Features

There are many applications for your SR Call Processor in the home or small business. To optimize the phone configuration that is best for you, it is important to understand the features available from your SR Call Processor.

• Exclusion Feature
  Both SR models have an exclusion feature which allows you to control line accessibility between your phone devices. This feature can be activated by the protection switch labeled “Barge-In” on the front panels of the SR2 and SR3. (See inside front cover for end-panel view).
   

  1. “Barge-In” Protection On
     This setting enables you to protect phone conversations and data transmissions from being interrupted by other phone devices on the same line. When extensions are picked up a busy signal will be heard.

  2. “Barge-In” Protection Off
     This setting allows you to answer any incoming call from any extension in the home or business. In addition, you can conference any call from any extension.
      

• Surge Protection
  This feature is standard for both the SR2 and SR3.

  Harmful voltage spikes will be carried to the earth ground through the SR’s internal surge suppression network when the SR is properly installed.
   

• 2/3 Port Select Switch [SR3 only]
  This switch allows you to configure your SR3 to operate with either 2 or 3 numbers. In the “2” position, calls will ring through to Device 2 in the shortest possible time. If you have 3 numbers, the switch must be set in the “3” postion.
