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
