Appendix - Troubleshooting
If you subscribe to video service over cable, the cable signal may not
be reaching the modem. Conrm that good quality cable television
pictures are available to the coaxial connector you are using by
connecting a television to it. If your cable outlet is “dead”, call your
Cable Company.
Verify that the Cable Modem service is DOCSIS compliant and
PacketCable compliant by calling your cable provider.
I don’t hear a dial tone when I use a telephone.
Telephone service is not activated. If the TEL light on the Advanced
Cable Gateway stays on while others ash, check with your TSP or
cable company.
If the TEL light is blinking when the phone is not in use, contact your
service provider.
If the Advanced Cable Gateway is connected to existing house
telephone wiring, make sure that another telephone service is not
connected. The other service can normally be disconnected at the
Network Interface Device located on the outside of the house.
