AT&T MERLIN LEGEND Release 3.1 System Planning Manual page 161

Group-Assigned Features
The system automatically reserves extension numbers 770 through 791 and
7920 through 7929 for calling groups (these may be changed). If operators with
DSSs need one-touch Group Calling, renumber the extensions that fall within
the Page button ranges.
If the system has AUDIX Voice Power/Fax Attendant System, certain extension
numbers are reserved as follows:
Calling groups can be part of the group assignment for Night Service as
described later in this chapter.
Planning Form Instructions
1. Review the Employee Communication Survey analysis and determine the
number of calling groups needed using the following guidelines:
Assign up to 32 calling groups with up to 20 members for each group.
Each telephone user can be a member of only one calling group.
Designate particular lines/trunks to ring directly into a calling group.
Incoming calls on a given line/trunk can be directed to only one
calling group.
If the AT&T Attendant or another VMS is being used, reserve one or
more calling groups for that feature.
2. For each calling group, make a copy of both sides of Form 7d, Group
Calling.
3. For each group, on the front of Form 7d, list the extensions and
lines/trunks assigned to the group:
a. Write the group number in the Group No. space. Start with
number sequentially.
b. Write the name of the group in the Group Name space (see the survey
analysis).
NOTE:
If the system has AUDIX Voice Power/Fax Attendant System, fill in only
the group number and group name here, then fill in the rest of the
Group Calling information on Forms B and C of the AUDIX Voice
Power planning forms.
