562 Conference
Once the last set involved in a conference call disconnects, a search is
made of all trunks remaining in the conference call to determine which trunk
has been established in the call for the longest period of time. This trunk
becomes the chargeable TN. Once this trunk disconnects, the process is
repeated so a new chargeable TN can be located.
Attendant Barge-In
Attendant Busy Verify
Conference Control cannot be activated if an attendant has used Barge-In
or Busy Verify during a conference that involves a trunk.
Attendant Break-In
If the attendant cannot break in to a conference call because the call is
supporting the maximum number of callers, busy tone continues and the
Break-In key lamp flashes.
Attendant Console
Three-party Conference (C6D) allows analog (500/2500 type) telephones on
established calls to flash the switchhook and Dial 0 to talk to the attendant.
Six-party conference users follow the same sequence, but the conference
loop is seized and the call is treated as a conference call. When only two
parties remain from the conference, the call is returned to a simple call if
neither of the remaining parties is an attendant console.
Attendant Overflow Position
An Attendant Overflow Position (AOP) call answered on an AOP DN may
be conferenced with another DN.
Autodial Tandem Transfer
The Autodial Tandem Transfer feature is blocked during Conference and
No Hold Conference calls.
Automatic Redial
When an Automatic Redial (ARDL) call is not accepted by the calling party,
the Conference (A03 or A06) key is ignored.
B34 Codec Static Loss Plan Downloading
B34 Dynamic Loss Switching
When a conference connection is established, no pads are switched in on
the trunk side; any extra loss that is required is provided by the conference
circuit based on an algorithm which takes into account the number of lines
and trunks.
