Telephone Service: Before You Begin

Contacting Your Local Cable Service Provider

You need to set up a telephone account with your local cable service provider in order to use your cable modem for telephone service. When you contact your cable service provider, verify the following conditions:

•Does the cable service to your home support two-way, DOCSIS-compatible cable modem access? If your cable service provider does not provide two-way service, this modem will not be able to communicate with your cable service provider’s Internet access and telephone services.

•Can you transfer your existing telephone numbers from another telephony service provider to your current cable telephony service provider? In some areas, you may be able to transfer your existing telephone numbers, or your cable telephony service provider will assign a new telephone number for each current or additional active telephone line. Discuss these options with your cable telephony service provider.

You may also need to give your cable service provider the following information:

•The serial number of the modem

•The Media Access Control (MAC) address of the modem

These numbers appear on a bar code label located on the cable modem. The serial number consists of a series of alphanumeric characters preceded by S/N. The MAC address consists of a series of alphanumeric characters preceded by MAC. The following illustration shows a sample bar code label.

MAC Address Serial Number T10710
