AT&T MERLIN LEGEND Release 3.1 System Planning Manual page 81

Identifying Line/Trunk Jacks
Only connect auxiliary equipment to loop-start or ground-start/loop-start jack
types. You cannot use a line/trunk jack for auxiliary equipment on an 800 DID,
100D, 800 NI-BRI, or 400EM module.
To make it easier to add incoming trunks in the future, connect auxiliary
equipment to the last line/trunk jack(s) on the rightmost module with either LS or
GS/LS line/trunk jacks.
Planning Form Instructions
1. Review the floor plan and Equipment List (if available) to confirm the
auxiliary equipment to be connected.
2. At the top of Form 2c, fill in the line/trunk numbers for each type of
auxiliary equipment planned:
For Music On Hold, write the line/trunk number of the line/trunk jack
designated for this equipment, and identify the music source (tape
player, radio, stereo system, or Music On Hold) on the Music On Hold
line.
NOTE:
If the system uses equipment that rebroadcasts music or other
copyrighted materials, the customer 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). The Magic on Hold system,
which does not require such a license, can be purchased from an
AT&T representative.
For Loudspeaker Paging, on the appropriate row, write the line/trunk
numbers (maximum of 3) of the line/trunk jack(s) designated for the
paging equipment.
For Maintenance Alarm, on the appropriate row, write the line/trunk
number of the line/trunk jack designated for the Maintenance Alarm
external alert.
NOTE:
The last item, Loop-Start Reliable Disconnect, refers to a line/trunk
option and is completed later in this chapter.
