by Andrew Todd, Demand Media

Comcast offers many digital media services for both home and business customers. Services offered by Comcast include digital cable, high-speed Internet and digital telephone. Comcast digital telephone is a voice over Internet protocol, or VoIP, service. VoIP relies on a high-speed Internet connection and a telephone adapter to function. Although a Comcast representative performs the initial setup, there may come a time when you wish to move or disconnect the VoIP hardware in your office. To set up the connection again, you must properly connect the router, modem and telephone adapter.

Step 1

Disconnect the router, cable modem and telephone adapter's power sources.

Step 2

Connect the coaxial cable to both the wall outlet and the coaxial input on the rear of the cable modem. Thread the connector onto each connection to secure.

Step 3

Connect the cable modem to the router using an Ethernet cable. Plug the Ethernet cable into the Ethernet output jack on the rear of the modem and into the "WAN" or "Internet" jack on the rear of the router.

Step 4

Connect the VoIP adapter to the rear of the router using one of the numbered Internet output jacks.

Step 5

Plug a telephone cable into the telephone output on the rear of the VoIP adapter. Plug the other end of the telephone cable into your telephone.

Step 6

Plug in the cable modem's power cord into the wall outlet, then wait approximately one minute for the modem to boot.

Step 7

Plug the router's power cord into the wall outlet, then wait approximately one minute for the router to boot.

Step 8

Plug the VoIP adapter into the wall outlet, and allow the adapter to boot.
