No landline connection/modem light

I just replaced my modem (which had phone ports) with a new one, and I can't get the modem to recognize the phone, which worked fine with the old unit. No panel light, no dial tone, no service. Have restarted the modem 4X now, still no dice. Any way to fix this, or do I need to find the magical customer service number and speak with a human? Current router is a Cisco DPC3941T.

Hello, @ThorrsHammer, thank you for reaching out about your new modem and giving our community a chance to help you get connected. I know how vital those landlines are, so I have your back on this. Plus, using your own modem is a great way to save some money on equipment in the long run. Have you already added your modem to the account or confirm if your new device is compatible with your service? If not please use these links as helpful guides to do just that.

I spent an entire day on someone else’s phone with so called “agents” at comcast. I had to go get my replacement modem and hook it up myself (to avoid paying yet MORE MONEY to have comcast come replace their broken equipment )which I have paid for many times over the years!) I talked to probably 7 or 8 different employees who didn’t seem to understand simple things like I cant go online because there is no internet connection  etc and two I honestly could not understand what they were saying (What country were they in??) I could go on, and on,and on.. Finally one young woman, who was fortunately brighter than all the others got the internet working, and she said it takes 24-48 for the phone stuff to “cycle” around and if the phone still isnt working after that, to call back. (Which I will have to do somewhere elsew as I dont have a smart phone. I will go without a phone another day or two and when It does work, I will be calling them back to let them know______________________!
