Troubleshooting
If the VoIP ADSL Router is not functioning properly, you can refer first to this chapter for simple
troubleshooting before contacting your service provider. This could save you time and effort but if the
symptoms persist, then consult your service provider.
Problems with the WAN Interface
Problem Corrective Action
Initialization of the
PVC connection failed.
Ensure that the cable is connected properly from the ADSL
port to the wall jack. The ADSL LED on the front panel of
the ADSL Firewall Router should be on. Check with your
VPI, VCI, type of encapsulation and type of multiplexing
settings are the same as what you collected from your
telephone company and ISP.
Reboot the VoIP Router ADSL. If you still have problems,
you may need to verify these variables with the telephone
company and/or ISP.
Problems with the LAN Interface
Problem Corrective Action
Check the Ethernet LEDs on the front panel. The LED should
be on for a port that has a station connected. If it is off, check
the cables between your VoIP ADSL Router and the station.
Make sure you have uninstalled any software firewall.
Can’t ping any station
on the LAN.
Verify that the IP address and the subnet mask are consistent
between the VoIP Router ADSL and the workstations.
