Connecting phone line to modem box

I recieved a Comcast modem for my landline phone but there are no instructions on how to set it up. Does it go into the wall jack? I do not have a computer-just the cable tv. Thanks.

Re: Connecting phone line to modem box

Assuming you got the modem directly from Comcast, connect the coax cable connector on the back of the modem with a coax cable to a wall cable outlet, a phone cable from the back of the modem (the Tel 1 jack) to your phone, and then plug it in. After a few minutes most of the lights on the modem should be lit up, steadily, and once the Tel 1 light is steady, check your phone for a dial tone. 

If you don't get service at this point, call Comcast Activations to help you get set up.
