An incoming call from the queue to a console appears on one of the five LOOP buttons; the attendant is alerted to the call by audible ringing, a steadily lighted red lamp, and a flashing green lamp. While the call is ringing and while the attendant is handling the call, the system will direct no more calls to the console. After the attendant ends or releases the call or puts it on hold, another call can come in on an idle button.

It should be emphasized that even when all LOOP buttons on a console are idle, only one call can be directed from the queue to the console. If the attendant puts a call on hold, that LOOP button is no longer available, but a new call can come in on another button that is idle.

Answering a Call on a LOOP Button

At an available SLAC, an incoming call will ring at an idle LOOP button automatically selected by the system. The attendant has only to lift the handset to answer the call; pressing the button is not necessary.

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. However, if Prime Line Preference has been changed to a non-LOOP button, the attendant will have to press an idle LOOP button before dialing.

If the console is not idle, the attendant can generally use one of these procedures:

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.

 

 

 

 

 

 

 

If the Automatic Hold feature is enabled, press another LOOP button to place a new

call; the first call goes on hold.

If the console does not have Automatic Hold (that is, it has the default Automatic Release), use the Hold button to put the active call on hold; then select a new loop to place a new call.

Dual Console Operation

A System 25 can be equipped with up to two SLACs, which operate simultaneously when both are in service. Both consoles can receive the same types of calls, or each can be administered to receive only certain types. When one console is out of service (see Position Busy below), most calls are directed to the other. Either or both consoles can function as a message center.

Inside users can reach either attendant by dialing O, or a particular one by dialing the attendant’s PDC. The DID callers use the Attendant DID number.

Position Busy

Operation of the Position Busy button by the attendant makes the console unavailable to most incoming calls from the common queue and directs the calls to another answering station. The only types of calls that are not diverted by Position Busy are Attendant DID, DGC, and PDC calls. The placing of outgoing calls is not affected. When the Position Busy condition is active, the green status lamp of the button lights steadily. Position Busy is similar to the Send All Calls feature, that is not administered on the SLAC.

The Position Busy feature is automatically assigned to a button position (see Figure 2-4)when the console is administered. In a one-console configuration, however, the feature is enabled only if a multiline voice terminal in the system is administered as a receiver of calls
