● Based on self-copyright IC
● Can realize monitor and control of remote equipment, OAM management data did not take up user’s timeslot and save E1 bandwidth
● E1 supports any timeslot set, the rate is 64K-2048K
● The local device can force the remote device rate to follow it
● Have an indicator when the remote device is power-off or the E1 line is broken or loses signal;
● Have the function of E1 interface loopback check, to avoid the converter crashing because of interface loop return;
● The Ethernet interface supports jumbo frames (2036 Bytes);
● Inter-set dynamic Ethernet MAC address (4,096) with local data frame filtering function
● Ethernet interface supports 10M/100M, half/full duplex auto- Negotiation, support VLAN
● Ethernet interface supports AUTO-MDIX (crossed line and straightly connected line self-adaptable );
● Have the Ethernet monitor self-reset function, the equipment will not dead
● Provide 2 clock types: E1 master clock and E1 line clock;
● Provide 2 impedances: 75 Ohm unbalance and 120 Ohm balance;
● Support SNMP Network Management
● Serial Data Interface can be RS232/RS422/RS485/TTL optional
● Serial channel can transmit adaptable serial data asynchronously at 300 Kbps-19200Kbps baud rate
● Serial data multiplexing in E1 support ITU-T R.111 jumping coding mode
● The local RS232 serial data can command the remote RS232 serial data loop back to the local. This loop- back in the outer ring of the RS232 data interface, you can test the RS232 interface chip without damage
● Serial port interface lightning-protection reached IEC61000-4-5 (8/20μS) DM(Differential Mode): 6KV, Impedance (2 Ohm),CM(Common Mode): 6KV, Impedance (2 Ohm) standard
