VMI ports are outward restricted. The factory-set Facility Restriction Level is 0. A
default disallowed list is assigned to the VMI ports which includes the following
entries: 0, 10, 11, 1809, 1700, 1900, 976, 1

In Release 4.1 and later systems, changes to Group Calling coverage delays
affect the Integrated Administration feature of Integrated Solution III (IS III). For

‘‘Integrated Administration’’ on page 328
In Release 5.0 and later systems, the three threshold levels, when set, are
signaled only at programmed Calls-in-Queue alarm buttons. An external alert
lights or sounds only when the number of calls in the queue is greater than or
equal to Threshold 3.

Direct-Line Consoles
A DLC can be a member of a calling group and is normally used as the calling
group supervisor position. Supervisor positions must be assigned to a DLC.
Any of the following telephones assigned as a DLC can be used as a calling group
supervisor’s console:
■
MLX-20L telephones with or without a DSS
■
MLX-28D telephones with or without a DSS
■
BIS-22D
■
BIS-34D
■
MERLIN II System Display Console with built-in DSS
The supervisor must activate Extension Status to see the status of calling group
members and to change their availability; this cannot be done from normal
call-handling operation.
