Telnet Access Problems
• Ensure that the router has a valid IP address.
• Check that the Ethernet cable is plugged in.
Software Download Problems
• Ensure that a TFTP server is properly set up to locate the router software.
• Verify that the router is loading from the network and not from FLASH
memory.
Voice Routing (VoDSL) Troubleshooting
After the router WAN link activates (the WAN or 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 WAN or LINK LED should be solid green.)
• Is the DSLAM provisioned for the second PVC?
• Is the voice gateway connected and provisioned? (If Coppercom or ATM
Standards-based gateway is down or not communicating with the IAD, you
hear dead air.)
• Is the ATM network down between the DSLAM and the voice gateway?
• Is provisioning for loop start or ground start correct? For ground start, tip and
ring may be reversed in the RJ11 cable.
If you get a call treatment tone (tritone or 3-stage tone, Voice LED is amber), check
the following:
• Voice PVC is not set in the router or is incorrect.
• WAN link is down (WAN or LINK LED should be solid green when link is up).
• DSLAM is not provisioned for the second PVC.
• Voice gateway is not connected or provisioned (Jetstream and Tollbridge
gateways).
• ATM network is down between the DSLAM and voice gateway.
