Single Line Installation

E. Total Supervision with Multiple SR's


Ring Supervision:


Barge-in Protection:


Install, Ease/Expense




If total ring supervision is required for more than one phone, and barge-in protection is not needed, buying additional SR Call Processors may be less expensive than changing your wiring, especially if your site is wired in a user-unfriendly way, or if your extensions are in other buildings.

For EACH location where you want the phone or data device to ring on only one number:


  1. Unplug any cord attached to the wall jack. Connect the “LINE” jack of your SR to the wall jack with the supplied line cord.

  2. Reconnect your phone or data equipment to the proper DEVICE jack of the SR, depending on which number you want it to respond to.
