Centrex Line Board

Part Number: FXCMW-08 (Centrex Message Waiting Line Board)

• Centrex message waiting loop start-line boards provide message waiting and Caller ID

interfaces.

• With the Centrex Message Waiting feature, a signal from an external message center lights a

message waiting light on the system telephones and causes a message waiting indicator to

display on proprietary LCD speakerphones.

• The service provider sends two different message signals to the FX system: line number with

message waiting status OFF or line number with message waiting status ON. If the message

wait status is OFF, the system removes the message waiting indication from all applicable

stations.

• When the system receives message wait status ON, it verifies that the line is enabled for the

message waiting feature. If this is so, the system responds in either one of two ways:

* The system forwards the message waiting signal to up to four stations that installers have

selected to receive message waiting signals and retrieve the messages, or

* In the absence of the special line programming station assignment, the system verifies

that the stations connected to the incoming message waiting lines have one of the

following conditions assigned:

• Direct message waiting line appearance

• Direct or delayed ringing enabled for the message waiting line

• A message waiting line assigned to the stations as a prime line.

* Once the system verifies that one of conditions is active, it updates the appropriate light

and LCD display to indicate that a message is waiting on the specific line.

• The system queues a maximum of 8 messages at a time for each station including internal

and external messages; however, it ignores any messages beyond this maximum number.
