Multiservice Pseudowire Access Gateway

RAD’s Megaplex-1 is a compact, highly reliable multiservice access node that transports analog and TDM traffic originating from legacy circuit-switched devices, over packet switched networks (PSNs). 

Highly reliable delivery of TDM traffic over packet

The Megaplex-1 is specifically designed to address the needs of critical infrastructure network operators who are migrating to next-generation Ethernet or IP/MPLS communications. This includes utilities, transportation, and government users. It is specifically designed to address the needs of critical infrastructure network operators who are migrating to next-generation Ethernet, IP, or MPLS communications. It enables seamless service migration with a scalable TDM over packet pseudowire engine and comprehensive multiservice support for PDH, high and low-speed data, analog voice, and Teleprotection devices.
