FRM220A-5, 8, 16E1-ET100S (5E1, 8E1 or 16E1 with SFP LAN)

A.1.1 Web Management

The “E1 Port” tab is mostly informational. For each of the E1 lines we can observe if there is normal signal,

sync, AIS alarm, RAI, Loss of Multi-Frame and whether the port is active or not.

Loop back for any of the E1 circuits can also be enabled here. The loop back can be used in conjunction with

the integral BERT to confirm link integrity.
