Assign DLCs to only the first and fifth station jacks on a digital or analog module.
This includes DLC positions used for calling group supervisors and for the
optional Call Management System (CMS).
The CMS equipment is connected to analog station jacks that are assigned as
DLC positions. You must assign two DLC positions for each CMS (a maximum of
two) connected to the system.
These instructions apply only to systems with analog muitiline telephones.
Two of the optional features for analog multiline telephones require an additional
station jack:
■ Voice Announce to Busy. A user whose telephone has this feature can hear
an announcement through the speaker even though he or she is on a call.
(MLX telephones can also use this feature but do not need an additional
station jack. Single-line telephones cannot use this feature since they do not
have speakers.)
