First, device FE0 port connect PC with string, and then fill FE0 IP address in browser, FE0 default
IP address is 192.168.1.111. It will request customer to input user name and password. Default
user name and password are “admin”.
If customer modified the default IP or forgot the IP, that can’t enter the configuration page.
Please connect PC and device serial with the serial line. Enter the CLI to view or modify the
equipment IP. Here IP is set to 172.16.33.60. In addition, hold down the RST button to restart the
device, customer can regain the port’s default IP. Then enter the IP address of device in the
browser address bar. Customer will see the following page.

E1/T1 Port Status
1. LOS Alarm: Signal loss alarm, this alarm is created when receiving is lost; please check
the physical connection whether disconnected.
2. RAI Alarm: Receive remote alarm indication, it is a signal transmitted in the outgoing
direction when a terminal determines that it has lost the incoming signal. Receiving
remote alarm indication (RAI) means the far-end equipment over the T1 line has a
problem with the signal it is receiving from the upstream equipment.
3. AIS Alarm: The Alarm Indication Signal (AIS) failure is declared when an AIS defect is
detected at the input and the AIS defect still exists after the Loss of frame failure which is
caused by the unframed nature of the 'all-ones' signal is declared. The AIS failure is
cleared when the Loss Of Frame failure is cleared.
4. Disable: Means that this E1/T1 is not used.
5. ISDN/SS7 Signal Alarm: Means physical connection is normal, signaling link has
problem.
6. Active-OK: Means that physical connection and signaling link are normal.
E1/T1Channel Status
1.Frame-Sync: Non voice channel, which used as a synchronization channel
2.Idle: Means this channel is idle, when the channel is enabled and the cable is
connected OK.
3.Signal: Signal channel
4.Busy: Means this channel is occupied by voice
5. Fault: The channel is enabled but the cable is not connected.
6.Disable: Have not use this E1/T1 trunk
