Product Description

1-port 10/100M Ethernet to E1 Bridge



MODEL7211A Series are cost effective Ethernet E1 network bridges that can implement Ethernet data transmission through E1 port. This series have 2 types of products and provides 1 100M Ethernet copper port and 1 E1 port, supports 220VAC or -48VDC. It adopts desktop mounting to meet the requirements of different scenes.


The DIP switch provides device impedance option, Ethernet port configuration, clock option, loopback test, etc. Hardware adopts fanless, low power consumption, wide temperature range design, and can be widely used to meet network requirements like extending and aggregating Ethernet in WAN or LAN and achieve interconnection and access of Ethernet device, thus solving the extending problem of Ethernet data.
