? 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 forced the remote device rate follow it
? Have indicator when the remote device is power-off or E1 line is broken or lose signal;
? Have the function of E1 interface loop back check, avoid the converter crashed 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- Negotination, support VLAN
? Ethernet interface supports AUTO-MDIX (crossed line and straightly connected line self-adaptable );
? Have 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 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 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
