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 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.
