Line Aux Jacks (Dedicated Lines And Power Failures); Optional Accessories; Special Feature Information - AT&T SPIRIT 308 Administration Manual

LINE AUX JACKS
Dedicated Lines
Two jacks on the 308 controller, and another on the 616 expansion unit, are labeled LINE AUX.
The jacks provide standard telephone service separate from SPIRIT system features, and are
useful as dedicated lines for computer modem(s) and in power failure situations. When LINE
AUX jack 1 on the 308 is actually being used (that is, the device is "off hook" and using the
line) incoming line 1 will be unavailable for use by the SPIRIT system. LINE AUX jack 2
on the 308 controller uses line 2, and the single LINE AUX jack on the 616 expansion unit uses
line 4. The devices may be left plugged in the LINE AUX jacks. As long as they are not in use
they will not interfere with regular use of the lines.
Power Failures
The LINE AUX jacks may be used with a standard single-line telephone during a power failure
when the rest of the SPIRIT system cannot be used. Simply plug one end of a telephone line
cord into one of the LINE AUX jacks and the other end into a standard single-line telephone.
In the event of a long power failure, the administration memory may be lost and all
administered features revert to the installed setting.

Optional Accessories

Optional equipment connectors include modular telephone jacks for an external alert buzzer and
a public address system. Follow the manufacturer's installation instructions provided with the
optional equipment. The music-on-hold connector requires an RCA-type phono plug from
the music source.
NOTE: Users of equipment that rebroadcasts copyrighted music or other material may be
required to obtain a license from a third party such as ASCAP or BMI.

Special Feature Information

Busy Lamp Field (24-button sets only)
The indicator lights next to the auto-dial buttons of a 24-button telephone set show what is
happening on each telephone in the system. If the light is OFF the telephone is idle. If the light is
ON, the telephone is busy. If the light is FLASHING rapidly, the telephone is the source of an
incoming intercom call to your telephone, is returning a transferred call to your telephone,
or is manually signaling your telephone. If the light is FLASHING slowly, the telephone is
receiving an intercom call that may be answered by you using the call pickup procedure.
The indicator lights for the programmable buttons (buttons 26 and 27) programmed for a
feature will show ON when that feature is used. For instance, the indicator lights for all
programmable buttons on a system that have been programmed for loudspeaker paging will be
ON when the loudspeaker paging feature is used.
Call Pickup
The User Manual gives instructions for picking up a call ringing at another intercom extension.
You will hear a busy signal if you try to pick up a call on a line for which your intercom
extension does not have full permission.
