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

View : 863
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 device can flexibly used with 4E1 or single E1 device, realizing E1 point to multipoint network.


The device features an anode oxidation aluminum alloy shell and an IP40 rating, it can withstand the test of harsh environments.

It provides Console (CLI) and WEB management interfaces.

It has 16 E1 ports, 2 10/100/1000M Ethernet ports,  and a 100/1000M self-adaptive Ethernet SFP optical port.

The E1 interfaces support 75Ω and 120Ω, 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 G.823/G.824, 8261.

It features high transmission efficiency and low transmission delay; Ethernet packet length is available for setting, which supports long packet and VLAN settings.

It supports the function of E1 link loss packet indication.

It supports the host and remote side E1 loop function and the host E1 enable setting.

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

It supports online updates of software of the host and remote device by WEB network management.

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