The T1/ E1 to ethernet converter is a single port T1 or E1 with Ethernet Bridging that provides high-speed LAN-to-WAN connectivity.
Based on self-copyright IC.
Ethernet port 10/100M half/ full duplex self adaptable, supporting VLAN.
conforms to the requirements of G. 703, G. 704&G. 706 of ITU.
E1 can be either framed N*64Kbps (N=1-31) or unframed 2048Kbps
conforms to IEEE 802.3/ IEEE 802.3u and has VLAN 802.1Q function.
Support E1 line or T1 line;
E1 can support BNC 75-ohm and RJ45 120-ohm;
Support local and remote loops test, user can test circuitry and diagnose failure conveniently to achieve
port-to-port integrity test.
