RCA THG540 user manual Don’t hear a dial tone when I use a telephone

Chapter 2: Additional Information

zVerify that the cable modem service is Euro-DOCSIS or DOCSIS compliant by calling your cable provider (DOCSIS will only work if the used frequencies are between 93-861MHz).

I don’t hear a dial tone when I use a telephone.

zTelephone service is not activated. If the rightmost light on the cable modem stays on while others flash, check with your TSP or cable company.

zIf the cable modem 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.

zIf using the second line on a two-line telephone, use a 2-line to 1-line adapter cable. For more Usage and Troubleshooting Tips use the web site links provided on the CD-ROM:
