Exclusion 2 - 3 - AT&T SYSTEM 25 Manual

This feature applies to multiline voice terminals only.
The Exclusion feature allows multiline voice terminal users to prevent other users with
appearances of the same Personal Line from listening in on or interrupting their calls. It can
also be used in a Principal Station/Bridging Station arrangement by either party to exclude
other inside stations from a private call. Exclusion allows users to exclude the attendant and
other stations from an existing or held call, or to drop other System 25 users from a call.
Exclusion can be applied to only one call at a time. Once Exclusion is invoked on a call it will
remain active until the user either presses the button a second time or disconnects the call.
Pressing the EXCLUSION button at any time during a call, regardless of how the call was
originated, drops all other inside stations and tones. However, pressing the EXCLUSION
button does not drop a queued call. An inside party can be included on a private call by
pressing EXCLUSION first and then adding the inside party.
When Exclusion is invoked on a conference call, all other inside parties will be dropped. If
a private conference including inside parties is desired, the user should activate Exclusion
first and then set up the conference. Any attempt to activate Exclusion while active on an
Automatic Intercom call will
