Product Description

The control unit ("KSU") is the heart, or brain, of a phone system. It connects to your phones and the incoming lines from the phone company, plus accessories like paging amplifiers, voicemail systems, and music-on-hold sources.

AbleComm sells many different phone system control units. They have different capacities, features and prices, but they all can use both multi-line and single-line phones, and are designed to connect to ordinary analog ("POTS") lines from your phone company. They'll also work on VoIP lines.
