250 Assigning Trunk/line data
N0008589 3.3
Prime set DN:
None
Assign a telephone to provide backup answering for calls on the line. For an Auto
Answer line, calls are redirected if the received number is invalid or the target line is
busy, and if the
If busy parameter is set To prime .
Each line can be assigned only one prime telephone.
Doorphone note: Ensure that this DN does not belong to a doorphone.
Distinct rings
in use read-only This field shows the Distinct Ring Patterns that have already been assigned to at
least one line.
Distinct ring None
Pattern 2
Pattern 3
Pattern 4 Choose the distinctive ring pattern that you want to assign to the line. This allows
you to provide selective service to calls with differing answer priorities.
When more than one line with the distinct ring settings rings at a telephone, the line
with the highest priority will ring first.
• Pattern 4 has the highest ring priority
• Pattern 3 has second highest ring priority
• Pattern 2 has third highest ring priority
• None has the lowest ring priority.
By default, all telephones and lines are set to None
Warning:
If you assign a distinctive ring pattern to a line, and that distinctive ring pattern has
already been assigned to a telephone, all telephones with that ring pattern will be
reset to pattern 1.
If you assign a distinctive ring pattern to a telephone, and that distinctive ring
pattern has already been assigned to a line, all lines with that ring pattern will be
reset to None.
Auto privacy Y or N Define whether one Business Communications Manager user can select a line in
use at another telephone to join an existing call. Refer to
“Turn Privacy on or off for
a call” on page 270 ( FEATURE 83).

Idle (ROI)
Define whether disconnect supervision, also referred to as loop supervision,
releases an external line when an open switch interval (OSI) is detected during a
call on that line. You must set this to Supervised if a loop trunk has its Answer
mode set to Auto or if you enable Answer with DISA. Disconnect supervision is also
required to conference two external callers. The line must be equipped with
disconnect supervision from the central office for the Supervised option to work.
* These listing only appears for UK analog lines. Note that Earth calling is only
supported by a FEM connected to a Norstar analog trunk module. The GATM does
not support Earth calling, even though the setting appears for the lines on the
module.
^This listing appears only for the Australia profile.
GASM: Trunk must be set to Supervised/Loop guarded if Disconnect Supervision is
enabled on the ATA screen. Refer to
“Determining analog settings” on page 424 .
Tips: The duration of an open switch interval (OSI) before Business
Communications Manager disconnects a call is programmed by the Disconnect
timer setting. Refer to
“Configuring the trunk module to line type” on page 143 .
