PMC-Sierra announced production of its new line of HDLC packet processors and high-density T1/E1 framers, which address highly channelized router, multi-service switching and wireless infrastructure applications. These fourth generation devices build upon PMC-Sierra’s multi-service switch line card solutions and enable scalable and flexible architectures in edge routers, multi-service provisioning platforms, and wireless radio network controllers and base station controllers.
PMC-Sierra said its new PM7310 FREEDM 336L, PM7311 FREEDM 84L and PM7312 FREEDM 32L devices are the industry’s first high-level data link control, Point-to Point Protocol (PPP), Frame Relay (FR), and Multilink-enabled packet processors to support a separate high priority path to interleave latency sensitive traffic, such as VoIP, with fragments of large data packets. The FREEDM 336L supports up to 336 T1 or 252 E1 links and is ideal for channelized OC-12/STM-4 line card designs. The FREEDM 84L supports up to 84 T1 or 63 E1 links and up to 1024 HDLC channels and is targeted at nxDS3 and nxOC-3/STM-1 line card designs. The FREEDM 32L supports up to 32 T1 or E1 links and up to 1024 HDLC channels and is ideal for multiple T1/E1 line card designs. http://www.pmc-sierra.com
