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

View : 564
Type : E1 over IP
Description :

This device is mainly used for transmitting E1 signal over the IP network.


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.


Anode oxidation aluminum alloy shell, IP40 protection grade, can withstand the test of harsh environments;

Provide Console (CLI) and WEB management interface, easy for installation and open;

Provide 16 E1 ports, 2 10/100/1000M Ethernet electric interfaces, 1 100/1000M self-adaptive Ethernet SFP optical port;

Support several aim IP+ port settings, to realize the point to multi-point network, the remote end can be single E1 or 4E1 TDM over IP, and the total channel of E1 will not exceed 16;

E1 interface support 75Ω and 120Ω two types of interface, no need to set;

The clock recovery adopts unique clock calculation technology, with stable recovery frequency and small jitter and drift, which complies with the principle of G.823/G.824, 8261;

High transmission efficiency, low transmission delay; Ethernet packet length is available for setting, support long packet.; support VLAN setting;

Support E1 link loss packet indication function;

Support the host and remote side E1 loop function and the host E1 enable setting;

High transmission efficiency, is up to 90% bandwidth usage rate;

Support online updates of software and hardware of the host and remote device by WEB network management;

Optional power type :AC220V, DC-48V/DC24V etc.
