General information: This converter provide conversion from ITU-T G.703 E1 interface to 4 10/100Base-T Ethernet interface. used widely in connecting between WAN and LAN, monitoring, etc. Product characteristics: Based on self - copyright IC. Realize monitor of remote equipment from local equipment (having two row of LEDs, upper row indicate local status, lower row indicate remote status, unframing equipment does not have this function.) Ethernet interface Semi/full duplex self adapt, support VLAN. Ethernet interface support AUTO-MDIX. Provide 2 clock types: E1 master clock, E1 line clock. Provide 3 loop functions: local loop, to remote loop, order remote loop. Have pseudo random code test function, easy the installation and maintenance. E1 can support rate N*64k (N=1-32). Provide 2 impedances: 75 Ohm unbalance and 120 Ohm balance. Have Ethernet monitor self-reset function. Provide detecting realtime Ethernet communication status. Support 1-4 Ethernet switch function. Network manager use SNMP. Two types: Standalone, desktop, 19inch; Card, usually be inserted in 19 inch rack. E1 interface parameters: Interface standard according with G.703. Interface Rate n*64k, n 1/31. Jitter tolerance according with G.742 and G.823. Transmission capability 1*E1. Clock: inter-clock, line-clock. Connector BNC 75¦ё, RJ45 120¦ё. Interface Impedance BNC 75¦ё (unbalance), RJ45 120¦ё (balance).
10/100 Base - T interface parameters:
Interface rate 10/100Mbps. Duplex: half and full duplex self-adapt. Interface character match IEEE802.3, IEEE802.1Q (VLAN). Connector RJ45, support auto-mdix. MAC address capability 4096.
