Product Overview

The PM8311 TEMUX 168 is a single device integrating 2xOC-3/STM-1 SONET/SDH framers for working and protect links, 168/126 T1/E1 framers, 6 DS3/E3 framers, 6 M13/G.747 multiplexers and 6 VT/TU mappers.

Designed for lower-density applications than its PM8310 TEMUX 336 counterpart, the TEMUX 168 device also interfaces seamlessly with a broad range of PMC-Sierra solutions. The TEMUX 168 includes the Extended Serial SONET/SDH interface (ESSI), enabling:

The device also includes the SBI bus, which enables simple interconnects with PMC-Sierra Layer 2 solutions and third-party network processors. The TEMUX 168 is fully hardware and software compatible with the TEMUX 336.

Benefits

• Meets ATCA/AMC space and power constraints with its framers/mappers/multiplexers on a single-chip
• Simplifies interconnection to layer 2 processors with an integrated SBI336 bus
• Meets timing requirements for wireless backhaul, critical for for all 168/128 T1/E1s across the SBI336 using the V4 byte
• Enables equipment protection in ACTA/AMC systems with its up to 2xOC-3/STM-1 on a single 4-wire interface
• Supports linear 1+1 protection on the same device or to a companion TEMUX 168
• Enables a scalable architecture from T1/E1 up to OC-12/STM4
• Supports T1/E1 mapping directly into SONET/SDH using V1.5/TU- 11 or VT2/TU-12 or multiplexed DS3s using M13 or G.747
• Supports advanced test features including programmable pattern generation and detection for up to 64 byte sequences
• Ensures reliability with a fully integrated, monolithic IC
