TDM over IP (TDMoIP) is a transport technology that extends T1, E1, T3, E3, serial data or analog voice circuits transparently across IP or Ethernet networks. When used for voice, these TDMoIP circuits are transparent to signaling and provide superior voice quality with much lower latency* than VoIP. TDMoIP supports all PBX features and all modem and fax rates. TDMoIP, however, is not limited to voice and can extend circuits carrying ANY protocol over IP including Frame Relay, ATM, ISDN, SS7, SNA, HDLC, Async, Sync, X.25, as well as H.320 and H.324 video over IP. RAD deploys TDMoIP technology through the IPmux family of TDMoIP gateways.
