The PM8310 TEMUX-336 is a high density T1/E1 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 Microchip Layer 2 solutions such as the FREEDM (HDLC processor), S/UNI IMA (ATM inverse multiplexer) and AAL1gator (ATM-based CES processor) families. Benefits • Complete SONET/SDH front end with T1/E1, DS3/E3 ATCA/AMC space and power constraints • Integrated SBI bus simplifies interconnection to layer 2 processors • Meets timing requirements for wireless backhaul, critical for CESbased 336/252 T1/E1s across the SBI using the V4 byte • Extended Serial SONET/SDH Interface (ESSI) can aggregate up to 4x 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 Applications • ATCA/AMC-based line cards • Voice and media gateways • Wireless base station controllers (BSC) and radio network controllers (RNC) • Routers and multi-service switches • Edge aggregation switches • Multi-service provisioning platforms
