TDM over IP (TDMoIP) technology, developed and pioneered by RAD, is an evolutionary approach for transporting circuit-switched telephony and legacy data (sync and async) over IP and Gigabit Ethernet networks.

TDMoIP transparently converts T1 or E1 circuits into IP packets for transmission over high performance IP-based backbones. It maintains all the features and functionality of today’s class 4 and 5 switches and SS7, PRI and other signaling protocols end-to-end across the network. The TDMoIP products deliver voice, fax, modem and data services over IP networks without compromising quality.
