GENERAL DESCRIPTION
The AMCC Rubicon-LH device is a wide-area and metropolitan
transport device aimed at next generation applications, required
transparent mapping, and enhanced error correction capability.
The device utilizes the ITU G.709 frame and overhead structures
to enable deployment of full OTN compliant network elements.
Rubicon-LH will support two gain rates, the standard G.975 based
rate of 6.2dB (raw optical coding gain), and AMCC’s proprietary
EFEC code, rated at greater than 8dB (raw optical coding gain).

CLIENT PERFORMANCE MONITORING
A SONET/SDH performance monitor supporting OC192/48/12/3
and SDH64/16/4/1 rates is provided to perform optional-section
and limited-line termination functions. TOH for the SONET signal
is dropped and added. On chip processing of the critical TOH
functions, such as B1, B2, J0, is provided to enable functioning as
a SONET/SDH network element. The performance monitor may
also be configured to provide non-intrusive monitoring while transparently passing through the received signal with no overwrite.
The 10 Gbps signal and the 2.5 Gbps signal may be synchronously or asynchronously mapped into the ODU-2 and ODU-1
payloads, respectively. FEC parity check bytes are then optionally
added to form the OTU-2 or OTU-1. The device can also output
the OTU-2 or OTU-1 with no parity check bytes. In the receive
direction, data is de-mapped from the OTU-2 or OTU-1 and control signals are provided to enable timing regeneration of the client
10 Gbps or 2.5 Gbps signal.
When operating in the ITU G.709 OTU-2/OTU-1 or ODU-2/ODU-1
mode, the SONET monitors can be bypassed. Unlike the Niagara
device, the Rubicon-LH provides the capability for intrusive
SONET/SDH performance monitoring inside the OTN frame. Onchip processing of the G.709 overhead is provided to enable single chip G.709 section termination. G.709 Overhead can be added
or dropped as required. The remapping that is required for synchronization of asynchronous ODU-1 signals is supported.
Client-signal monitoring for 8B/10B encoded data is also provided, as well as 64B/66B monitoring for 10GE-LAN traffic. A full
10GE-LAN MAC is also included in the Rubicon-LH device to support extensive 10GE monitoring.
10GE-LAN MAPPING
The Rubicon-LH device supports 2 distinct methods to map
10GE-LAN into OTU-2 for transport. The first is the same manner
as supported in the Niagara; that is, the line rate will run at 7%
above the client rate with the full 10GE-LAN being mapped into an
expanded OTU-2 frame. In this mode, the line rate of the Rubicon

of modes.
The second manner of 10GE-LAN mapping is supported in the
Rubicon-LH and involves the direct mapping of the client signal
into a 10.7GHz OTU-2 frame. There is no flow control to rate limit
the client in this mode.
AIS SUPPORT
For applications in which the client signal is SONET or SDH, the
Rubicon-LH can generate a SONET/SDH AIS on both the client
ingress and the egress.
For applications in which the client signal is G.709 compliant or for
OTN regenerator applications, Line Fail and un-equipped OTN
AIS is supported. For OTN edge applications, the device can be
provisioned to provide either a SONET/SDH AIS or a OTN
Generic AIS to the client. This facilitates convergence of the
SONET/SDH and OTN functions into a single network element.
ODU MAPPING
ITU compliant client mapping of SONET OC192 or SDH STM-64
into the ODU-2 signals (and the corresponding 2.5G signals into
an ODU-1) is supported whereby a stuff column is added to every
G.709 sub-frame resulting in an ODU rate expansion of (239/237).
The chip can be configured to insert the G.709 compliant stuff byte value or to insert user data into this column. The values
assigned to the stuff bytes can be defined either from a register
set on chip or from an external add-drop port. Coverage of these
stuff columns in the BIP calculation or in the FEC is optional and
can be enabled via software. When the no-coverage option is
enabled, the BIP and parity check values are calculated as if the
standard stuff values were present.
A direct map mode is supported for ODU-2 and ODU-1 with no
stuff columns to enable mapping with a 239/238 rate expansion.
Start-of-frame signals are provided at the input and output ports to
enable synchronization to the ODU.
LOOPBACK FUNCTIONS
Near-end and far-end loopback is supported for each of the client
interfaces and for the line interface. This enables line and device
testing and fault isolation. Each functional block may be bypassed
as required to support the application. When all blocks are
bypassed, the device allows transparent pass-through of client
data (assuming synchronous inputs).
FORWARD ERROR CORRECTION CAPABILITY
Two FEC options are supported on the 10 Gbps line side. The
Rubicon-LH can support standard RS(255,239) FEC compliant
with G.709, G.975, and compatible with the AMCC Hudson
device. The device can also support an enhanced FEC algorithm
that is applied using the same G.709 frame structure and data rate
as used in the Hudson and Niagara devices, but providing more
than 2 dB of additional coding gain (*measured at a BER of 1015
). The Rubicon-LH device will operate in a mode where both
encoders and decoders are working simultaneously, allowing for a
single chip transponder to operate between two networks with different gain characteristics.
LEGACY COMPATIBILITY
As indicated above, the Rubicon-LH also supports operation in
the G.975 mode. In this mode, the G.709 overhead processing
can be inhibited and direct access to the non-framing bytes in the
overhead column is provided through the pins on the device. The
device can should be configured to operate in the 255,238 mapping mode with no stuff columns inserted in the FEC payload.
FOOTPRINT COMPATIBILITY
In addition to the significant reuse of the Niagara register map in
the Rubicon, the Rubicon will also be pin compatible with the Niagara device. Although the core power balls will be driven to a
lower voltage (1.2V versus 1.8V), with careful board design considerations, the customer will be able to realize the Rubicon-LH
device in sockets designed for the Niagara chip. This capability
will allow the customer to use a more feature rich and lower power
dissipation device in the target socket.
CONTROL INTERFACE
A general purpose 16-bit microprocessor interface is provided for
control and monitoring. The interface supports both Intel and
Motorola type microprocessors, and is capable of operating in
either interrupt driven or polled-mode configurations.
Key status and alarm signals are provided to outside pins to
enable rapid response to failure conditions. These include but are
not limited to: LOS, OOF, LOF, B1 Errors, and FEC errors. Three
interrupt pins, each with a mask register are provided to enable
prioritization of interrupts and timely interaction with firmware.
In addition to the loopback capabilities of the device, the RubiconLH also employs a unique port swapping capability allowing the
physical ports on the device to be interfaced to either side of the
FEC encoders. With this capability a customer can use the EFEC
core on either physical port of the device. This capability
increases the flexibility of a single board design used in a variety
