Main function: Realize Ethernet over PDH with protocol ITU-T G.7041, G.7042, G.7043, G.8040 and able to work with converters from third party device.

Interface features:

Transmission interface

• Support auto delete the fault E1 channels(BER more than 1E-6 or a series warning LOS/AIS/LOF or the signal loop back); auto-restore the use of E1 after eliminate the failure.
• For 16E1 channels, the maximum tolerable time delay difference between any two can be up to 220ms. It will have an alarm for exceed the limit when the time delay difference over 220ms, meanwhile, business interrupt jitter tolerance, jitter transfer characteristics in the line with ITU-T G.823.

Ethernet interface

• Provide 4 maximum shared Ethernet interface, support VLAN division based on interface, in the line with IEEE802.1Q standard.
• Provide MAC address table with 1024 pieces, 5 minutes aging time.
• Support frame length: minimum 64 bytes, maximum 1916 bytes
• Provide flux statistics for each Ethernet interface, such as the fault package number and total package number etc.
• Provide PAUSE flux control function, can be equipped with network management.

Management interface

Support RS232 or SNMP network management function. (optional)
