Corrigent The Corrigent CM-4000 line of Packet Transport Switches (PTS) are packetbased
multiservice nodes that support the complete range, from 100% circuit traffic, to
100% packet traffic, all on the same device.
The CM-4000 provides efficient packet-based transport for all services including
Ethernet, Packet over SDH/SONET (PoS), Frame Relay, ATM and Fiber Channel with
full support for all TDM interfaces and SONET/SDH at all data rates. With a 160Gbps
or 320 Gbps switching capacity it supports Ring, Linear, and Mesh topologies and scales
up to 100Gbps thru link aggregation or ring bonding. It also has Layer 1 and Layer 2
interworking functions. The CM-4000 comes in two sizes, 14 and 6 I/O slot versions;
both are 19" ANSI and NEBs compliant.
The Corrigent PTS line was designed for data-centric applications and supports the
native transport of Ethernet frames and other data services as packets (without requiring
the mapping of Ethernet frames into TDM). When deployed in ring topologies, it
relies on RPR to create a lossless shared-media that allows for statistical multiplexing
of both data and TDM traffic over the same packet transport infrastructure.
