SAN JOSE, Calif. -- Corrigent Systems, a leading provider of packet transport solutions for next-generation transport networks, announced today that it has released TDM-to-Ethernet suite of interfaces for the CM-100 that enables carriers to easily aggregate Ethernet and other packet services from their existing TDM access networks. Using the CM-100, service providers can now offer popular Ethernet services over existing TDM access networks and aggregate these services efficiently on 10Gbps packet rings. This capability simplifies their networks, eliminates complicated interconnection equipment, lowers costs and creates the opportunity to quickly deliver Ethernet services using existing copper networks.

  • The following new interfaces are now available on the CM-100:

  • 24-port DS3/E3 clear-channel user interface module with Ethernet-over-PDH termination, as well as PPP to Ethernet Layer-2 interworking

  • PPP/MLPPP to Ethernet Layer-2 interworking on 6-port DS3/E3 channelized user interface module

Each of the modules also supports transport of native TDM channels, and the TDM-to-Ethernet interworking capability is configurable on a per-channel basis.

Service providers around the world deliver Ethernet and other data services over various access networks. TDM networks and circuits are used in most cases where fiber is not available to reach end customers. Ethernet E-Line, E-LAN, as well as access to Layer-3 VPN services are delivered in those cases over DS1/E1, bundled DS1/E1, orDS3/E3 circuits.

The Layer-2 interworking function on both DS3 interface types is designed to terminate PPP and/or bundled MLPPP sessions and map each individual connection to a standard Ethernet VLAN. Among the economic benefits this functionality will bring to service providers is the ability to replace channelized TDM interfaces to service terminating network elements, taking advantage of low cost Ethernet interfaces.These interfaces provide 1:1 and 1:N protection and support classification based on IP header priority bit information.

With these new capabilities, Corrigent's Packet Transport solution delivers savings that are unmatched by other available transport and aggregation solutions, and facilitates the migration to Ethernet-centric networks.
