Product Overview

The PM8310 TEMUX 336 is a high density T1/E1, DS3/E3 framer, VT/TU  mapper, and M13 multiplexer with integrated SONET/SDH framers for  OC-12/STM-4 and 4xOC-3/STM-1 applications. Feature integration and  scalability make the TEMUX 336 ideal for use in ATCA/AMC line cards,  voice and media gateways, routers, and multi-service and edge aggregation switches. 

The TEMUX 336 device’s unique Extended Serial SONET/SDH Interface  (ESSI) enables: 

• A low pin-count interconnect to additional TEMUX 336 devices for  equipment protection applications  

• Higher-rate SONET/SDH framers such as the PM5336 ARROW 2488  for channelized OC-48/STM-16 designs 

• SONET/SDH cross-connects in transport applications 

• Ethernet over SONET/SDH mappers such as the PM4390  ARROW M8xFE 

Additionally, the device’s Scalable Bandwidth Interconnect (SBI) bus  enables a simple interconnect to PMC-Sierra Layer 2 solutions such as  the FREEDM (HDLC processor), S/UNI IMA (ATM inverse multiplexer)  and AAL1gator (ATM-based CES processor) families.

Product 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 CESbased PWE3 applications, by enabling independent timing for all  336/252 T1/E1s across the SBI using the V4 byte 

• Extended Serial SONET/SDH Interface (ESSI) can aggregate up to 4x  OC-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 336 device 

• Enables a scalable architecture from T1/E1 up to OC-12/STM-4 

• Supports T1/E1 mapping directly into SONET/SDH using VT1.5/TU-11  or VT2/TU-12 or multiplexed in 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
