Using Remote Office 9150 stations

Modes of operation

Digital telephones at your Remote Office 9150 site can operate in the following
modes:
n
host-controlled
n
locally controlled
n
online to host PBX
n
offline from host PBX
Host-controlled mode
Host-controlled mode means that the host PBX controls the following:
n
some display messages that appear on your telephone
n
indicator updates such as the message waiting indicator
n
calls that you receive from or place to someone at the host PBX site
In host-controlled mode, a voice path is established to the host PBX and
signaling messages are passed between the host PBX and the Remote Office
9150 unit.
Exception: If Local Switchover is enabled, and the station-to-station call is
completed through the host PBX, signaling messages are passed between the
host PBX and Remote Office 9150 unit normally. However, the voice path is
established by the Remote Office 9150 unit without consuming host connection
bandwidth. The host PBX is aware that the call is active and tracks the status of
the phoneset.
If the call cannot be completed through the host PBX, you hear a reorder dial
tone.
