FEATURES AND SERVICES
Attendant Console, Switched Loop
Description
In System 25, the Attendant Console is used to answer incoming trunk calls that are
specified to ring at an attendant position, to 
answer calls from inside users, to extend calls to
inside stations and outside numbers, to assist system users in placing outgoing calls, and to
set up conferences.The attendant can also manage and monitor some areas of system
operation. System 25 supports the Switched Loop Attendant Console (SLAC) or the...

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:
l 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...

Features and Services
l Position Busy [POS BUSY]: Temporarily removes the attendant position from service. (I-
use and status LEDs on basic SLAC.)
l Attendant Message Waiting [ATTENDANT MESSAGE WAITING]: Used by the attendant
to remotely control; Message LEDs on voice terminals. (Status LED only on basic SLAC.)
l Alarm [ALARM]: The associated green status LED flashes when a system trouble has
been detected; the LED can be changed from flashing to steadily lit by pressing the button.

Display (Figure 2-4)
The SLAC contains an alphanumeric call information display. This module is built into the
top of the console. It contains a 16-character 5x7 dot matrix liquid crystal display, timer
controls, and a thumbwheel Contrast adjustment.Timer functions are available only when
the attendant presses the Local button. The Time/Timer Exit button allows the user to select
ordinary clock/calendar display or a timer.In the Time mode, Set, Fwd, and Rev are used to...

FEATURES AND SERVICES
Placing a Call on a LOOP Button
In general, originating a call at an idle SLAC involves going off-hook and then dialing the
desired number. If the console is not idle, the attendant can generally use one of these
procedures:
l Split the active call (that is, put it on temporary hold by pressing the Start button) and
place another call on the same button; this is the normal call-extending procedure.
l If the Automatic Hold feature is enabled, press another LOOP button to place a new...
