Ringing
The SLAC receives normal ringing on incoming calls. Abbreviated alerting (one short burst
of ringing), accompanied by a change in the LOOP button wink rate, indicates to the
attendant that a held call has exceeded the preset hold time interval. Calls on hold can be
administered to continue on hold after the second timeout or to return to console queue.
Abbreviated alerting can also be administered as a reminder for new calls...

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...

FEATURES AND SERVICES
Call Waiting: Calls cannot wait at the SLAC
Callback Queuing: Calls that are originated without use of the START button can be queued
for busy facilities.They are treated like calls from standard multiline stations. A queued call
remains on the LOOP button where it was originated and does not return via the common
queue.
Headset Adapter: Connection of a headset adapter to the SLAC allows the optional use of a
headset instead of the handset in handling calls.
