ATTENDANT DIRECT EXTENSION SELECTION
Description
Permits the attendant to extend calls to stations by pressing one or two buttons instead of
pressing START and dialing the PDC or DDC. Each attendant console in a system can have
an associated Direct Extension Selector Console.
A Selector Console can be used with either
a Direct Trunk Attendant Console (DTAC) in an R1V1 or R1V2 system or with a Switched
Loop Attendant Console (SLAC) in an R1V2 system.
The Selector Console is also used by the attendant for simply calling inside stations, in
addition to “extending” calls.
The Selector Console (Figure 2-6) has an array of 100 Direct Extension Selection (DXS)
buttons plus seven Group Select buttons and a Test button. The DXS buttons are labeled 00
through 99. Pressing a Group Select button causes the DXS buttons to be associated with
PDCs from an associated hundreds group. Default assignments for the Group Select buttons
are 200-299, 300-399, etc., up to 800-899. Group Select buttons can be assigned any hundreds
group in the dialing plan.
Pressing a DXS button when off-hook on an incoming call is equivalent to pressing START
and dialing a station.
Such action will busy out the Start facility until the call is released.
The Selector Console can be used to monitor the on-hook/off-hook status of stations in the
system. If the attendant, while on-hook, presses a Group Select button, the Group Select
LED and the LEDs of any busy stations in that group will light steadily.
The DXS button LED (and, in R1V2 systems, the Group Select button LED) associated with
a particular station will flash when one of the following events occurs:
The station calls the attendant
A call extended by the attendant to the station returns on a RTN-BSY or RTN-DA
button (DTAC only) or on a LOOP button (SLAC only)
The station is covered and a call to it is redirected to a COVER button (DTAC only)
or to a LOOP button (SLAC only).
The LEDs stop flashing when the call is answered. When the attendant answers a returning
call, the LEDs will return to the state that reflects the current on-hook/off-hook status of
the station.
In all of the above cases, the Group Select lamp associated with the current
“hundreds page” remains lighted steadily.
An outside call can be parked via the Selector Console by pressing one of the eight DXS
buttons that can be programmed with Call Park extension numbers. On the DTAC, the
facility status LED of the parked call winks (to indicate that the call is on hold) and the
status LED on the Selector Console lights steadily. On the SLAC, the call is removed from
the attendant console, with the Selector Console LED lit steadily.
A call parked via the Selector Console and not picked up within 2 minutes will return to the
console.
The status LED of the parked-on button will flash while the call is ringing the
attendant.
A call parked via the Selector Console can be picked up at any voice terminal by dialing the
Call Park retrieval code (*8) and the number on which the call is parked.
