Corrigent adds diagnostic, service management features to packet ADM platform

November 22, 2005 San Jose, CA -- Corrigent Systems announced the availability of new features in its CM-100 series of packet add-drop multiplexers (ADMs) for next-generation transport networks. The platform now offers testing, maintenance, and diagnostic capabilities designed to assist network operators with provisioning, maintaining, and troubleshooting networks.

According to the company, new maintenance and diagnostic capabilities now available with the CM-100 platform include: SONET/SDH line and path loopbacks on all SONET/SDH user interfaces, including low-order payload (VT) path loopback on Channelized OC-3/STM-1 modules; DS1/E1 and DS3 port and path loopbacks and test ports; an internal Pseudo Random Bit Stream (PRBS) test pattern generator and monitoring function on each user interface module per STS-n/VC-n path on all SONET/SDH user interface modules, and per VT on channelized SONET/SDH and DS1/E1 and DS3 user interface modules; Ethernet test packet generation and monitoring; Ethernet port-mirroring for non-intrusive traffic analysis in both ingress and egress directions; inter-module diagnostics and monitoring; VPLS redundancy and Remote Fault Indication (RFI) mechanism on Ethernet ports, for higher levels of service-level protection; and RPR OAM (Operations, Administration, Maintenance) functionality.

Corrigent says its CM-100 Packet ADM is an intelligent optical transport platform based on SONET/SDH, MPLS, RPR, and Ethernet technologies, that enables any combination of TDM and packet traffic in a single, converged 10-Gbit/sec packet transport device.
