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.

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.

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

3.FAQ
3.1 How to get the IP address if I have modified the default IP or forgot it ?
Customers have two ways to get the IP address:
1) Press the RST button, then users can regain default IP. Refer to 1.2.1 Front View
2) Connect the CONSOLE with your PC Serial Port. The baud rate is 115200 bps. The user name is
"admin"，password is telnet/web login password. If password is reset, the default password is
“admin”. When customers have accessed it and input the command "show int" to get the IP.
3.2 Equipment physical connection to normal, but the network cannot be connected or
network communication is not normal
1) Make sure the network cable is ok or not , can through view the device WAN port or LAN port
indicator light to determine the work states of physical connection
2) Makeing sure the connected network devices (router, switch or hub) support 10M/100M
adaptive.
Else, connecting the Equipment directly to PC and landing Web , then in the "local
connection" .Selecting the correct Ethernet Work Mode
3) Check whether there is a LAN port conflict with the existing IP address
4) Login using the serial port, in the enable mode to view the correct IP and mask, and ping the
same segment of the PC or device to see if can pass.
3.3 Equipment can’t register
If the Run LED flashes slowly, it means unregistered.
1) Check the network connection is working (see above section), whether the Configuration is
Correct.
2) Check whether the LAN firewall setting is inappropriate (such whether limit the network
Communication); If it is, there are two ways to try to resolve:
2.1) Ask network administrators to open limitation with the equipment’s network
communications (it is a special equipment, not afraid of virus attacks);
2.2) Try to enable the equipment tunnel (Through the WEB for Configuration, Also, please
NOTE, open the tunnel will impact voice quality, Please do not enable the tunnel as far as
possible, reference WEB Configuration Interface, Description section).
4) Check whether the Local Network to the SIP PROXY platform network environment is
relatively poor or not, and if so, please check Local Network or contact the service provider.
5) If go through those steps, the device still be in trouble, please contact the equipment provider.
