High Density T1/E1 Framer, VT/TU Mapper & M13
Mux with Integrated SONET/SDH Framers
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 multi-
plexers 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 inter-
connects 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
complete SONET/SDH front end with T1/E1, DS3/E3
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
CES-based PWE3 applications, by enabling independent timing
for all 168/128 T1/E1s across the SBI336 using the V4 byte
• Enables equipment protection in ACTA/AMC systems with its
extended Serial SONET/SDH Interface (ESSI) that can aggregate
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
Product Highlights
• 4 OC-3/STM-1 SONET/SDH framers (working and protection)
• 168 T1/126 E1 framers
• 6 M13 multiplexers, including support for G.747 multiplexing
• 6 DS3/E3 framers
• High order path processor for a SONET STS-3 or an SDH STM-1
• Tributary path processor for 168 VT1.5/TU-11s or 126 VT2/TU-12s
