FEATURES
Fully integrated Solution for
OC-3/STM-1 and OC-12/STM-4
Add/Drop or Terminal Multiplexers
Capable of ring completion in a single
device (line protection mode) or as a
two-chip solution (full redundancy
mode)
Interfaces seamlessly with
PMC-Sierra's broad portfolio of
SONET/SDH transport devices
Integrated Cross-connect allows for
future system expansion and
incremental addition of transport
interfaces
SONET/SDH INTERFACE
Multi-rate SONET/SDH Interface
capable of operation at 155 or 622
Mbit/s
Integrated clock recovery allows direct
interface to low-cost optical
transceivers
Integrated clock synthesis generates
line clock from 77.76 MHz reference
Auxiliary telecombus interface allows
interface to alternate or secondary line
side framer
Complies with Bellcore, ANSI, and ITU
specifications for Jitter Tolerance,
Transfer, and Generation
High order path processing to
STS-1/AU-3/TU-3 level
Low order path processing to
VT1.5/VT2/TU-11/TU-12 level
Full access to all SONET/SDH
Overhead bytes
Integrated MAPS processing for fully
automatic UPSR path selection
LOW-ORDER / HIGH-ORDER
CROSS-CONNECT
Integrated 2.5G non-blocking memory
based cross-connect supports anycast
traffic
Support switching at STS/AU/VT/TU
level and all legal concatenations
Integrated MAPS processing for
automated protection switching
ADD/DROP PDH INTERFACES
