Modes of operation

Introduction

Digital telephones at your Remote Office 9150 site can operate in the following

host-controlled

local-controlled

online to host PBX

offline from host PBX

Host-controlled mode

Host-controlled mode means that the host PBX controls the following:

some display messages that appear on your telephone

indicator updates such as the message waiting indicator

calls that you receive from or make 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

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
