Customize the ringing of your CENTREX Meridian Business Sets.
Connect the DSI-375 to your Meridian Business Set (MBS) and you will have complete control over your phone’s ringing patterns. The DSI is programmed through the dial pad of your MBS and provides you with ten distinctive ringing choices. You can also program it to allow incoming lines on your MBS to ring normally, even when you are on the phone. The DSI can be programmed to activate a loud Night Bell or illuminate a Set Busy or Message Waiting lamp.
