SUBSYSTEM
Definition
ASB150 02 used as subsystem means that the trunks
in ASB150 02 are connected to analogue extension
positions in a superior system PBX, key system, etc.
Use
The function is used when an existing larger system is
to be complemented with one or more ASB 150 02
systems.
The function can also be used when the public
exchange allows the ordering of facilities such as
inquiry and transfer.
The function means that extensions in ASB 150 02 can
initiate inquiry and transfer in the superior system.
Operation
Inquiry
Inquiry in the superior system is initiated by depression
of the key programmed for the function.
A connected trunk in ASB 150 02 will then initiate a
break that the superior system interprets as the recall
signal.
The extension receives dial tone from the superior
system and can then dial the required extension
number.
Transfer
Transfer in the superior system is undertaken by
replacing the handset.
NOTE: Renewed depression of the key will result
in a new recall signal whose function is
dependent on the superior system.
For continued operation, see the "Instruc-
tions for Use" applicable for the superior
system.
Capacity
The number of trunks to the superior system is limited
by the total number of trunks.
This number should not to exceed 60.
Limitations
As the scope of the facility is dependent on the ability
of the superior system to interpret the register recall
signals, it is first necessary to analyse how the
extension positions in the superior system interprete
signals.
NOTE: An inquiry to a superior system means
that there will be no TCD-analysis in
conjunction with number dialling.
An extension who has been assigned a
key for inquiries to the superior system
must be regarded as fully open for exter-
nal traffic. Other TCD-analysis must be
undertaken in the superior system.
Programming
0301
Program key
One of the programmable keys must be assigned the
function recall signal.
Every extension that is to be able to undertake
inquiries to the superior system must be assigned
such a key.
