3.1 HOW THE OCTEL OVERTURE 200/300 WORKS WITH THE
PHONE SYSTEM
The Octel Overture
t200/300 message servers work with PBXs, Centrex, most hybrids, and some key
systems. The Octel Overture 200/300 is configured with its voice ports connected to the phone system as
a series of DTMF touchtone single line analog extensions (touchtone sets). In the PBX, these extensions
are programmed to receive an incoming call, to place outgoing calls (within the PBX for message waiting
and also outside the PBX for offsite paging and alarm calls), to place calls on hold, transfer calls, and
reconnect if the called party does not answer. This configuration is referred to as “behind the switch”
because the ports are on the extension side, not the trunk side, as illustrated in Figure 3-1.

how to order them. It assumes familiarity with some PBX concepts.
Changes need to be made to the phone system for Octel Overture 200/300 message servers. Some are
changes to the PBX; others are done in the Public Exchange (PE). This may require lead time. Work with
the client to determine who will make the changes and how long they will take. Prepare a schedule so
that everyone knows who is doing what and the date each item is required.

25-pair cable connects the Octel Overture 200/300 line card to the PBX extension. A PBX extension
connected to a Octel Overture 200/300 port is referred to as a port extension.
In order for the Octel Overture 200/300 to extend calls correctly, each port extension must be configured
in the PBX to receive calls, place them on hold, initiate, transfer, and reconnect calls.
