Hello, we understand your concerns with the installation of this modem. The modem once installed will be connected in a manner that all the current jacks in the home will remain unchanged. You will connect to them as you do today and it will provide line power with the installed battery backup in the event of a commercial power loss. The modem will provide the same current as the POTS line does today and you should not detect any thing different with the service. This is being done as a necessity as technology changes making the current equipment obsolete.
