E1 TDM over IP (Ethernet) Converter | Desktop Type

The E1 TDM over IP converter is mainly used to transmit E1 signals on the IP network. It allows operators and enterprises to connect TDM equipment and user Ethernet on a standard low-cost wireless or wired Ethernet/IP structure without sacrificing quality.

This E1 TDM over IP converter is transparent to TDM signals and ensures the seamless connection of any equipment with a physical E1 interface, such as PBX, mobile base station, SS7 signaling equipment, and voice mail system. It can be used in IP-based communication systems, such as LAN, WAN, MAN, and wireless network.

The E1 TDM over IP converter has an E1 service port, 2 10/100/1000M Ethernet ports, a 100/1000M adaptive SFP optical port, and a console management interface.
