Instruction manual

Attendant Console, Switched Loop
Considerations
One System 25 configuration can support either one or two SLACs or one or two DTACs,
but not a combination of a SLAC and a DTAC.
The optional Direct Extension Selector Console can be connected to a SLAC to provide
busy/idle status of inside stations and quick calling of their extension numbers. In a system
with two consoles, either or both can have a Selector Console as an adjunct. The Selector
Console is covered in the “Attendant Direct Extension Selector Console” feature description.
For information on related Attendant Features (Table 2-E), refer to the individual feature
descriptions.
Interactions
The following features interact with Switched Loop Attendant Console.
Attendant Console, Direct Trunk: The SLAC cannot operate in the same system with a
Direct Trunk Attendant Console.
Bridging of System Access Buttons:
The SLAC cannot serve as a principal or a bridging
station.
Callback Queuing: The attendant can queue calls that are extended using the normal
START-RELEASE button operation. However, calls originated using only the START button
(no other call put on hold) cannot be queued.
Call Originations:
Placing a new call from an active console causes interactions with the
currently active call. At a console that has the default Automatic Release feature, the active
call is dropped when the attendant presses a new LOOP button. The new loop becomes the
active one; dial tone is provided, and the attendant can dial a number. If the optional
Automatic Hold feature is administered, the interrupted call is put on hold instead of being
lost.
If a new call is originated with the START button or at the Selector Console, the active call is
split. The current loop becomes the active loop for the new call. The display shows the split
call information. This is the normal operating procedure for extending calls.
When a REP DIAL button is pressed while the console is active on a call, the active party is
not dropped or split, and the display does not change. If the active call is with an inside
station, the digits generated by the REP DIAL button are ignored. But if the active call is on
an outside trunk, then pressing REP DIAL will cause the digits stored on the button to be
sent out over the trunk (“thru-dialing” or “end-to-end signaling”).
When an active call is put on hold manually by operation of the HOLD button, the system
does not automatically select a new loop for placing a call. In this case, the attendant can
select a new loop by pressing an idle LOOP button, then dial a number. Pressing a DSS, Flex
DSS, Auto Intercom, Last Number Dialed, REP DIAL, or Selector Console button will select a
new loop and dial a number in a single operation.
