10 Check the Desk Control Units are Working
The desk control unit has a handset c/w display and allows calls to be handled
separately to the wall control units. If a desk control unit is healthy, the green
Power indicator is lit, no fault indicator is lit and the display shows the current
system status, see typical displays below.
Note
: The desk control unit displays are different for a networked system and a non-networked system.
Display conventions
The symbol ‘>’ by the side of a display entry means that entry is selected.
The symbol ‘*’ in front of an extension name means this extension is calling or you are connected to that
extension.
11 Handling Calls at the Desk Control Unit
Sections 11.1 to 11.4 applies to both a non-networked desk control unit and current master desk control unit on a
networked system. It is assumed that auto-answer mode is enabled; this is the mode most likely to be setup for the
system.
Additional call handling facilities are available for a networked system, see section 16.
11.1 To answer a call
When an extension calls in, the ringer sounds and the display shows the name of the calling extension, see
example below.
To answer the call simply pick up the handset.
The call is automatically connected and you may speak.
11.2 To end a call
Hang up the handset or press
