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.
Refer to
“Defining user preferences” on page 428 for information about
assigning a distinctive ring pattern to a telephone.

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 appear 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.
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 .
