SONET/SDH STS-192/STM-64 MUX/DEMUX with Pointer Processor
Overview and Applications
SONET Processing
The S19223 can be used in either SONET or SDH applications.
On the low-speed side, it can interface to 4 STS-48/STM-16 or 1
STS-192/STM-64 signal in each direction. On the high-speed
side, it can interface to 1 STS-192/STM-64 signal in each direction.
In the demultiplex direction, the S19223 accepts a 622 MHz 16-bit
STS-192/STM-64 signal. There are several modes of operation
that the S19223 supports in the demultiplex direction.
The S19223 provides a full bypass mode, as well as a pointer processor bypass mode. In the full bypass mode, the S19223 simply
passes the incoming STS-192/STM-64 signal directly through to
the Demux output. Framing, descrambling and TOH monitoring
are performed off-line, in a non-intrusive manner for monitoring
purposes only. No pointer processing, cross connection or frame
generation is performed.
In pointer processor bypass operation, the S19223 locates the
incoming STS-192/STM-64 frame, optionally descrambles the
data, and non-intrusively monitors the TOH. The STS-192/STM64 signal is then passed directly to the frame generation block, in
which outgoing TOH overhead bytes can be provisionally regenerated, on a per function basis. Again, no pointer processing is
performed, and the cross-connect block is bypassed.
For applications requiring pointer processing, the S19223 supports standard payload types STS-192c to STS-1 and Arbitrary
Concatenation payload types STS-6c/9c/24c, as well as their
SDH equivalent. The S19223 locates frame in the incoming STS192/STM-64 signal, performs descrambling, monitors the TOH
bytes, and then performs pointer processing. The pointer processor provides a mode in which the incoming TOH bytes transparently pass through the pointer processor to the corresponding
locations in the TOH of the outgoing tributaries. The TOH bytes
involved in this transparent pass-through mode include the
defined overhead bytes for the constituent STS-48/STM-16 or
STS-192/STM-64 signals. A 4xSTS-48/STM-16 mux, with inputs
from the MX and DX LINE and APS inputs, and a 192x192 crossconnect block is available after the pointer processor. This MUX/
cross-connect block can be used to select STS-1 from any of the
demuxed tributaries, tributaries from the low-speed mux inputs, or
tributaries from the DX and MX APS interfaces to place into any
one of the outgoing STS-1 time slots in any of the outgoing signals in the demux direction. Whether the signal contains an STS192c/AU-4-64c payload or a STS-192/AU-4-64 payload, the
S19223 can demultiplex the signal to 4 STS-48/STM-16 tributaries. The selected tributaries then proceed in the demux direction
to frame generators that provisionally generate the TOH/SOH
bytes, perform scrambling, and output the data. Alternatively, the
overhead data can be transparently passed through the from the
demux input to the demux output(s).
In the multiplex direction, the S19223 accepts a single 16-bit wide
622 MHz STS-192/STM-64 signal or 4 STS-48/STM-16 signals.
There are several modes of operation that the S19223 supports in
the multiplex direction.
For STS-192 only operation, the S19223 provides a full bypass

mode, as well as a pointer processor bypass mode. In the full
bypass mode, the S19223 simply passes the incoming STS-192/
STM-64 signal directly through to the mux output. Framing,
descrambling and TOH monitoring are performed off-line, in a
non-intrusive manner for monitoring purposes only. No pointer
processing, cross connection or frame generation is performed.
In pointer processor bypass operation, the S19223 locates the
incoming STS-192/STM-64 frame, optionally descrambles the
data, and non-intrusively monitors the TOH. The STS-192/STM64 signal is then passed directly to the frame generation block, in
which outgoing TOH overhead bytes can be provisionally regenerated, on a per function basis. Again, no pointer processing is
performed, and the cross-connect block is bypassed.
The S19223 also supports an Inverse Multiplexing mode, where
four incoming STS-48/STM-16 signals that are frequency locked
and framed aligned to each other, within 500 nsecs, can be interleaved to create an STS-192/STM-64 signal, and if required,
pointer processed.
For applications requiring pointer processing, the S19223 supports standard payload types STS-192c to STS-1 and Arbitrary
Concatenation payload types STS-6c/9c/24c, as well as their
SDH equivalent. The S19223 locates the incoming STS-192/
STM-64 or STS-48/STM-16, frames (from either the incoming
mux tributaries, or via the Deskew Buffers), descrambles the data,
non-intrusively monitors the TOH/SOH bytes and then performs
pointer processing for all valid combinations of STS-192C/AU-464c, STS-48c/AU-4-16c, STS-12c/AU-4-4c, STS-3c/AU-4-4c or
STS-1/AU-3 signals. The pointer processor also provides a mode
in which the incoming TOH bytes transparently pass through the
pointer processor to the corresponding locations in the TOH of the
outgoing tributaries. The TOH bytes involved in this transparent
pass-through mode include the defined overhead bytes for the
constituent STS-48/STM-16 or STS-192/STM-64 signals. A
4xSTS-48/STM-16 mux, with inputs from the MX and DX LINE
and APS inputs, and a 192x192 cross-connect block is available
after the pointer processor. This MUX/cross-connect block can be
used to select STS-1 from any of the incoming mux tributaries,
tributaries from the high-speed Pointer Processor outputs, or tributaries from the DX and MX APS interfaces to place into any one
of the outgoing STS-1 time slots in the outgoing STS-192/STM-64
signal in the mux direction. After the MUX/Cross-Connect block,
the STS-192/STM-16 muxed signal then proceeds to a frame
generator that provisionally generates the TOH/SOH bytes, performs scrambling, and outputs the data. Alternatively, the overhead data can be transparently passed through from the mux
inputs to output.
Low-Speed Interfaces
On the low-speed side, in both the mux and demux directions, the
S19223 supports either a 16-bit wide, 622 Mb/s STS-192/STM-64
signal, or four 4-bit wide, 622 Mb/s STS-48/STM-16 signals. The
S19223 is designed to bolt directly to AMCC SERDES and Clock
Recovery Unit devices. (See figure below.)
High-Speed Interface
On the high-speed side, in both the mux and demux directions,
the S19223 supports a 16-bit wide, 622 Mb/s STS-192/STM-64
signal.
