Communications: Single-Chip Controllers Facilitate Resilient-Packet-Ring Systems

The simplicity and bandwidth efficiency of Ethernet-based networks merge with the carrier-class features of Sonet/SDH infrastructure in the R-MAC family of resilient-packet-ring (RPR) media-access controllers (MACs). The single-chip R-MAC5 is a standards-compliant 5-Gbit/s RPR MAC that streamlines the integration of RPR into Sonet/SDH rings. It's the first MAC to offer channelization, allowing telecom providers to create virtual RPR rings over the same physical ring and use RPR technology as an overlay to existing Sonet/SDH-networks. R-MAC's built-in channelization and traffic-provisioning capabilities reduce capital and operations expenditures. Main applications include next-generation ADMs, MSPPs, MSTPs, Edge and Core Routers, Ethernet Aggregation Switches, and EPON Optical Line Terminations (OLTs). Contact the company for pricing.
