7.3.1 OPERATION OF AT&T SYSTEM 85 ADAPTIVE INTEGRATION
This chapter explains the PBX and Octelt 200/300 configuration requirements for correct operation of
AT&T System 85 Adaptive Integration that includes message waiting indication and called party
identification.
System 85 Adaptive Integration uses an intelligent connection between the Octel 200/300 and the System
85 PBX. This intelligent connection is provided by the Octel 200/300 ATTIC (AT&T Interface Card).
Each connection to the ATTIC appears to the System 85 as an AT&T digital display phone, called a link.
The interface between the System 85 and Octel 200/300 enables
Message waiting indication (MWI) — Control of message waiting lamps on PBX stations.
-
Called party identification — Identification of the source and original destination of calls forwarded
-
to the Octel 200/300. The Octel 200/300 can process the call and provide call coverage based upon
the type of call and desired coverage.
Any information that the System 85 provides to an AT&T display phone station (either on the display
itself or by the LEDs) is available to the Octel 200/300. This information includes the following:
The trunk access code of external calls that have been directed to the Octel 200/300 for primary
-
answering.
The trunk access code and the original called extension of external calls that have been forwarded to
-
the Octel 200/300
The calling and called extension numbers of internal calls that have been forwarded to the Octel
-
200/300
The extension number of an internal station calling the Octel 200/300 directly.
-
For many applications, Personal Assistance and Auto-Transfer to Assistance are recommended. For
details regarding these two features, refer to Feature Description volume, Customizing Mailbox Features
chapter, for more information.
.
Personal Assistance operates in conjunction with called party identification in integrated systems.
Caution!
Message Waiting Indication. Message waiting indication enables Octel 200/300 to activate and
deactivate the message waiting indicator available on phones that indicate when there are messages
waiting on the Octel 200/300. Message waiting indication utilizes the System 85 Leave Word Calling
(LWC) feature to perform this function.
.
If employees use the Leave Word Calling feature when calling another employee, they will also
light the lamp on that employee's phone. The employee will not know whether the lamp is for the
Octel 200/300 message waiting indication or Leave Word Calling indication, and will have to
check for both types.
