PM8311 TEMUX 168

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:

• A low pin-count interconnect to additional TEMUX 168 devices
• SONET/SDH cross-connects in transport applications
• Ethernet over SONET/SDH mappers such as the PMC-Sierra PM4390 ARROW M8xFE

The device also includes the SBI bus, which enables simple intercon-nects with PMC-Sierra Layer 2 solutions.

The TEMUX 168 is fully hardware and software compatible with the TEMUX 336.
