16 Port E1 TDM over Ethernet (IP) Converter | Point to Multi-point

This device is mainly used for transmitting E1 signal over the IP network. It enables operators and enterprises to connect TDM devices and user Ethernet on a standard low-cost wireless or wired Ethernet/IP structure without any impact on quality. It is transparent to TDM signal, ensuring the seamless connection of any device with a physical E1 interface, such as PBXs, mobile base stations, SS7 signaling devices, and voicemail systems. It can be used in IP-based communication systems, such as LAN, WAN, MAN, and wireless networks.

It has 16 E1 service ports, 2 10/100/1000M Ethernet ports, 1 100/1000M self-adaptive optical port, and 1 console management port. The product can flexibly used with 4E1 or single E1 device, realizing E1 point to multipoint network.
