New phone modem update

I've recieved flyers to update my phone service. I have the old NIU modem outside the house. I plan to get the Cisco modem. I already have a cable modem for the internet ( sb6141).As I understand it , all I have to do is connect the new Cisco modem line 1 port to my existing wall jack and my other phones will be operational. Do I have to activate the new modem? Do I need to disconnect anything outside on the NIU?

  • Hi, you will need to call in and have the modem added to the account or have the store personnel add the equipment to your account while you are there.

    Thanks. Do I have to disconnect the phone wires or cable connection to the NIU outside so it doesn;t interfere with the new modem?
  • If your NIU outside has a short modular plug, unplug it to isolate your house wiring from the outside world and you should be good to go.
