Ⅰ.  Main Feature

Ø        Realize Ethernet data transmission over 1~8E1

Ø        Comply with ITU-T G.7041, G.7042, G.7043, G.8040. Be able to work with third party device followed same standard ITU protocol.

Ø        Support auto delete the fault E1 channels (BER more than 1E^-6 or a serious warning LOS/AIS/LOF or the signal loop back); Auto-restore the use of E1 after eliminate the failure.

Ø        For 8E1 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.  

Ø        E1 automatic test loop back and cut off function. The E1 channel will be cut off once find E1 signal loop back. Auto-restore the use of E1 after release. Avoid the network storm without interrupting operations.

Ø        Support local E1 channel side loop back function, facilitate to test E1 channels

Ø        Ethernet data will not be damaged if enlarge or reduce the transmission bandwidth by means of network management.
