INFORMATION

TDMoverIP equipment is mainly used to provide 4 service card slots on the IP network, which can be inserted into E1 modules (4-way E1 interfaces), voice modules (4/8/16-way FOX/FXS

interfaces), V.35 modules (2-way V.35 interface), serial interface module (4-way RS232/422/485 interface); the maximum capacity can be filled with 4 slots. It allows operators and enterprises

to seamlessly and reliably connect TDM equipment and user Ethernet on a standard low-cost wireless or wired Ethernet/IP structure without any impact on voice quality. TDM over IP is

transparent to TDM signals, ensuring seamless connection of any equipment with physical E1 interface, such as PBX, mobile base station, SS7 signaling equipment and voice mail system.

Can be used in IP-based communication systems, such as: LAN, WAN, MAN and wireless networks. It has 4 E1 service ports, 2 100M Ethernet electrical ports, 1 100M Ethernet optical port,

and a Console management interface;
