[Programming Example of MSN Table for ISDN BRI Port 1]
A table can be programmed for each ISDN-BRI port. Each BRI port has 10 MSN locations.
Note
Tenant number and VPS trunk group number can also be assigned in the MSN table.
Tenant number is used to determine the time mode (day/lunch/break/night) for the
corresponding MSN. VPS trunk group number is used in Voice Mail DPT (Digital)
Integration ( 1.23.3 Voice Mail DPT (Digital) Integration).
Explanation:
If the MSN "123-4567" is received from BRI port 1:
1. Checks the number in the table.
Matches the number in location 01.
2. Checks the time mode.
In Day mode:
CLI is enabled. Route to CLI destination.
In Lunch mode:
CLI is disabled. Route to MSN destination, extension 100.
Conditions
• To use this feature, the MSN service must be assigned for a trunk port as the distribution
method ( BRI DIL/DDI/MSN Selection [421]).
• MSN Modification
It is possible to modify a received MSN to make it shorter, which may be convenient when
programming the MSN table. Modification method (removed number of digits/added
number) can be programmed on a trunk port basis.
[Modification Example]
• When using point-to-multipoint configuration with a BRI, do not connect another ISDN
terminal device in parallel with the PBX. As only two channels can be used at one time
with the BRI, the other ISDN terminal device may monopolise both channels.
