IEEE802.3 Ethernet standard compatible

10M/100M and Full/Half duplex through auto-negotiation

Filter the ultra long, ultra short and CRC packet 

Enable transparent transmission of ultra long frame of 2048 bytes.

Provide the full duplex PAUSE flowing control function

 Interface connector RS232,

Provide 1-8 E1 circuit

The E1 number may be not consistent, for instance the local 1^st E1 port can connect the remote 4^th E1 port.

Auto-searching the quantity of available channel in the 8 E1 circuits, and auto-assigning the bandwidth, separate the useless circuit by the network management.

Provide the AIS, LOS, overtime warning and the error rate warning, the warning message and the error data rate can be required by the network management.

Support the error rate limit setting of the CRC in every E1 circuit. The E1 circuit will be shut down if the error rate over the limit. The network management or pins can set the limit.

Provide the function of detaching, framing, transmitting, and serial setting of the Ethernet packet.

Provide the E1 loop function.

Support the error rate checking and the statistics of every E1 circuit.  

Support usability check and self-protection and automatic troubleshooting of 1-84 E1 circuits.

The available bandwidth of the single E1 is 1.984Mbps, the maximum bandwidth of 8 E1 is 15.872Mbps.
