Pseudowire over Ethernet

With packet-switched networks (Ethernet, IP or MPLS) extending into the access, carriers and service providers will want to take advantage of Ethernet’s low Opex and Capex to deliver legacy services to the customer premises over packet-based transport.

RAD’s pseudowire access solutions enable carriers and service providers to deploy TDM, ATM, DSL, Frame Relay, and X.25 services as well as native Ethernet across packet-switched networks without loss of functionality or forklift upgrades to existing equipment or network infrastructure. Pseudowire provides seamless migration of a variety of legacy services to packet-switched networks, with full support for legacy equipment, including Class 4 and 5 switches, enterprise PBXs, TDM multiplexers, and PADs/FRADs.

Based on existing IETF, MFA Forum, ITU-T and MEF standards, RAD’s pseudowire over Ethernet/IP/MPLS solutions employ advanced clock recovery algorithms to deliver accurate clock synchronization across the PSN network, conforming to ITU-T G.823 jitter and wander requirements and ITU-T G.8261 timing and synchronization standards similar to those found in traditional TDM networks.
