E1 TDM over IP (Ethernet) Converter | Desktop Type

The E1 TDM over IP converter is mainly used for transmitting E1 signals over the IP network. It allows operators and enterprises to connect TDM equipment and user Ethernet on a standard low-cost wireless or wired Ethernet/IP structure without sacrificing quality.

TDM over IP is transparent to TDM signals and ensures the seamless connection of any device with a physical E1 interface, such as PBX, mobile base station, SS7 signaling equipment, and voice mail system. It can be used in IP-based communication systems, such as LAN, WAN, MAN, and wireless networks.

The device has 1 E1 service port, 2 10/100/1000M Ethernet ports, 1 100/1000M adaptive SFP optical port, and a console management interface.

● Adopt arm cortex – M4 processor with a primary frequency of 192 MHz;

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

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

● The device features one E1 circuit, two 10/100/1000M Ethernet ports, and one 100/1000M Ethernet SFP optical port.

● The E1 interface supports both 75 Ω and 120 Ω without requiring any settings;

● 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 specifications of G.823/G.824 and G.8261;

● The device 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;

● Many power supply modes are available: AC220V, DC48V/DC24V, etc.
