PMC-Sierra Introduces Transmux and Mapping Solution to Reduce The Cost of Voice and Data Services; High Density TEMAP 168 Enables Carriers to Deploy the Lowest Cost Per Port Voice and Data Links in Existing and Next-Generation Transport Equipment.

SANTA CLARA, Calif. -- PMC-Sierra(TM), Inc. (Nasdaq:PMCS) today introduced the PM8318 TEMAP(TM) 168 device, the industry's highest density, trans-multiplexing (transmux) and PDH mapper solution. With the TEMAP 168, PMC-Sierra continues to expand its leadership in the transport equipment market, offering a highly integrated, low power solution that requires half the board space of other available competitive offerings (see: Figure 1). The device also integrates essential performance monitoring and messaging functions to reduce overall equipment operating costs by eliminating the need for separate test access and monitoring hardware.

"Due to the explosive growth in new voice and data connections, transmux has emerged as a key transport service to support interworking between legacy and next-generation networks," said Dino Bekis, vice president of marketing for PMC-Sierra's Communications Products Division. "TEMAP 168 is PMC-Sierra's third generation TEMAP device, bringing unsurpassed integration and functionality tailored to the transport market. This addition to our broad metro transport product portfolio enables equipment vendors and carriers to minimize time to market and improve operating and capital expenses in today's competitive environment."

TEMAP 168 Integrates Test Access to Reduce Operating Costs

The TEMAP 168 device supports standards compliant in-service performance monitoring and test access functionality for T1/E1, including the Facility Data Link protocol. Essential in any of today's T1/E1 transport systems, hardware-based performance monitoring and messaging functions in the TEMAP 168 greatly simplify transport equipment and overall network architectures by eliminating the need for separate test access and monitoring hardware (see: Figure 2).

By removing the need for an overlay test access infrastructure, and providing integrated test access functionality, the TEMAP 168 enables carriers to easily and efficiently manage Service Level Agreements and demarcation points remotely within the network, eliminating costly truck rolls.

Scalable, Cost-effective Transmux Services

Trans-multiplexing is the interworking between legacy and next-generation networks by bridging T1/E1 traffic mapped into legacy DS-3s to T1/E1 traffic mapped into standard SONET/SDH containers. The TEMAP 168 offers a highly integrated, flexible solution capable of supporting clear channel DS-3 and DS-3 transmux mapping on a single card, bringing substantial development cost savings to equipment vendors. Standard serial interfaces allow simple scaling of TEMAP 168 applications to OC-48/STM-16 or higher. The device integrates 168/126 T1/E1 bidirectional-PMON capable transceivers, six DS3/E3 bidirectional PMON-capable transceivers, and six M13 multiplexers (see: Figure 3).

Simple, Cost-effective Board Design and LIU Interfacing

As silicon geometries decrease and enable higher system densities, clock and data port interfaces can increase device pin counts, power consumption, and system cost. To eliminate these interface density constraints, the TEMAP 168 utilizes the Scalable Bandwidth Interconnect Transport (SBI TR) bus, an extension of the industry standard SBI(TM) bus. With a full suite of LIU solutions supporting the SBI TR bus, including the PM4329 HDLIU(TM) device, a 32 port T1/E1 device, TEMAP 168 is capable of achieving up to twice the physical density with lower capital and operating costs than any other solution on the market.

Availability and Customer Support

The PM8318 TEMAP 168 device is now sampling, packaged in a 23x23mm FCBGA and developed in 0.13 micron CMOS technology. The device integrates standard serial back-plane interfaces for seamless interworking with PMC-Sierra's extensive Metro Transport CHESS Family of devices. A new white paper on "T1/E1 Performance Monitoring" and a related paper on "Evolving Efficient Interconnects for High Density LIUs" are now available at www.pmc-sierra.com/pressroom/whitepapers.html.
