Hardware Components
NOTE:
A ground-start/loop-start (GS/LS) line port should be programmed for loop-
start operation for paging equipment. If the loop-start port is programmed
for paging, it cannot be used for outside calls unless a PagePac Port Saver
is used.
The PagePac 20 with Zonemate 9 or Zonemate 39 is an external paging system
using dual-tone multifrequency (DTMF) signaling that can be connected to a
line/trunk port programmed for paging operation. Bidirectional paging or
"talkback" is available. For paging systems with multiple zones, only one loop-
start or ground-start line/trunk is required.
This system is compatible with the PagePac 20 set to loop-start or ground-start
operation, and a PagePac 6 Port Saver. The Port Saver allows the paging unit
to be connected to the same loop-start line/trunk used for calls. Calls can be
made and received when the paging unit is not active. The Port Saver is not
compatible with ground-start lines/trunks.
Music-on-Hold and the Music Coupler
Background music can be provided for outside callers on hold or for selected
areas of a building over the loudspeaker system.
NOTE:
If equipment is used that rebroadcasts music or other copyrighted
materials, the user may be required to obtain a copyright license from, and
pay license fees to, a third party such as the American Society of
Composers, Artists, and Producers (ASCAP) or Broadcast Music
Incorporated (BMI). Or a Magic On Hold system, which does not require
the user to obtain such a license, can be purchased from an AT&T or
authorized dealer.
Music can be heard by outside callers on hold by connecting a music source or
Magic On Hold unit to a music coupler. The music coupler must connect to a
loop-start port that has been programmed for Music-on-Hold operation and
must be used with an 8-ohm music source. The loop-start port cannot be
assigned to a trunk pool, cannot appear as a programmed line on system
telephones, cannot be connected to a loudspeaker paging system, and cannot
be on a trunk port assigned to the QCC queue or to calling groups.
When a call is transferred, it is automatically connected to Music-on-Hold if the
system provides this feature.
The PagePac 20 also provides a music source for paging and Music-on-Hold
without a music coupler.
Dial
Dictation
Dial dictation through a customer-provided dictation unit can be used as either
a system or station adjunct. Some dictation units connect directly to the control
unit via a T/R jack on the 012 module or 008 OPT module, or to a telephone
using an MFM or a GPA. Other dictation units connect to an UPAM that is
