Instruction manual

Attendant Console, Switched Loop
The Switched Loop Console derives its name from the ability of the system to hold incoming
attendant-bound calls in a queue and switch them on voice loops to an available console. Calls are
directed to a console in a pre-administered, prioritized sequence. The SLAC differs from the DTAC
in the following basic respects:
● It receives calls one at a time, regardless of the number of incoming calls to the system (at
the DTAC, many incoming calls can be ringing simultaneously).
● It displays pertinent information about incoming and outgoing calls.
● It can serve as an attendant console, a message center, or a combination of both.
● It has speakerphone and Hands-Free Answer on Intercom (HFAI) capabilities.
Fixed Buttons (Figure 2-4)
The SLAC has five fixed line appearance, or “LOOP,” buttons where all incoming calls are
answered. Each button has a red I-use LED and a green status LED. These buttons represent voice
links (loops) between the console and the switch. The loops also provide the paths for outgoing
calls.
In addition to the LOOP buttons and standard multiline terminal buttons (HOLD, TRANSFER, etc.),
the console is equipped with the following feature buttons that provide unique attendant functions.
On the deluxe SLAC, all of these buttons have both I-use and status LEDs; on the basic SLAC, only
the buttons specifically noted have LEDs.
● Start [START]: Initiates the call extending process by placing a caller on hold (on the
Source button) and providing internal dial tone to the attendant.
● Cancel [CANCEL]: Terminates the “Start” operation and reconnects the attendant to the
calling party (on the Source button).
● Release [RELEASE]: Releases the attendant from an active call and completes the call
extending process.
● Source [SOURCE]: Reconnects the attendant to the calling party after a call has been
initiated to the called party but before the two parties have been connected together. (I-use
and status LEDs on basic SLAC.)
● Destination [DEST]: Connects the attendant to the called party again after the attendant
has operated the Source button to speak to the calling party. (I-use and status LEDs on
basic SLAC.)
● Join [JOIN]: Joins together (in a 3-way connection) the attendant and the other parties in
an extended call.
● Forced Release [FORCED RELEASE]: Drops all active parties from a call.
● Last Number Dialed [LAST # DIALED]: Redials the last number dialed.
