¥ Check the frame types using the eth list command (page 181) and ensure that they are the same on
both routers.
¥ Check that the Ethernet cable is correctly plugged in.
¥ Make sure that the Novell server is up.
Incorrect VPI/VCI (ATM Routers)
If you are given an incorrect VCI/VPI number or none at all to use for the remote, and you need to determine
what the possible value might be, use the atom findpvc command (see ATM Debug Commands, on page
294).
Problems Accessing the Router via Telnet
¥ Ensure that the router has a valid IP address.
¥ Check that the Ethernet cable is plugged in.
Problems Downloading Software
¥ Ensure that a TFTP server is properly set up to locate the router software.

Trouble-Shooting Telephony Services
After the router WAN link activates (the LINK LED is green), you should get a dial tone. The dial tone should be
received even if you have not yet configured your IP and bridge network settings.
If you do not get a dial tone, check the following:
¥ Does the router have power?
¥ Is the local phone cord plugged in?
¥ Is the voice PVC set correctly in the router? (See the following debug commands.)
¥ Is the WAN link down? (The LINK LED should be solid green.)
¥ Is the DSLAM provisioned for the second PVC?
¥ Is the voice gateway connected and provisioned?
¥ Is the ATM network down between the DSLAM and the voice gateway?
If you hear clicking during heavy data downloads, check that the DSLAM supports quality of service (QOS) and
that the ATM switch has the voice PVC provisioned for vRT and the data at a lower priority.
The Port Monitor GUI program can show you the voice PVC and the last event message. The following debug
commands may also be helpful.
ifs Shows whether the data and voice PVCÕs are configured and percent loading.
For ATM routers:
atom voice Displays the voice PVC.
atom voice <x*y> Changes the voice PVC to the specified x*y.
For Frame Relay routers:
