bus Interface.
2.
The user must disable all “Automatic
Transmission of AIS-P/AIS indicator
upon Defects” features (within the chip)
in order to permit this loop-back to
function properly.

DESCRIPTION
STS-1 Telecom Bus – Sync Delay:
The Transmit STS-1 Telecom Bus is aligned to the “TxSBFP_in” input pin.
The user is expected to apply a pulse (with the period of a 6.48MHz clock
signal) at a rate of 8kHz to the “TxSBFP_in input (pin number G4). Each
Transmit STS-1 Telecom Bus will align its transmission of the very first
byte of a new STS-1 frame, with a pulse at this input pin.
These READ/WRITE bit-fields permit the user to specify the amount of
delay (in terms of 6.48MHz clock periods) that will exist between the rising
edge of “TxSBFP_in” and the transmission of the very first byte, within a
given STS-1 via the Transmit STS-1 Telecom Bus.
Setting this register to “0x00” configures each of the Transmit STS-1
Telecom Bus Interfaces to transmit the very first byte of a new STS-1
frame, upon detection of the rising edge of the “TxSBFP_in”.
Setting this register to “0x01” configures each of the Transmit STS-1
Telecom Bus Interfaces to delay its transmission of the very first byte of a
new STS-1 frame, by one 6.48MHz clock period, and so on.
Note:
This register is only active if at least one of the three STS-1
Telecom Bus Interfaces are enabled.

DESCRIPTION
STS-3 Telecom Bus – Sync Delay – Upper Byte:
The Transmit STS-3 TOH Processor block will generate the outbound
STS-3/STM-1 frames in alignment with the 8kHz pulse that is being
applied to the “TxSBFP_in” input pin.
The user is expected to apply a pulse (with the period of a 19.44MHz
clock signal) at a rate of 8kHz to the “TxSBFP_in input (pin number
G4).
The Transmit STS-3/STM-1 Telecom Bus will align its
transmission of the very first byte of a new STS-3/STM-1 frame, with a
pulse at this input pin.
These READ/WRITE bit-fields permit the user to specify the amount of
delay (in terms of 19.44MHz clock periods) that will exist between the
rising edge of “TxSBFP_in” and the transmission of the very first byte,
within a given STS-3 via the Transmit STS-3/STM-1 Telecom Bus.
Setting these two registers to “0x0000” configures each of the Transmit
STS-3/STM-1 Telecom Bus Interfaces to transmit the very first byte of a
new STS-3 frame, upon detection of the rising edge of the
“TxSBFP_in”.
Setting these register to “0x0001” configures each of the Transmit STS3 Telecom Bus Interfaces to delay its transmission of the very first byte
of a new STS-3 frame, by one 19.44MHz clock period, and so on.
Note:
This register is also active if the user has configured the
XRT94L33 device to transmit its outbound STS-3/STM-1 data
via the Transmit STS-3/STM-1 PECL Interface block. As a
consequence, the user can configure the XRT94L33 device
to align its transmission of STS-3/STM-1 frames (via the
Transmit STS-3/STM-1 PECL Interface) to the 8kHz signal
that is being applied to the “TxSBFP_in” input pin.

G4).
The Transmit STS-3/STM-1 Telecom Bus will align its
transmission of the very first byte of a new STS-3/STM-1 frame, with a
pulse at this input pin.
These READ/WRITE bit-fields (along with that within the “Interface
Control Register – Byte 3) permit the user to specify the amount of
delay (in terms of 19.44MHz clock periods) that will exist between the
rising edge of “TxSBFP_in” and the transmission of the very first byte,
within a given STS-3 via the Transmit STS-3/STM-1 Telecom Bus.
Setting this register to “0x0000” configures each of the Transmit STS3/STM-1 Telecom Bus Interfaces to transmit the very first byte of a new
STS-3 frame, upon detection of the rising edge of the “TxSBFP_in”.
Setting this register to “0x0001” configures each of the Transmit STS-3
Telecom Bus Interfaces to delay its transmission of the very first byte of

Note:
This register is also active if the user has configured the

DESCRIPTION
General Purpose Input/Output Pin # 7:
The exact function of this READ/WRITE bit-field depends upon whether the
“GPIO_7” pin is configured to be an input or an output pin.
If GPIO_7 is configured to be an input pin:
If GPIO_7 is configured to be an input pin, then this register bit operates as a
READ-ONLY bit-field that reflects the state of the “GPIO_7” (pin number
AA25) input pin.
If the “GPIO_7” input pin is pulled to a logic “HIGH”, then this register bit will be
set to “1”. Conversely, if the “GPIO_7” input pin is pulled to a logic “LOW”,
then this register bit will be set to “0”.
If GPIO_7 is configured to be an output pin:
If GPIO_7 is configured to be an output pin, then the user can control the logic
level of “GPIO_7” by writing the appropriate value into this bit-field.
Setting this bit-field to “0” causes the GPIO_7 output pin to be driven “LOW”.
Conversely, setting this bit-field to “1” causes the GPIO_7 output pin to be
driven “HIGH”.
Note:

If GPIO_6 is configured to be an input pin:
If GPIO_6 is configured to be an input pin, then this register bit operates as a
READ-ONLY bit-field that reflects the state of the “GPIO_6” (pin number W24)
input pin.
If the “GPIO_6” input pin is pulled to a logic “HIGH”, then this register bit will be
set to “1”. Conversely, if the “GPIO_6” input pin is pulled to a logic “LOW”,
then this register bit will be set to “0”.
If GPIO_6 is configured to be an output pin:
If GPIO_6 is configured to be an output pin, then the user can control the logic
level of “GPIO_6” by writing the appropriate value into this bit-field.
Setting this bit-field to “0” causes the GPIO_6 output pin to be driven “LOW”.
Conversely, setting this bit-field to “1” causes the GPIO_6 output pin to be
driven “HIGH”.

Rev222...000...000
This register bit-field is only active if STS-1 Telecom Bus – Channel 1
is enabled.
General Purpose Input/Output Pin # 2:
The exact function of this READ/WRITE bit-field depends upon whether the
“GPIO_2” pin is configured to be an input or an output pin.
If GPIO_2 is configured to be an input pin:
If GPIO_2 is configured to be an input pin, then this register bit operates as a
READ-ONLY bit-field that reflects the state of the “GPIO_2” (pin number V23)
input pin.
If the “GPIO_2” input pin is pulled to a logic “HIGH”, then this register bit will be
set to “1”. Conversely, if the “GPIO_2” input pin is pulled to a logic “LOW”,
then this register bit will be set to “0”.
If GPIO_2 is configured to be an output pin:
If GPIO_2 is configured to be an output pin, then the user can control the logic
level of “GPIO_2” by writing the appropriate value into this bit-field.
Setting this bit-field to “0” causes the GPIO_2 output pin to be driven “LOW”.
Conversely, setting this bit-field to “1” causes the GPIO_2 output pin to be
driven “HIGH”.

General Purpose Input/Output Pin # 1:
The exact function of this READ/WRITE bit-field depends upon whether the
“GPIO_1” pin is configured to be an input or an output pin.
If GPIO_1 is configured to be an input pin:
If GPIO_1 is configured to be an input pin, then this register bit operates as a
READ-ONLY bit-field that reflects the state of the “GPIO_1” (pin number
AC27) input pin.
If the “GPIO_1” input pin is pulled to a logic “HIGH”, then this register bit will be
set to “1”. Conversely, if the “GPIO_1” input pin is pulled to a logic “LOW”,
then this register bit will be set to “0”.
If GPIO_1 is configured to be an output pin:
If GPIO_1 is configured to be an output pin, then the user can control the logic
level of “GPIO_1” by writing the appropriate value into this bit-field.
Setting this bit-field to “0” causes the GPIO_1 output pin to be driven “LOW”.
Conversely, setting this bit-field to “1” causes the GPIO_1 output pin to be
driven “HIGH”.

General Purpose Input/Output Pin # 0:
The exact function of this READ/WRITE bit-field depends upon whether the
“GPIO_0” pin is configured to be an input or an output pin.
If GPIO_0 is configured to be an input pin:
If GPIO_0 is configured to be an input pin, then this register bit operates as a
READ-ONLY bit-field that reflects the state of the “GPIO_0” (pin number W25)
input pin.
If the “GPIO_0” input pin is pulled to a logic “HIGH”, then this register bit will be
set to “1”. Conversely, if the “GPIO_0” input pin is pulled to a logic “LOW”,
then this register bit will be set to “0”.

DESCRIPTION
Slow-Speed Ingress – Interface Port Enable:
This READ/WRITE bit-field permits the user to enable or disable the SSI
(Slow-Speed Ingress) Interface Port.
If the SSI Interface port is enabled, then it can be used to do either of the
following.
• To monitor (e.g., to drop out a replica of) the DS3, E3 or STS-1 signal,
that is traveling in the Ingress Direction DS3/E3 or Receive STS-1 path of
the “Selected” channel within the XRT94L33 device.
• To insert (e.g., to add-in) and overwrite the DS3, E3 or STS-1 signal, that
is traveling in the Ingress Direction DS3/E3 or Receive STS-1 path of the
“Selected” Channel within the XRT94L33 device.
0 – Disables the SSI Interface Port.
1 – Enables the SSI Interface Port.

R/W
Slow-Speed Ingress – Interface Port – Insert Direction:
This READ/WRITE bit-field permits the user to configure the SSI Interface
port to either monitor (e.g., extract) an “Ingress Direction DS3/E3” or
“Receive STS-1” signal, or to replace (e.g., insert) a DS3, E3 or STS-1
signal into the Ingress DS3/E3 or Receive STS-1 path of the “Selected”
channel.
If the user configures the SSI Interface port to monitor a given DS3, E3 or
STS-1 signal, then the SSI Interface will then be configured to be an “output”
interface. In this case, the SSI Interface port will consist of an “SSI_POS”,
“SSI_NEG” and “SSI_CLK” output signals. Additionally, a copy of the
Selected Ingress Direction DS3/E3 or Receive STS-1 signal will be output
via this output port.
If the user configures the SSI Interface port to replace (e.g., insert) an
“Ingress DS3/E3” or Receive STS-1 signal, then the SSI Interface will then
be configured to be an “input” interface. In this case, the SSI Interface port
will consist of an “SSI_POS”, “SSI_NEG” and “SSI_CLK” input signals.
Additionally, the DS3, E3 or STS-1 signal that is applied at this input port will
overwrite that of the selected “Ingress Direction DS3/E3” or the Receive
STS-1 signal.
0 – Configures the SSI Interface as an output port that will permit the user to
monitor the “selected” Ingress DS3/E3 or Receive STS-1 signal.
1 – Configures the SSI Interface as an input port. In this configuration, the
DS3, E3 or STS-1 signal that is input via this port will replace/overwrite the
“Ingress” DS3/E3 or Receive STS-1 signal, within the “selected” channel,
prior to being mapped into STS-3.
Note:
This bit-field will be ignored if the SSI Interface port is disabled.

Slow Speed Egress – Interface Port – Insert Direction:
This READ/WRITE bit-field permits the user to configure the SSE Interface
port to either monitor (e.g., extract) an “Egress Direction DS3/E3” or
“Transmit STS-1” signal, or to replace (e.g., insert) a DS3, E3 or STS-1
signal into the Egress Direction DS3/E3 or Transmit STS-1 path of the
“Selected” channel.
If the user configures the SSE Interface port to monitor a given DS3, E3 or
STS-1 signal, then the SSE Interface wil then be configured to be an
“output” interface. In this case, the SSE Interface port will consist of an
“SSE_POS”, “SSE_NEG” and “SSE_CLK” output signals. Additionally, a
copy of the Selected Egress Direction DS3/E3 or Transmit STS-1 signal will
be output via this output port.
If the user configures the SSE Interface port to replace (e.g., insert) an
“Egress DS3/E3” or Transmit STS-1 signal, then the SSE Interface will then
be configured to be an “input” interface. In this case, the SSE Interface port
will consist of an “SSE_POS”, “SSE_NEG” and “SSE_CLK” input signals.
Additionally, the DS3, E3 or STS-1 signal, that is applied at this input port
will overwrite that of the selected “Egress Direction DS3/E3” or the Transmit
STS-1 signal.
0 – Configures the SSE Interface as an output port that will permit the user
to monitor the “selected” Egress DS3/E3 or Transmit STS-1 signal..
1 – Configures the SSE Interface as an input port. In this configuration, the
DS3, E3 or STS-1 signal that is input via this port will replace/overwrite the
“Egress” DS3/E3 or Transmit STS-1 signal, within the “selected” channel,
prior to being mapped into STS-3.

STS-3 Loop Timing
Mode
R/W
DESCRIPTION
STS-3 Loop-Timing Mode:
This READ/WRITE bit-field permits the user to configure the 94L33 to
operate in the Loop-timing Mode. If the user implements this configuration,
then the following Transmit STS-3-related functional blocks will use the
“Recovered Clock” (Receive STS-3 timing) as its timing source.
• All three (3) Transmit SONET POH Processor blocks
• The Transmit STS-3c POH Processor block (if enabled)
• The Transmit STS-3 TOH Processor block
• The Transmit STS-3 PECL Interface block
• The Transmit STS-3 Telecom Bus Interface Block.
0 – Configures all of the Transmit STS-3 circuitry to operate in the “LocalTiming” Mode (e.g., the above-mentioned functional blocks will use the
Clock Synthesizer block as its timing source).
1 – Configures the Transmit STS-3 circuitry to operate in the “Loop-Timing”
Mode.

Split Loop Back
R/W
Split Loop-back Enable:
This READ/WRITE bit-field permits the user to configure the 94L33 to
operate in the “Split Loop-back” Mode. If the user implements this
configuration, then two types of loop-backs will exist within the chip
simultaneously.
a.
A Local Loop-back
This loop-back path will originate from the Transmit STS-3 TOH
Processor block. It will be routed through a portion of the “Transceiver
circuitry” (through the “Transmit Parallel-to-Serial Converter” block)
and then back to the “Receive Serial-to-Parallel Converter” block,
before being routed to the Receive STS-3 TOH Processor block.
b.
A Remote Loop-back
This loop-back path will originate from the Receive STS-3/STM-1
PECL Interface input. It will be routed through the CDR (Clock & Data
Recovery) block; before being routed to the Transmit STS-3/STM-1
PECL Interface output.
0 – Configures the 94L33 to NOT operate in the Split Loop-back Mode
1 – Configures the 94L33 to operate in the Split Loop-back Mode

This READ/WRITE bit-field permits the user to configure the 94L33 to
operate in the “Remote Serial Loop-back” Mode. In this mode, the
incoming (Received Data) will enter the device via the Receive STS3/STM-1 PECL Interface Input. This signal will then be processed via the
CDR (Clock and Data Recovery) Block. At this point, this input signal will
proceed via two paths in parallel. In one path, the signal will proceed onto
the “Receive Serial-to-Parallel” Converter and then the Receive STS-3
TOH Processor block (and so on). The other path will not proceed through
the “Receive Serial-to Parallel” Converter block. Instead this signal will
proceed on towards the “Transmit STS-3/STM-1 PECL Interface Output,
thereby completing the loop-back path.
0 – Configures the 94L33 to NOT operate in the Remote Serial Loop-back
Mode.

•
If the last (of the 3) A1 bytes, in the STS-3 data
stream is erred, or
•
If the first (of the 3) A2 bytes, in the STS-3 data
stream, is erred.
Hence, for this selection, a total of 16 bits are evaluated for
SEF defect declaration.

the SF defect condition.
NOTES:
o
The value that the user writes into these three (3)
“SF Set Monitor Window” registers specifies the duration
of the “SF Defect Declaration Monitoring Period”, in
terms of ms.

DESCRIPTION
SF_CLEAR_THRESHOLD – LSB:
These READ/WRITE bits, along the contents of the “Receive
STS-3 Transport – SF CLEAR Threshold – Byte 1” registers
permit the user to specify the upper limit for the number of B2
bit errors that will cause the Receive STS-3 TOH Processor
block to clear the SF (Signal Failure) defect condition.
When the Receive STS-3 TOH Processor block is checking
the incoming STS-3 signal in order to determine if it should
clear the SF defect condtiion, it will accumulate B2 byte errors
throughout the “SF Defect Clearance Monitoring Period”. If
the number of accumulated B2 byte errors is less than that
programmed into this and the “Receive STS-3 Transport SF
CLEAR Threshold – Byte 1” register, then the Receive STS-3
TOH Processor block will clear the SF defect condition.
NOTE: This particular register functions as the LSB (Least
Significant Byte) of the “16-bit” expression for the “SF Defect
Clearance B2 Byte Error” Threshold.

DESCRIPTION
SD_SET_MONITOR_INTERVAL – MSB:
These READ/WRITE bits, along the contents of the
“Receive STS-3 Transport – SD SET Monitor Interval –
Byte 1 and Byte 0” registers permit the user to specify
the length of the “monitoring period” (in terms of ms) for

When the Receive STS-3 TOH Processor block is
checking the incoming STS-3 signal, in order to
determine if it should declare the SD defect condition, it
will accumulate B2 byte errors throughout the userspecified “SD Defect Declaration monitoring period”. If,
during this “SD Defect Declaration Monitoring period”,
the Receive STS-3 TOH Processor block accumulates
more B2 byte errors than that specified within the
“Receive STS-3 Transport SD SET Threshold” register,
then the Receive STS-3 TOH Processor block will
declare the SD defect condition.
NOTES:

STS-3 TOH Processor block will then attempt to reacquire framing.
Writing a “1” into this bit-field configures the Receive STS-3 TOH Processor
block to declare the SEF defect condition. The Receive STS-3 TOH
Processor block will automatically set this bit-field to “0” once it has
reacquired framing (e.g., has detected two consecutive STS-3 frames with
the correct A1 and A2 bytes).

Receive Section Trace Message Buffer Read Selection:
This READ/WRITE bit-field permits the user to specify which of the following
Receive Section Trace Message buffer segments that the Microprocessor will
read out, whenever it reads out the contents of the Receive Section Trace
Message Buffer address space.
a.
The “Actual” Receive Section Trace Message Buffer. The “Actual”
Receive Section Trace Message Buffer contains the contents of the
most recently received (and accepted) Section Trace Message via
the incoming STS-3 data-stream.
b.
The “Expected” Receive Section Trace Message Buffer. The
“Expected” Receive Section Trace Message Buffer contains the
contents of the Section Trace Message that the user “expects” to
receive. The contents of this particular buffer is usually specified by
the user.
0 – Executing a READ operation to the Receive Section Trace Message
Buffer address space will return contents within the “Actual” Receive Section
Trace Message” buffer.
1 – Executing a READ operation to the Receive Section Trace Message
Buffer address space will return contents within the “Expected” Receive
Section Trace Message Buffer”.

Receive Section Trace Message Accept Threshold:
This READ/WRITE bit-field permits a user to select the number of consecutive
times that the Receive STS-3 TOH Processor block must receive a given
Section Trace Message, before it is accepted, as described below. Once a
given “Section Trace Message” has been accepted then it can be read out of
the “Actual Receive Section Trace Message” Buffer.
0 – Configures the Receive STS-3 TOH Processor block to accept the
incoming Section Trace Message after it has received it the third time in
succession.
1 – Configures the Receive STS-3 TOH Processor block to accept the
incoming Section Trace Message after it has received it the fifth time in
succession.

0 – Configures the Receive STS-3 TOH Processor block to expect the Section
Trace Message boundary to be denoted by a “Line Feed” character.
1 – Configures the Receive STS-3 TOH Processor block to expect the Section
Trace Message boundary to be denoted by the presence of a “1” in the MSB
(most significant bit) of the very first byte (within the incoming Section Trace
Message). In this case, all of the remaining bytes (within the incoming Section
Trace Message) will each have a “0” within their MSBs.

DESCRIPTION
SD_BURST_TOLERANCE – MSB:
These READ/WRITE bits, along with the contents of the
“Receive STS-3 Transport – SD BURST Tolerance – Byte 0”
registers permit the user to specify the maximum number of B2
bit errors that the Receive STS-3 TOH Processor block can
accumulate during a single Sub-Interval period (e.g., an STS-3
frame period), when determining whether or not to declare the
SD (Signal Degrade) defect condition.
Note:
172
The purpose of this feature is to permit the user to
provide some level of B2 byte error burst filtering,
when the Receive STS-3 TOH Processor block is
accumulating B2 byte errors in order to declare the SD
defect condition. The user can implement this feature
in order to configure the Receive STS-3 TOH
Processor block to detect B2 bit errors in multiple
“Sub-Interval” periods before it will declare the SD
defect condition.

DESCRIPTION
SD_CLEAR_MONITOR_INTERVAL – MSB:
These READ/WRITE bits, along with the contents of the
“Receive STS-3 Transport – SD Clear Monitor Interval – Byte
1 and Byte 0” registers permit the user to specify the length of
the “monitoring period” (in terms of ms) for SD (Signal
Degrade) defect clearance.
When the Receive STS-3 TOH Processor block is checking
the incoming STS-3 signal in order to determine if it should
clear the SD defect condition, it will accumulate B2 byte errors
throughout the user-specified “SD Defect Clearance”
Monitoring period.
If, during this “SD Defect Clearance
Monitoring” period, the Receive STS-3 TOH Processor block
accumulates less B2 byte errors than that programmed into
the “Receive STS-3 Transport SD Clear Threshold” register,
then the Receive STS-3 TOH Processor block will clear the
SD defect condition.
NOTES:
1.
The value that the user writes into these three (3) “SD
Clear Monitor Window” Registers, specifies the
duration of the “SD Defect Clearance Monitoring
Period”, in terms of ms.
2.
This particular register byte contains the “MSB” (Most
Significant Byte) value of the three registers that
specify the “SD Defect Clearance Monitoring” period.

DESCRIPTION
Transmit AIS-P (via Downstream STS-1s) upon declaration of the
LOS (Loss of Signal) defect condition/Transmit DS3 AIS (via
Downstream DS3s) upon declaration of the LOS Defect condition:
The exact function of this bit-field depends upon whether the XRT94L33
device has been configured to handle STS-1 or DS3 signals, on the “lowspeed” side of the chip, as described below.
For those channels that are configured to operate in the STS-1
Mode:
This READ/WRITE bit-field permits the user to configure all of the active
Transmit STS-1 POH Processor blocks (within the XRT94L33 device) to
automatically transmit the AIS-P (Path AIS) Indicator via the
“downstream” STS-1 signals, anytime (and for the duration that) the
Receive STS-3 TOH Processor block declares the LOS defect condition.
0 – Does not configure all “activated” Transmit STS-1 POH Processor
blocks to automatically transmit the AIS-P Indicator via the “downstream”
STS-1 signals, anytime the Receive STS-3 TOH Processor block
declares the LOS defect condition.
1 – Configures all “activated” Transmit STS-1POH Processor blocks to
automatically transmit the AIS-P Indicator via the “downstream” STS-1
signals, anytime (and for the duration that) the Receive STS-3 TOH
Processor block declares the LOS defect condition.
Note:
1. In the “long-run” the function of this bit-field is exactly the same as that
of Bit 1 (Transmit AIS-P Down-stream – Upon LOS), within the Receive
STS-3 Transport – Auto AIS Control Register (Address Location=
0x1163). The only difference is that this register bit will cause each of
the “downstream” Transmit STS-1 POH Processor blocks to
IMMEDIATELY begin to transmit the AIS-P condition whenever the
Receive STS-3 TOH Processor block declares the LOS defect. This will
permit the user to easily comply with the Telcordia GR-253-CORE
requirements of an NE transmitting the AIS-P indicator downstream
within 125us of the NE declaring the LOS defect.
2. In the case of Bit 1 (Transmit AIS-P Downstream – Upon LOS),
several SONET frame periods are required (after the Receive STS-3

IMMEDIATELY begin to transmit the AIS-P condition whenever the
Receive STS-3 TOH Processor block declares the SD defect. This will
permit the user to easily comply with the Telcordia GR-253-CORE
requirements of an NE transmitting the AIS-P indicator downstream
within 125us of the NE declaring the LOS defect.
2. In the case of Bit 1 (Transmit AIS-P Downstream – Upon LOF),
several SONET frame periods are required (after the Receive STS-3
TOH Processor block has declared the SD defect), before the Transmit
STS-1 POH Processor blocks will begin the process of transmitting the
AIS-P indicators.
3. In addition to setting this bit-field to “1”, the user must also set Bit 0
(Transmit AIS-P via Downstream STS-1s Enable) within this register, in
order enable this feature.
For those channels that are configured to operate in the DS3 Mode:
This READ/WRITE bit-field permits the user to configure all of the active
DS3/E3 Framer blocks (within the XRT94L33 device) to automatically
transmit the DS3 AIS indicator via the “downstream” (or Egress
Direction) DS3 signals, anytime (and for the duration that) the Receive
STS-3 TOH Processor block declares the SD defect condition.
0 – Does not configure all “active” DS3/E3 Framer block s to
automatically transmit the DS3 AIS indicator via the “downstream” DS3
signals, anytime the Receive STS-3 TOH Processor block declares the
SD defect condition.
1 – Configures all “active” DS3/E3 Framer blocks to automatically
transmit the DS3 AIS Indicator via the “downstream” DS3 signals,
anytime (and for the duration that) the Receive STS-3 TOH Processor
block declares the SD defect condition.
NOTE: In addition to setting this bit-field to “1” the user must also set Bit
0 (Transmit AIS-P/AIS via Downstream STS-1s/DS3s Enable) within this
register, in order to enable this feature.

device has been configured to handle STS-1 or DS3 signals, on the “lowspeed” side of the chip, as described below.
For those channels that are configured to operate in the STS-1
Mode:
This READ/WRITE bit-field permits the user to configure all of the active
Transmit STS-1 POH Processor blocks (within the XRT94L33 device) to
automatically transmit the AIS-P (Path AIS) Indicator via the
“downstream” STS-1 signals, anytime (and for the duration that) the
Receive STS-3 TOH Processor block declares the SF defect condition.
0 – Does not configures all “activated” Transmit STS-1 POH Processor
blocks to automatically transmit the AIS-P Indicator via the “downstream”
STS-1 signals, anytime the Receive STS-3 TOH Processor block
declares the SF defect condition.

the “downstream” Transmit STS-1 POH Processor blocks to
IMMEDIATELY begin transmit the AIS-P condition whenever the Receive
STS-3 TOH Processor block declares the SF defect. This will permit the
user to easily comply with the Telcordia GR-253-CORE requirements of

AIS-L Output Enable:
This READ/WRITE bit-field, along with Bits 7 (8kHz or STUFF Out
Enable) within the “Operation Output Control Register – Byte 1” (Address
Location= 0x0150) permit the user to configure the “AIS-L” indicator to be
output via the “LOF” output pin (pin AD11).
If Bit 7 (within the “Operation Output Control Register – Byte 1”) is set to
“0”, then setting this bit-field to “1” configures pin AD11 to function as the
AIS-L output indicator.
If Bit 7 (within the “Operation Output Control Register – Byte 1”) is set to
“0”, then setting this bit-field to “0” configures pin AD11 to function as the
LOF output indicator.
If Bit 7 (within the “Operation Output Control Register – Byte 1) is set to
“1”, then this register bit is ignored.

The register map for the Receive STS-3c POH Processor Block is presented in the Table below. Additionally,
a detailed description of each of the “Receive STS-3c POH Processor” block registers is presented below.
In order to provide some orientation for the reader, an illustration of the Functional Block Diagram for the
XRT94L33, with the “Receive STS-3c POH Processor Block “highlighted” is presented below in Figure 2.
It should be noted that for Mapper Aggregation Applications, the Receive STS-3c POH Processor block is
only active if the user has configured the XRT94L33 device to handle STS-3c data via STS-1 Telecom Bus
Interface # 1. The Receive STS-3c POH Processor block is also active if the user configures the XRT94L33
device to operate in the “ATM UNI” or “PPP Packet over STS-3c” Mode. For details on XRT94L33 device
operate in the ATM or PPP Mode, the user should consult the “XRT94L33 Register Map/Description for
ATM/PPP Applications” document.

Check (Pointer Adjustment) Stuff Select:
This READ/WRITE bit-field permits the user to enable/disable the SONET
standard recommendation that a pointer increment or decrement operation,
detected within 3 SONET frames of a previous pointer adjustment
operation (e.g., negative stuff, positive stuff) is ignored.
0 – Disables this SONET standard implementation. In this mode, all
pointer-adjustment operations that are detected will be accepted.
1 – Enables this “SONET standard” implementation. In this mode, all
pointer-adjustment operations that are detected within 3 SONET frame
periods of a previous pointer-adjustment operation will be ignored.

This READ/WRITE bit-field permits the user to configure the Receive STS3c POH Processor block to support either the “Single-Bit” or the
“Enhanced” RDI-P form of signaling, as described below.
0 – Configures the Receive STS-3c POH Processor block to support the
Single-Bit RDI-P. In this mode, the Receive STS-3c POH Processor block
will only monitor Bit 5, within the G1 byte (of incoming SPE data), in order
to declare and clear the RDI-P defect condition.
1 – Configures the Receive STS-3c POH Processor block to support the
Enhanced RDI-P (ERDI-P). In this mode, the Receive STS-3c POH
Processor block will monitor bits 5, 6 and 7, within the G1 byte, in order to
declare and clear the RDI-P defect condition.

Type
R/W
REI-P Error Type:
This READ/WRITE bit-field permits the user to specify how the “Receive
STS-3c POH Processor block will count (or tally) REI-P events, for
Performance Monitoring purposes. The user can configure the Receive
STS-3c POH Processor block to increment REI-P events on either a “perbit” or “per-frame” basis. If the user configures the Receive STS-3c POH
Processor block to increment REI-P events on a “per-bit” basis, then it will
increment the Receive STS-3c Path REI-P Error Count” register by the
value of the lower nibble within the G1 byte of the incoming STS-3c datastream.
If the user configure the Receive STS-3c POH Processor block to
increment REI-P events on a “per-frame” basis, then it will increment the
“Receive STS-3c Path – REI-P Error Count” register each time it receives
an STS-3c SPE, in which the lower-nibble of the G1 byte (bits 1 through 4)
are set to a “non-zero” value.
0 – Configures the Receive STS-3c POH Processor block to count or tally
REI-P events on a per-bit basis.

DESCRIPTION
Accepted RDI-P Value:
These READ-ONLY bit-fields contain the value of the most recently

THRESHOLD[3:0]
R/W
A given RDI-P value will be “accepted” by the Receive STS-3c
POH Processor block, if this RDI-P value has been consistently
received in “RDI-P THRESHOLD[3:0]” number of SONET frames.
RDI-P Threshold[3:0]:
These READ/WRITE bit-fields permit the user to defined the “RDI-P
Acceptance Threshold” for the Receive STS-3c POH Processor Block.
The “RDI-P Acceptance Threshold” is the number of consecutive SONET
frames, in which the Receive STS-3c POH Processor block must receive a
given RDI-P value, before it “accepts” or “validates” it.
The most recently “accepted” RDI-P value is written into the “RDI-P
ACCEPT[2:0]” bit-fields, within this register.

DESCRIPTION
Received “Filtered” C2 Byte Value:
These READ-ONLY bit-fields contain the value of the most recently
“accepted” C2 byte, via the Receive STS-3c POH Processor block.
The Receive STS-3c POH Processor block will “accept” a C2 byte value
(and load it into these bit-fields) if it has received a consistent C2 byte, in
five (5) consecutive SONET frames.
Note:
1. The Receive STS-3c POH Processor block uses this register, along the
“Receive STS-3c Path – Expected Path Label Value” Register, when
declaring or clearing the UNEQ-P and PLM-P defect conditions.
2. The Address Location of the Receive STS-3c Path – Expected Path
Label Value” Register is 0x1197

Expected C2 Byte Value:
These READ/WRITE bit-fields permits the user to specify the
C2 (Path Label Byte) value, that the Receive STS-3c POH
Processor block should expect when declaring or clearing the
UNEQ-P and PLM-P defect conditions.
If the contents of the “Received C2 Byte Value[7:0]” (see
“Receive STS-3c Path – Received Path Label Value” register)
matches the contents in these register, then the Receive STS3c POH will not declare any defect conditions.
NOTE: The Receive STS-3c POH Processor block uses this
register, along with the “Receive STS-3c Path – Receive Path
Label Value” Register (Address Location = 0x1196), when
declaring or clearing the UNEQ-P and PLM-P defect
conditions.

This READ/WRITE bit-field permits a user to specify which of the following
Receive Path Trace Message buffer segments that the Microprocessor will
read out, whenever it reads out the contents of the Receive Path Trace
Message Buffer.
a.
The “Actual” Receive Path Trace Message Buffer. The “Actual”
Receive Path Trace Message Buffer contains the contents of the
most recently received (and accepted) Path Trace Message via the
incoming STS-3c data-stream.
b.
The “Expected” Receive Path Trace Message Buffer.
The
“Expected” Receive Path Trace Message Buffer contains the
contents of the Path Trace Message that the user “expects” to
receive. The contents of this particular buffer are usually specified
by the user.
0 – Executing a READ to the Receive Path Trace Message Buffer, will return

R/W
REI-L (Line – Remote Error Indicator) Error Type:
This READ/WRITE bit-field permits the user to specify how the “Redundant
Receive STS-3 TOH Processor block will count (or tally) REI-L events, for
Performance Monitoring purposes. The user can configure the Redundant
Receive STS-3 TOH Processor block to increment REI-L events on either a
“per-bit” or “per-frame” basis. If the user configures the Redundant
Receive STS-3 TOH Processor block to increment REI-L events on a “perbit” basis, then it will increment the “Redundant Receive STS-3 Transport
REI-L Event Count” registers by the contents within the M1 byte of the
incoming STS-3 data-stream
If the user configures the Redundant Receive STS-3 TOH Processor block
to increment REI-L events on a “per-frame” basis, then it will increment the
“Redundant Receive STS-3 Transport REI-L Event Count” register each
time it receives an STS-3 frame, in which the M1 byte is set to a “non-zero”
value.
0 – Configures the Redundant Receive STS-3 TOH Processor block to
count or tally REI-L events on a per-bit basis.
1 – Configures the Redundant Receive STS-3 TOH Processor block to
count or tally REI-L events on a per-frame basis.

B2 Error Type:
This READ/WRITE bit-field permits the user to specify how the “Redundant
Receive STS-3 TOH Processor block will count (or tally) B2 byte errors, for
Performance Monitoring purposes. The user can configure the Redundant
Receive STS-3 TOH Processor block to increment B2 byte errors on either
a “per-bit” or “per-frame” basis. If the user configures the Redundant
Receive STS-3 TOH Processor block to increment B2 byte errors on a
“per-bit” basis, then it will increment the Redundant Receive STS-3
Transport - B2 Byte Error Count” register by the number of bits (within each
of the three B2 byte values) that is in error.
If the user configures the Redundant Receive STS-3 TOH Processor block
to increment B2 byte errors on a “per-frame” basis, then it will increment
the “Redundant Receive STS-3 Transport – B2 Byte Error Count” Register,
each time it receives an STS-3 frame that contains at least one erred B2
byte.
0 – Configures the Redundant Receive STS-3 TOH Processor block to
count B2 byte errors on a “per-bit” basis.
1 – Configures the Redundant Receive STS-3 TOH Processor block to
count B2 byte errors on a “per-frame” basis.

B1 Error Type
R/W
B1 Error Type:
This READ/WRITE bit-field permits the user to specify how the “Redundant
Receive STS-3 TOH Processor block will count (or tally) B1 byte errors, for
Performance Monitoring purposes. The user can configure the Redundant
Receive STS-3 TOH Processor block to increment B1 byte errors on either
a “per-bit” or “per-frame” basis. If the user configures the Redundant
Receive STS-3 TOH Processor block to increment B1 byte errors on a
“per-bit” basis, then it will increment the “Redundant Receive STS-3
Transport - B1 Byte Error Count” register by the number of bits (within the
B1 byte value) that is in error.
If the user configures the Redundant Receive STS-3 TOH Processor block
to increment B1 byte errors on a “per-frame” basis, then it will increment
the “Redundant Receive STS-3 Transport – B1 Byte Error Count” Register

DESCRIPTION
AIS-L Defect Declared:
This READ-ONLY bit-field indicates whether or not the Redundant Receive
STS-3 TOH Processor block is currently declaring the AIS-L (Line AIS)
defect condition within the incoming STS-3 data stream. The Redundant
Receive STS-3 TOH Processor block will declare the AIS-L defect condition
within the incoming STS-3 data-stream if bits 6, 7 and 8 (e.g., the Least
Significant Bits, within the K2 byte) are set to the value “[1, 1, 1]” for five
consecutive STS-3 frames.
0 – Indicates that the Redundant Receive STS-3 TOH Processor block is
NOT currently declaring the AIS-L defect condition.
1 – Indicates that the Redundant Receive STS-3 TOH Processor block is
currently declaring the AIS-L defect condition.

The relationship between the state of these bit-fields and the corresponding
SEF Defect Declaration Criteria are presented below.
FRPATOUT[1:0]
SEF Defect Declaration Criteria
00
The Redundant Receive STS-3 TOH Processor
block will declare the SEF defect condition if either
of the following conditions are true for four
consecutive SONET frame periods.
01
•
If the last (of the 3) A1 bytes, in the STS-3 data
stream is erred, or
•
If the first (of the 3) A2 bytes, in the STS-3 data
stream, is erred.
Hence, for this selection, a total of 16 bits are
evaluated for SEF defect declaration.
10
The Redundant Receive STS-3 TOH Processor
block will declare the SEF defect condition if either
of the following conditions are true for four
consecutive SONET frame periods.
•
If the last two (of the 3) A1 bytes, in the STS-3
data stream, are erred, or
•
If the first two (of the 3) A2 bytes, in the STS-3
data stream, are erred.
Hence, for this selection, a total of 32 bits are
evaluated for SEF defect declaration.
11
The Redundant Receive STS-3 TOH Processor
block will declare the SEF defect condition if either
of the following conditions are true for four
consecutive SONET frame periods.
•
If the last three (of the 3) A1 bytes, in the STS3 data stream, are erred, or
•
If the first three (of the 3) A2 bytes, in the STS3 data stream, are erred.
Hence, for this selection, a total of 48 bits are
evaluated for SEF defect declaration.

SF_SET_MONITOR_INTERVAL – MSB:
These READ/WRITE bits, along the contents of the “Redundant

Byte 0” registers permit the user to specify the length of the
“monitoring period” (in terms of ms) for SF (Signal Failure) Defect
Declaration.
When the Redundant Receive STS-3 TOH Processor block is
checking the incoming STS-3 signal in order to determine if it should
declare the SF defect condition, it will accumulate B2 byte errors
throughout the user-specified “SF Defect Declaration monitoring
period”. If, during this “SF Defect Declaration Monitoring Period”, the
Redundant Receive STS-3 TOH Processor block accumulates more
B2 byte errors than that specified within the “Redundant Receive
STS-3 Transport SF SET Threshold” register, then the Redundant
Receive STS-3 TOH Processor block will declare the SF defect
condition.
NOTES:
1.
The value that the user writes into these three (3) “SF Set
Monitor Window” registers, specifies the duration of the “SF
Defect Declaration Monitoring Period, in terms of ms.
2.
This particular register byte contains the “MSB” (most
significant byte) value of the three registers that specify the
“SF Defect Declaration Monitoring Period”.

DESCRIPTION
SF_CLEAR_THRESHOLD – LSB:
These READ/WRITE bits, along the contents of the
“Redundant Receive STS-3 Transport – SF CLEAR Threshold
– Byte 1” registers permit the user to specify the upper limit for
the number of B2 bit errors that will cause the Redundant
Receive STS-3 TOH Processor block to clear the SF (Signal
Failure) defect condition.
When the Redundant Receive STS-3 TOH Processor block is
checking the incoming STS-3 signal in order to determine if it
should clear the SF defect condition, it will accumulate B2 byte
errors throughout the “SF Defect Clearance Monitoring
Period”. If the number of accumulated B2 byte errors is less
than that programmed into this and the “Redundant Receive
STS-3 Transport SF CLEAR Threshold – Byte 1” register, then
the Redundant Receive STS-3 TOH Processor block will clear
the SF defect condition.

DESCRIPTION
SD_SET_MONITOR_INTERVAL – MSB:
These READ/WRITE bits, along the contents of the
“Redundant Receive STS-3 Transport – SF SET
Monitor Interval – Byte 1 and Byte 0” registers permit
the user to specify the length of the “monitoring period”
(in terms of ms) for SD (Signal Degrade) defect
declaration.
When the Redundant Receive STS-3 TOH Processor
block is checking the incoming STS-3 signal, in order to
determine if it should declare SD defect condition, it will
accumulate B2 byte errors throughout the userspecified “SD Defect Declaration monitoring period”. If,
during this “SD Defect Declaration Monitoring period”,
the Redundant Receive STS-3 TOH Processor block
accumulates more B2 byte errors than that specified
within the “Redundant Receive STS-3 Transport SD
SET Threshold” register, then the Redundant Receive
STS-3 TOH Processor block will declare the SD defect
condition.
NOTES:

1.
The value that the user writes into these three
(3) “SD Set Monitor Window” registers,
specifies the duration of the “SD Defect
Declaration Monitoring Period”, in terms of ms.
2.
This particular register byte contains the
“MSB” (Most Signficant Byte) value of the
three registers that specify the “SD Defect
Declaration Monitoring Period”.

1.
The value that the user writes into these three (3)
“SD Set Monitor Window” Registers, specifies
the duration of the “SD Defect Declaration”
Monitoring Period, in terms of ms.
2.
This particular register byte contains the “LSB”
(least significant byte) value of the three registers
that specify the “SD Defect Declaration
Monitoring period”.

SEF Force:
This READ/WRITE bit-field permits the user to force the Redundant
Receive STS-3 TOH Processor block to declare the SEF defect condition.
The Redundant Receive STS-3 TOH Processor block will then attempt to
reacquire framing.
Writing a “1” into this bit-field configures the Redundant Receive STS-3
TOH Processor block to declare the SEF defect. The Redundant Receive
STS-3 TOH Processor block will automatically set this bit-field to “0” once it
has reacquired framing (e.g., has detected two consecutive STS-3 frames
with the correct A1 and A2 bytes).

Note:
The purpose of this feature is to permit the user to provide some
level of B2 byte error burst filtering, when the Redundant Receive
STS-3 TOH Processor block is accumulating B2 byte errors in
order to declare the SD defect condition. The user can implement
this feature in order to configure the Redundant Receive STS-3
TOH Processor block to detect B2 bit errors in multiple “SubInterval” periods before it will declare the SD defect condition.

DESCRIPTION
SF_BURST_TOLERANCE – MSB:
These READ/WRITE bits, along with the contents of the “Redundant Receive
STS-3 Transport – SF BURST Tolerance – Byte 0” registers permit the user to
specify the maximum number of B2 bit errors that the Redundant Receive
STS-3 TOH Processor block can accumulate during a single Sub-Interval
period (e.g., an STS-3 frame period), when determining whether or not to
declare the SF (Signal Failure) defect condition.
Note:
The purpose of this feature is to permit the user to provide some level
of B2 byte error burst filtering, when the Redundant Receive STS-3
TOH Processor block is accumulating B2 byte errors in order to
declare the SF defect condition. The user can implement this feature
in order to configure the Redundant Receive STS-3 TOH Processor
block to detect B2 bit errors in multiple “Sub-Interval” periods before
it will declare the SF defect condition.

When the Redundant Receive STS-3 TOH Processor
block is checking the incoming STS-3 signal in order to
determine if it should clear the SD defect condition, it
will accumulate B2 byte errors throughout the userspecified “SD Defect Clearance” Monitoring period. If,
during this “SD Defect Clearance Monitoring” period,
the Redundant Receive STS-3 TOH Processor block
accumulates less B2 byte errors than that programmed
into the “Redundant Receive STS-3 Transport SD
Clear Threshold” register, then the Redundant Receive
STS-3 TOH Processor block will clear the SD defect
condition.
NOTES:

DESCRIPTION
B1 Byte Error Mask[7:0]:
These READ/WRITE bit-fields permit the user to insert bit errors
into the B1 bytes, within the outbound STS-3 data stream.
The Transmit STS-3 TOH Processor block will perform an XOR
operation with the contents of the B1 byte (within each outbound
STS-3 frame), and the contents within this register. The results
of this calculation will be inserted into the B1 byte position within
the “outbound” STS-3 data stream. For each bit-field (within this
register) that is set to “1”, the corresponding bit, within the B1
byte will be in error.
Note:
323
For normal operation, the user should set this register
to 0x00.

DESCRIPTION
Transmit B2 Error Mask Byte:
These READ/WRITE bit-fields permit the user to specify exact
which bits, within the “selected” B2 byte (within the outbound
STS-3 signal) will be erred.
If the user configures the Transmit STS-3 TOH Processor block
to transmit one or more erred B2 bytes, then the Transmit STS-3
TOH Processor block will perform an XOR operation of the
contents of the B2 byte (within the “selected” STS-1 Channel)
and the contents of this register. The results of this calculation
will be written back into the “B2 byte” position within the
“selected” STS-1 Channel, (within the outbound STS-3 signal)
prior to transmission to the remote terminal.
The user can select which STS-1 channels (within the outbound
STS-3 signal) will contain the “erred” B2 byte, by writing the
appropriate data into the “Transmit STS-3 Transport – Transmit
B2 Byte Error Mask Register – Bytes 1 and 0 (Address
Location= 0x1927).
Note:
326
This bit-field is only valid if Bit 1 (B2 Error Insert), within

DESCRIPTION
E2 Pointer[3:0]:
These READ/WRITE bit-fields permit the user to uniquely identify one of
the 3 STS-1 E2 byte “shadow” registers, when performing read or write
operations to these registers.
If the user has set Bit 7 (Enable All STS-1s), within this register to “1”,
then the contents of these four register bits, act as a pointer to a given
“shadow” register. Once the user specifies this pointer value; then he/she
completes the read or write operation (to or from the “shadow” register) by
performing a read or write to the “Transmit STS-3 Transport – E2 Byte
Value” register (Address Location= 0x1947).
Valid “shadow” pointer values range from “0x00” to “0x02” (where the
pointer value of “0x00” corresponds to the E2 “shadow” register,
corresponding to STS-1 # 1; and so on).
Note:
This register bit is ignored if Bit 7 (Enable All STS-1s) is set to
“1”; or if Bit 5 (E2 Byte Insert Method) within the “Transmit STS3 Transport – SONET Transmit Control Register – Byte 1”
(Address Location= 0x1902) is set to “0”.

Transmit_E2_Byte_Value[7:0]
R/W
DESCRIPTION
Transmit E2 Byte Value:
The exact function of these register bits depends upon
whether Bit 7 (Enable All STS-1s) within the “Transmit STS-3
Transport – E2 Byte Control” Register (Address Location=
0x1944) has been set to “0” or “1”; as described below.
If “Enable All STS-1s” is set to “0”
If the appropriate “E2 Insert Method” is selected, then these
READ/WRITE bit-fields will permit the user to specify the
contents of the E2 byte, within the “outbound” STS-3 signal.
More specifically, this value will be loaded into the E2 byte
position, within STS-1 # 1 (within the outbound STS-3 signal).
If Bit 5 (E2 Insert Method) within the Transmit STS-3 Transport
– SONET Transmit Control Register – Byte 1 (Address
Location= 0x1902) is set to “1”, then the Transmit STS-3 TOH
Processor block will load the contents of this register into the
“E2” byte-field, within each outbound STS-3 frame.
If “Enable All STS-1s” is set to “1”
In this mode, these register bit permit the user to have direct
READ/WRITE access of the “STS-1 E2 Byte shadow” register;
that is being pointed at by the “E2 Pointer[1:0]” value.
These register bits are ignored if Bit 5 (E2 Byte Insert Method)
is set to “0”.

DESCRIPTION
Transmit J0 Byte Value[7:0]:
If the user has configured the Transmit STS-3 TOH Processor
block to use the “Transmit J0 Byte Value” Register as the “source”
of the “outbound” Section Trace Message, then these
READ/WRITE bits will permit the user to specify the contents
within the J0 byte of each outbound STS-3 frame.
Note:
336
This register is only valid if the Transmit STS-3 TOH
Processor block is configured to read out the contents
from this register and insert it into the J0 byte-field within
each outbound STS-3 frame. The user accomplishes
this by setting the “Transmit Section Trace Message
Source[1:0]” bit-fields (within the Transmit STS-3
Transport – Transmit Section Trace Message Control
Register – Address = 0x194F) to “1, 0”..

DESCRIPTION
Transmit J1 Byte Value:
These READ/WRITE bit-fields permit the user to have software control over
the value of the J1 byte, within each outbound STS-3c SPE.
If the user configures the Transmit STS-3c POH Processor block to this

byte within each “outbound” STS-3c SPE, prior to transmission to the
Transmit STS-3 TOH Processor block.
The Transmit STS-3c POH Processor block will perform an XOR
operation with the contents of this register, and its “locally-computed” B3
byte value. The results of this operation will be written back into the B3
byte-position within each “outbound” STS-3c SPE.
If the user sets a particular bit-field, within this register, to “1”, then that
corresponding bit, within the “outbound” B3 byte will be in error.
Note:
For normal operation, the user should set this register to 0x00.

DESCRIPTION
Transmit C2 Byte Value:
These READ/WRITE bit-fields permit the user to have software control over
the value of the C2 byte, within each outbound STS-3c SPE.
If the user configures the Transmit STS-3c POH Processor block to this
register as the source of the C2 byte, then it will automatically write the
contents of this register into the C2 byte location, within each “outbound”
STS-3c SPE.
This feature is enabled whenever the user writes a “0” into Bit 2 (C2 Byte
Insertion Type) within the “Transmit STS-3c Path – SONET Control Register
– Byte 0” register.
Note:
The Address Location of the Transmit STS-3c Path – SONET

DESCRIPTION
Pointer Force:
This READ/WRITE bit-field permits the user to load the values contained
within the “Transmit STS-3c POH Arbitrary H1 Pointer Byte” and “Transmit
STS-3c POH Arbitrary H2 Pointer Byte” registers into the H1 and H2 bytes
(within the outbound STS-3c data stream).
Note:
The actual location of the SPE will NOT be adjusted, per the value of
H1 and H2 bytes. Hence, this feature should cause the remote
terminal to declare an “Invalid Pointer” condition.
0 – Configures the Transmit STS-3c POH and Transmit STS-3 TOH Processor
blocks to transmit STS-3c/STS-3 data with normal and correct H1 and H2
bytes.
1 – Configures the Transmit STS-3c POH and Transmit STS-3 TOH Processor
blocks to overwrite the values of the H1 and H2 bytes (in the outbound STS3c/STS-3 data-stream) with the values in the “Transmit STS-3c POH Arbitrary
H1 and H2 Pointer Byte” registers.
Note:
1. The Address Location of the Transmit STS-3c Arbitrary H1 Pointer Byte
register is 0x19BF
2. The Address Location of the Transmit STS-3c Arbitrary H2 Pointer Byte
register is 0x19C3

“Negative” or “NDF” event (via the “Insert Positive Stuff”, “Insert Negative
Stuff”, “Insert Continuous or Single NDF” options, via software command) if no
pointer adjustment (NDF or otherwise) has occurred during the last 3 SONET
frame periods.
0 – Disables this feature.
In this mode, the Transmit STS-3c POH and Transmit STS-3 TOH Processor
blocks will execute a “software-commanded” pointer adjustment event,
independent of whether a pointer adjustment event has occurred in the last 3
SONET frame periods.
1 – Enables this feature.
In this mode, the Transmit STS-3c POH and Transmit STS-3 TOH Processor

the outbound STS-3c/STS-3 data stream. This command, in-turn will cause a
“Pointer Decrementing” event at the remote terminal.
Writing a “0” to “1” transition into this bit-field causes the following to happen.
• A negative-stuff will occur (e.g., a single payload byte will be inserted into
the H3 byte position within the outbound STS-1/STS-3 data stream).
• The “D” bits, within the H1 and H2 bytes will be inverted (to denote a
“Decrementing” Pointer Adjustment event).
• The contents of the H1 and H2 bytes will be decremented by “1”, and will be
used as the new pointer from this point on.

Insert Positive Stuff:
This READ/WRITE bit-field permits the user to configure the Transmit STS-3c
POH and Transmit STS-3 TOH Processor blocks to insert a positive-stuff into
the outbound STS-3c/STS-3 data stream. This command, in-turn will cause a
“Pointer Incrementing” event at the remote terminal.
Writing a “0” to “1” transition into this bit-field causes the following to happen.
• A positive-stuff will occur (e.g., a single stuff-byte will be inserted into the
STS-3c/STS-3 data-stream, immediately after the H3 byte position within the
outbound STS-3c/STS-3 data stream).
• The “I” bits, within the H1 and H2 bytes will be inverted (to denote a
“Incrementing” Pointer Adjustment event).
• The contents of the H1 and H2 bytes will be incremented by “1”, and will be
used as the new pointer from this point on.

This READ/WRITE bit-field permits the user configure the Transmit STS-3c
POH and Transmit STS-3 TOH Processor blocks to continuously insert a New
Data Flag (NDF) pointer adjustment into the outbound STS-3c/STS-3 data
stream.
Note:
As the Transmit STS-3c POH and Transmit STS-3 TOH Processor
blocks insert the NDF event into the STS-1/STS-3 data stream, it will
proceed to load in the contents of the “Transmit STS-3c POH
Arbitrary H1 Pointer” and “Transmit STS-3c POH Arbitrary H2
Pointer” registers into the H1 and H2 bytes (within the outbound
STS-3c/STS-3 data stream).
0 – Configures the “Transmit STS-3c TOH and Transmit STS-3 POH
Processor” blocks to not continuously insert NDF events into the “outbound”
STS-3c/STS-3 data stream.
1- Configures the “Transmit STS-3c TOH and Transmit STS-3 POH

R/W
DESCRIPTION
DS3 AIS upon Async PDI-P or AIS-P:
This READ/WRITE bit-field permits the user to configure the Receive SONET
POH Processor block to automatically command the DS3/E3 Framer Block to
transmit the DS3 AIS indicator (to downstream circuitry) whenever (and for the
duration that) it (the Receive SONET POH Processor block) declares the Async
PDI-P or AIS-P defect condition within the incoming STS-1 SPE data-stream.
0 – Configures the Receive SONET POH Processor block to NOT automatically
command the DS3/E3 Framer block to automatically transmit the DS3 AIS
indicator (via the Egress Direction) upon declaration of either the AIS-P or the
Async PDI-P defect conditions.
1 – Configures the Receive SONET POH Processor block to automatically
command the DS3/E3 Framer block to automatically transmit the DS3 AIS
indicator whenever (and for the duration that) it declares either the AIS-P or the
PDI-P defect condition.
Note:
Note:
This register bit is only valid if the incoming STS-1 signal is
transporting an asynchronous DS3 signal; and if the corresponding
channel (on the “Low-Speed” Side of the chip) is configured to
operate in the DS3 Mode. Whenever an STS-1 signal is transporting
an asynchronously-mapped DS3 signal, then a given PTE will
recognize and declare the PDI-P defect condition whenever it
“accepts” the C2 byte to the value “0xFC”.

DESCRIPTION
Check (Pointer Adjustment) Stuff Select:
This READ/WRITE bit-field permits the user to enable/disable the SONET
standard recommendation that a pointer increment or decrement operation,
detected within 3 SONET frames of a previous pointer adjustment operation
(e.g., negative stuff, positive stuff) is ignored.
0 – Disables this SONET standard implementation. In this mode, all pointeradjustment operations that are detected will be accepted.
1 – Enables this “SONET standard” implementation. In this mode, all
pointer-adjustment operations that are detected within 3 SONET frame
periods of a previous pointer-adjustment operation, will be ignored.
2
RDI-P Type
R/W
Path – Remote Defect Indicator Type Select:
This READ/WRITE bit-field permits the user to configure the Receive SONET
POH Processor block to support either the “Single-Bit” or the “Enhanced”
RDI-P form of signaling, as described below.
0 – Configures the Receive SONET POH Processor block to support the
Single-Bit RDI-P. In this mode, the Receive SONET POH Processor block
will only monitor Bit 5, within the G1 byte (of incoming SPE data), in order to
declare and clear the RDI-P defect condition.
1 – Configures the Receive SONET POH Processor block to support the
Enhanced RDI-P (ERDI-P). In this mode, the Receive SONET POH
Processor block will monitor bits 5, 6 and 7, within the G1 byte, in order to
declare and clear the RDI-P defect condition.
1
REI-P Error
Type
R/W
REI-P Error Type:
This READ/WRITE bit-field permits the user to specify how the “Receive
SONET POH Processor block will count (or tally) REI-P events, for
Performance Monitoring purposes. The user can configure the Receive
SONET POH Processor block to increment REI-P events on either a “per-bit”
or “per-frame” basis.
If the user configures the Receive SONET POH
Processor block to increment REI-P events on a “per-bit” basis, then it will
increment the “Receive SONET Path REI-P Event Count” register by the
value of the lower nibble within the G1 byte of the incoming STS-1 datastream.
If the user configures the Receive SONET POH Processor block to
increment REI-P events on a “per-frame” basis, then it will increment the
“Receive SONET Path REI-P Event Count” Register each time it receives an
STS-1 frame, in which the lower nibble of the G1 byte (bits 1 through 4) are
set to a “non-zero” value.
0 – Configures the Receive SONET POH Processor block to count or tally
REI-P events on a per-bit basis.
1 – Configures the Receive SONET POH Processor block to count or tally

B3 Error Type:
This READ/WRITE bit-field permits the user to specify how the “Receive
SONET POH Processor block will count (or tally) B3 byte errors, for
Performance Monitoring purposes. The user can configure the Receive
SONET POH Processor block to increment B3 byte errors on either a “perbit” or “per-frame” basis. If the user configures the Receive SONET POH
Processor block to increment B3 byte errors on a “per-bit” basis, then it will
increment the “Receive SONET Path B3 Byte Error Count” register by the
number of bits (within the B3 byte value of the incoming STS-1 data-stream)
that is in error.
If the user configures the Receive SONET POH Processor block to
increment B3 byte errors on a “per-frame” basis, then it will increment the
“Receive SONET Path – B3 Byte Error Count” register each time it receives
an STS-1 SPE that contains an erred B3 byte.
0 – Configures the Receive SONET POH Processor block to count B3 byte
errors on a “per-bit” basis.
1 – Configures the Receive SONET POH Processor block to count B3 byte
errors on a “per-frame” basis.

DESCRIPTION
B3 Byte Error Count – (Bits 15 through 8):
This RESET-upon-READ register, along with “Receive SONET Path
– B3 Byte Error Count Register – Bytes 3, 2 and 0; function as a 32
bit counter, which is incremented anytime the Receive SONET POH
Processor block detects a B3 byte error.
Note:
1. If the Receive SONET POH Processor block is configured to count
B3 byte errors on a “per-bit” basis, then it will increment this 32 bit
counter by the number of bits, within the B3 byte (of each incoming
STS-1 SPE) that are in error.
2. If the Receive SONET POH Processor block is configured to count
B3 byte errors on a “per-frame” basis, then it will increment this 32 bit
counter each time that it receives an STS-1 SPE that contains an
erred B3 byte.

command the DS3/E3 Framer block to automatically transmit
an AIS signal upon detection of an AIS-P or PDI-P.
Note:
Note:
This register bit is only valid if the incoming STS-1 signal is
transporting an asynchronous DS3 signal; and if the
corresponding channel is configured to operate in the DS3
Mode. When an asynchronous DS3 signal is being
transported by a SONET signal, the PDI-P condition is
indicated by setting the C2 byte to the value “0xFC”.

This READ/WRITE bit field configures the corresponding DS3/E3 Framer
block to operate in the Framer Local Loop-back Mode. If the DS3/E3 Framer
block has been configured to operate in the Framer Local Loop-back Mode,
then the output of the Frame Generator block will be internally looped back
into the input of the Primary Frame Synchronizer block.

Internal LOS Enable:
This READ/WRITE bit-field permits the user to enable or disable the “Internal
LOS Detector”, within both the Primary and Secondary Frame Synchronizer
blocks. If the user enables the “Internal LOS Detector”, then the Primary
and/or Secondary Frame Synchronizer block will be configured to check the
incoming DS3/E3 signal for a sufficient number of “consecutive” all-zeros bits
and it will declare and clear the LOS defect condition based upon the “1s”
density and the number of consecutive “0” bits within the incoming DS3/E3
data-stream.
If the user disables the “Internal LOS Detector” then the Primary and/or
Secondary Frame Synchronizer block will NOT be configured to check the
incoming DS3/E3 signal for a sufficient number of “consecutive” 0 bits, and it

1.
The Internal LOS Detector can only be enabled if the
Channel is configured to operate in the Dual-Rail Mode. If
the Channel is configured to operate in the Single-Rail Mode,
then the Internal LOS Detector will be disabled.
2.
The Primary Frame Synchronizer block or the Secondary
Frame Synchronizer block (depending upon which block is
configured to operate in the Ingress Path) will automatically
declare the LOS defect condition anytime an off-chip LIU
device asserts the corresponding “EXT_LOS_n” input pin,
independent of the setting of this register bit.
Software RESET Input:
A “0” to “1” transition in this bit-field commands a Software RESET to each of
the following blocks within the Channel.
• The Primary Frame Synchronizer Block
• The Secondary Frame Synchronizer Block
• The Ingress Direction Mapper Block
• The Egress Direction Mapper Block
Once the user executes a Software reset to the Channel, all of the internal
state machines (within each of these blocks) will be reset; and the Primary
and Secondary Frame Synchronizer blocks will execute a “Reframe”
operation.

DESCRIPTION
Receive LAPD – Any kind:
This READ/WRITE bit-field permits the user to configure the Receive LAPD
Controller sub-block (within the Primary Frame Synchronizer block) to receive
any kind of LAPD Message (or HDLC Message) with a size of 82 bytes or less.
If the user implements this option, then the Receive LAPD Controller sub-block
will be capable of receiving any kind of HDLC Message (with any value of
header bytes). The only restriction is that the size of the HDLC Message must
not exceed 82 bytes.
0 – Does not invoke this “Any Kind of HDLC Message” feature. In this case, the
Receive LAPD Controller sub-block will only receive HDLC Messages that
contains the Bellcore GR-499-CORE values for SAPI and TEI.
Invokes this “Any Kind of HDLC Message” feature. In this case, the Receive
LAPD Controller sub-block will be able to receive HDLC Messages that contain
any header byte values.
Note:
This bit-field is ignored if the Primary Frame Synchronizer block is by-passed.
The user can determine the size (or byte-count) of the most recently received
LAPD/PMDL Message, by reading the contents of the “RxLAPD Byte Count”
Register (Address Location= 0xN384)

Receive LAPD – Any kind:
This READ/WRITE bit-field permits the user to configure the Receive LAPD
Controller sub-block to receive any kind of LAPD Message (or HDLC
Message) with a size of 82 bytes or less. If the user implements this option,
then the Receive LAPD Controller sub-block will be capable of receiving any
kind of HDLC Message (with any value of header bytes). The only restriction
is that the size of the HDLC Message must not exceed 82 bytes.
0 – Does not invoke this “Any Kind of HDLC Message” feature. In this case,
the Receive LAPD Controller sub-block will only receive HDLC Messages that
contains the Bellcore GR-499-CORE values for SAPI and TEI.
1 - Invokes this “Any Kind of HDLC Message” feature. In this case, the
Receive LAPD Controller sub-block will be able to receive HDLC Messages
that contain any header byte values.
Note:
This bit-field is ignored if the Primary Frame Synchronizer block is bypassed.
The user can determine the size (or byte count) of the most recently received
LAPD/PMDL Message, by reading the contents of the “Receive LAPD Byte
Count” Register (Address Location= 0xN384).

This READ/WRITE bit-field permits the user to configure the Receive LAPD
Controller sub-block (within the Primary Frame Synchronizer block) to receive
any kind of LAPD Message (or HDLC Message) with a size of 82 bytes or
less. If the user implements this option, then the Receive LAPD Controller
sub-block will be capable of receiving any kind of HDLC Message (with any
value of header bytes). The only restriction is that the size of the HDLC
Message must not exceed 82 bytes.
