PM5324 ARROW 1x192
SONET/SDH Transport Framer/Aggregator
for OC-48 and OC-192
•
Detects and inserts transport and path BIP-8 errors (B1, B2, B3).
Detects signal degrade (SD) and signal fail (SF) threshold crossing
alarms for B2 and B3
Provides overhead passthrough for entire TOH, and re-mapping for
B1, B2, M0/M1, and J0 bytes
Provides dedicated pins to extract and reinsert the entire transport
overhead
Provides dedicated pins to extract section and line DCC
Supports Automatic Protection Switching:
•
K1/K2 byte filtering and BER monitoring
•
Direct line card APS connections via system side APS ports
Supports centralized control of SONET/SDH processing by
providing in-band status messaging (Transport, Path, and
Equipment Status) on the ESSI ports
Provides independent STS-1 Memory Switching Units (MSU) for
combined time-slot interchange (TSI) and muxing functions in
transmit and receive directions
Provides independent STS-1 Memory Switching Units (MSU) at the
DROP APS port for grooming traffic to support line card pairing or
local traffic termination
Provides line loopback from the line side receive streams to the
transmit streams and supports diagnostic loopback on the system
side interface
•
SONET/SDH framer/aggregator for use in channelized
•
STS-192/STM-64 and STS-48/STM-16 applications
10 Gbit/s aggregate capacity. The framer can be configured to
support:
•
One STS-192/STS-192c / STM-64/STM-64c stream
•
Four STS-48/STS-48c / STM-16/STM-16c streams
Supports one STS-192/STM-64 stream via a standard OIF SFI-4
interface (duplex 16-bit 622 MHz LVDS) for direct connection to
SERDES and CRU/CSU devices
Supports up to four STS-48/STM-16 via SFI-4 interfaces operating
in nibble mode
Provides working, protect, and APS interfaces for connection
across system backplanes. Each interface consists of four ESSI
(Extended SONET Serial Interface) RASIO 3G links, operating at
2.488 Gbit/s
Supports channelized (down to STS-1), concatenated, and
arbitrarily concatenated (STS-3cxN) traffic. Changes in traffic
configurations are automatically detected
Terminates (or monitors) SONET/SDH Section, Line, and Path
overhead and provides STS-1 granularity frame alignment and
pointer processing
