o 1x STS-48/STM-16 2.488 GHz SONET/SDH Framed Interface. This is tied to one link
On the system side, provides redundant working and protect ingress and egress Serial
RASIO™ CML links. This interface is referred to as the System Ingress and Egress Serial
CML Interface in this document. These links are configurable as either:
o 8 x STS-12/STM-4 622.08 MHz SONET/SDH Framed Interfaces, or
o 8 x STS-12/STM-4 777.6 MHz 8B/10B Encoded TelecomBus Interfaces.
Independently configurable line and system interfaces. Line ingress and line egress
interfaces must be configured with the same type of interface as each other. Similarly,
system ingress and system egress interfaces must be configured with the same type of
interface as each other.
Provides capacity to carry an STS-12/STM-4 stream in each Serial RASIO™ CML link.
Four links can be aggregated to form an STS-48/STM-16 stream. Alternatively, on the line
side, one of the Serial RASIO™ CML links can carry an STS-48/STM-16 stream and the
other three links are unused.
Provides capacity to carry an STS-12/STM-4 stream in each 8-bit bus of the Byte-Wide
TelecomBus stream. Four 8-bit buses can be aggregated to carry an STS-48/STM-16
stream.
Provides optional PRBS (unframed PRBS or framed PRBS, STS-48c/VC-4-16c SPE for
2.488G links and STS-12c/VC-4-4c for 622M links) generation for each Line Egress and
System Ingress Serial RASIO™ CML stream for off-line link verification. Provides PRBS
monitoring for each Line Ingress and System Egress Serial RASIO™ CML stream for
off-line link verification.
Detects 8B/10B line code violations (LCVs) on the Serial RASIO™ CML 777.6 MHz
TelecomBus interfaces and accumulates them in internal registers.
Provides an inband communication channel in the system side RASIO™ CML links to
allow for centralized control and configuration when operating with a centralized fabric
(e.g. NSE).
Performs H1/H2 processing and generation to compensate for offsets in line ingress and line
egress J0(C1) frame alignment. Allows for separate ingress and egress J0(C1) frame
alignment via external frame alignment signals and programmable offsets.
On the line side 777.6 MHz links, provides encoding of TelecomBus control signals at the
multiplex section termination (MST) point and high-order path termination (HPT) point.
On the system side 777.6 MHz links, provides encoding of TelecomBus control signals at
the multiplex section termination (MST) point and high-order path termination (HPT) point.
and the other 3 links are unused.
Note: Refer to Table 6 for the difference between MST and HPT.
