Using Remote Office 9150 stations

Indicator updates

Digital telephone indicators reflect the current status of the telephone. For
example, they identify when calls are waiting, active, or on hold, or, if your
office has voice mail, that messages have been received.
Indicators are updated as follows:
n
by the host PBX when a connection between the host PBX and Remote
Office 9150 unit is active
n
by the Remote Office 9150 unit for feature keys defined on stations with
local call capability
Host-controlled indicator updates
Indicators for host-controlled features are updated automatically by the host
PBX each time
n
an incoming call is received by your site from the host PBX
n
an outgoing call is made from your site through the host PBX
n
a message waiting indicator (MWI) update is received by someone at your
site
Note: If the PSTN is being used and the Remote Office 9150 unit is configured
with a permanent (always on) connection to the host PBX, the ISDN BRI
service is active and telephone indicators are always updated.
If the IP network is being used to route calls, indicators are always updated.
Locally controlled indicator updates
The following indicators are updated by the Remote Office 9150 unit (that is,
these indicator updates are locally controlled):
n
host and local call appearance key indicators
The indicator lights when the handset is taken off-hook, or when you press
the call appearance key to go off-hook.
