Physical layer solution for high-bandwidth DS3/E3 deployment

13 March 2002 Telecoms, Datacoms, Wireless, IoT

PMC-Sierra's PM5383 S/UNI-12xJET is a complete physical layer solution for the aggregation, transport and termination of up to 12 channels of DS3/E3 and J2 protocols. It replaces up to four discrete devices, enabling cost-effective DS3 services to be deployed.

DS3/E3 is a widely used physical interface to connect metropolitan area network equipment. The S/UNI-12xJET is the industry's only single-chip solution for terminating packet/cell traffic for a single OC-12 down to the DS3/E3 level. Multimode operation allows single SONET and SDH transport line cards. It integrates 12 DS3/E3 mappers/framers, with corresponding desynchronisers and a STS-12 SONET/SDH framer, to support DS3/E3 mapping into SONET/SDH on a channel-by-channel basis. It is packaged in a 35 x 35 mm2, 580-pin TSBGA, rated for industrial temperature range.
