Multiple T1/E1 Voice Circuits and LAN over Full or Fractional T1/E1 Links

Reduce network expenses by compressing T1/E1 voice circuits onto fractional/channelized T1/E1 links. All existing PBX features, such as voice mail, caller ID, Direct Station Select (DSS) and Busy Lamp Field (BLF), must be supported.

RAD’s Vmux product line utilizes TDMoIP (CV) technology to extend voice circuits (including signaling) transparently over IP or TDM networks and therefore eliminate the need for expensive T1/E1 voice circuits between enterprise offices. Transparent support for standard and proprietary signaling protocols, including ISDN PRI, Q.Sig, DPNSS and SS7, is important for the enterprise because it protects their investment in legacy PBXs and provides an evolutionary and simple means of supporting all phone features without expensive “forklift” upgrades. Business processes are not affected and there is no need to retrain users.

 

In this application TDMoIP (CV) performs voice compression and silence suppression before aggregating and multiplexing multiple voice channels onto fractional/channelized T1/E1 links. Integrated Ethernet switches and optional analog voice interfaces in the Vmux-110 voice trunking gateway for remote sites simplifies deployment at remote locations with a single box supporting all applications.

 · 16:1 compression reduces TDM bandwidth requirements · Any-to-any connectivity (P2P, P2MP, . .) · Fully transparent to signaling protocols to support voice, fax, modem, voice mail, CTI, DSS, and BLF
