Make Set Busy Flexible Feature Codes
You can activate Make Set Busy from an analog (500/2500 type) telephone
by dialing the Make Set Busy Activate (MSBA) FFC (defined in LD 57). To
deactivate Make Set Busy, the user dials the Make Set Busy Deactivate
(MSBD) FFC (defined in LD 57) or the general Deactivate (DEAF) FFC (also
defined in LD 57).
Operating parameters
Make Set Busy does not affect incoming Private Line calls.
Feature interactions
Attendant Blocking of Directory Number
The Attendant Blocking of DN feature will override the Make Set Busy
feature. If the dialed DN of the set that has the Make Set Busy feature is idle,
the DN will be blocked and if the DN is busy, busy tone will be heard.
Attendant Break-In
For a telephone with Make Set Busy in effect, Break-In is temporarily denied
to the attendant. The Break-In lamp uses a slow flash to indicate this situation.
Using the Break-In key prior to dialing the destination DN circumvents this
situation. After the Break-In, the telephone returns to its prior status.
If the controlling party goes on hook in a Break-In conference, and is being
re-rung by the attendant, the ringing takes precedence over Make Set Busy
that may be applied to the set.
Attendant Overflow Position
If a telephone that is the only idle AOP DN has MSB activated, calls will not
overflow.
If the AOP DN is a multiple appearance DN, the MSB key should be added
to all telephones with an AOP DN.
If MSB is activated in a Multiple Call Ringing arrangement, the telephone
appears busy. All other appearances of the AOP DN will still receive calls.
This allows the user to leave the telephone and prevent callers from
overflowing and receiving ringback with no answer.
