PMC-Sierra introduces 2.5 Gigabit device for grooming Ethernet-over-SONET/SDH, Frame Relay and voice traffic in metropolitan access networks

Dec. 16, 2002
December 16, 2002--PMC-Sierra introduced the PM5364 TUPPO 2488, an industry standard, tributary unit pointer processor and crossconnect for OC-48 (2.5 Gbits/sec) SONET and STM-16 (2.5 Gbits/sec) SDH networks.

PMC-Sierra introduced the PM5364 TUPPO 2488, an industry standard, tributary unit pointer processor and crossconnect for OC-48 (2.5 Gbits/sec) SONET and STM-16 (2.5 Gbits/sec) SDH networks.

The highly integrated TUPP 2488 performs grooming and cross-connection for widely deployed private lines carrying Ethernet, Frame Relay and voice services in metropolitan access networks. This new capability in access networks substantially reduces carrier costs by replacing high-power, multi-chassis, digital cross-connects in the network core with flexible, low-cost service card solutions in access networks. These new service cards can be deployed into existing add/drop multiplexers (ADMs), multiservice provisioning platforms (MSPPs), and STS-1/AU-4 optical crossconnects.

When adding new services to existing metro access equipment, such as Ethernet-over-SONET/SDH, a migration path is required to upgrade platforms while preserving existing investment. Tributary unit containers (VT/TUs) provide a common transport mechanism for traditional T1/E1 services and emerging data services such as Ethernet-over-SONET/SDH. The TUPP 2488 device enables 10/100 Mbits/sec Ethernet services to be groomed and cross-connected down to VT/TU granularity resulting in increased bandwidth utilization.

The TUPP 2488 substantially reduces customer premises, metro access ADM and MSPP costs and power consumption by integrating up to 13 devices previously needed for those solutions. While the metro core is built with OC-48/STM-16 networks, the metro access networks are predominately OC-3/STM-1 and OC-12/STM-4. The TUPP 2488 provides complete pointer processing, cross-connecting and line card fan-in for OC-3/STM-1 and OC-12/STM-4 transport solutions.

The OC-48/STM-16 device integrates pointer processing, payload alignment, a 2.5 Gbits/sec VT/TU crossconnect, performance monitoring, and 622 Mbits/sec and 2.5 Gbits/sec serial I/O technologies. For solutions requiring scalability beyond 2.5 Gbits/sec, the TUPP 2488 connects seamlessly to PMC-Sierra's NSE-20G or NSE-8G crossconnects for 20 Gigabit and 7.5 Gigabit capacities, respectively.

The PM5364 TUPP 2488 is a 1.8V CMOS device packaged in 35 mm by 35 mm, 580-pin UBGA package. The device is priced at $750 in 1KU quantities with samples available in January 2003. A comprehensive support package including reference design and application notes is available on PMC-Sierra's web site at http://www.pmc-sierra.com/products.
