EOIP TDM over Packet Circuit Simulator -Prefect E1 over IP transport solutions

Connecting traditional circuit-switched service as well as packet-switched data service over IP networks has become an attractive alternative to sufficiently using IP networks today. Efficiently combining TCP/IP technology together with TDM technology, TDM over IP circuit simulator - EOIP. It enables synchronous E1 signals delivered over broadband IP networks, takes the advantage of the low cost data transmission networks, seamlessly connects with all the traditional TDM terminals, that is, accommodates the traditional TDM services, such as PBX, modem, fax and video into IP networks.

 

EOIP guarantees the priority and quality of E1 traffic delivered over IP networks meanwhile using the rest bandwidth to transmit IP data traffic. It is well suited for offering telecom carriers an efficient and low cost E1 leased-line service, E1 circuit simulation over IP networks in microwave or satellite systems. It also can be used to interconnect phone systems of enterprises or schools.
