8E1 TDM over Ethernet (IP) Converter

This device is mainly used for transmitting E1 signal over the IP network. It allows operators and enterprises to seamlessly and reliably connect TDM equipment and user Ethernet over a standardized, low-cost wireless or wired Ethernet/IP infrastructure, without any impact on voice quality.

TDM over IP is transparent to TDM signals, ensuring that any device with a physical E1 interface is seamlessly connected, such as PBX, mobile base stations, SS7 signaling devices, and voice mail systems. It can be used in IP-based communication systems such as LAN, WAN, MAN, and wireless networks.

This device features 8 E1 service ports, 2 10/100/1000M Ethernet ports, 1 100/1000M Ethernet optical port, and a console management interface.

● Arm cortex – M4 processor with main frequency of 192mhz is adopted;

● Anodized aluminum alloy shell, IP40 protection grade, can withstand the test of harsh environments;

● It provides console (CLI) and web management interfaces, making it easy to install and activate;

● It features 8 E1 ports, 2 10/100/1000M Ethernet ports, and 1 100/1000M adaptive Ethernet SFP optical port;

● E1 interface supports both 75 Ω and 120 Ω interfaces without setting;

● The device is capable of transparently transmitting both framed and unframed E1 (N*64K) signals over IP network, which is in compliance with the relevant G.703 standards;

● The clock recovery process employs unique clock algorithm technology, ensuring stable frequency restoration with low jitter and drift. Furthermore, the jitter and drift of the recovered clock comply with the recommendation of G.823/G.824 and G.8261;

●It offers high transmission efficiency and low transmission latency. Ethernet packet length can be configured, and jumbo frames are supported. Additionally, the device supports VLAN settings;

● It supports E1 link loss indication function;

● It supports local and remote E1 loopback functions, as well as local E1 enablement settings;

● It offers high transmission efficiency, with up to 90% bandwidth utilization efficiency;

● It supports online software and hardware upgrades for both local and remote devices via the web management interface;

● Multiple power supply modes are available: AC220V, DC-48v / DC24V, etc.
