PM8311 TEMUX 168

High Density T1/E1 Framer, VT/TU Mapper & M13 Mux with

Integrated SONET/SDH Framers

Preliminary

Product Brief

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:

• 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.

BENEFITS

• Complete SONET/SDH front end with T1/E1, DS3/E3

framers/mappers/multiplexers on a single-chip that meets

ATCA/AMC space and power constraints.

• Integrated SBI bus simplifies interconnection to layer 2 processors

• Meets timing requirements for wireless backhaul, critical for CES-

based PWE3 applications, by enabling independent timing for all

168/128 T1/E1s across the SBI using the V4 byte

• Extended Serial SONET/SDH Interface (ESSI) can aggregate up to

2xOC-3/STM-1 on a single 4-wire interface, enabling equipment

protection in ACTA/AMC systems.

• 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

• Fully integrated, monolithic IC ensures reliability
