Chapter 9, Port Sharing

An IVS message can be requested by either a call guide command (step) or the Whisper

Messaging function.

If an IVC device is immediately available, the system delays for the duration defined by

the Share Wait Time value to allow other calls to request the same message. During this

delay, if a number of calls equal to the Maximum Count for Share value request the same

message, the IVC device immediately plays the message.

If an IVC device is not immediately available, the system waits for one. If a call guide

step makes the request, the system waits for as long as specified in the call guide. (If an

IVC device is not available within that time, the switch proceeds to the next step in the

guide.) If Whisper Messaging makes the request, the system waits for the duration

specified by the Whisper Device Wait Time (WDW) parameter in the associated User

Group (UGRP). If a port is still not available when the WDW time expires, the system

removes the request from the queue. If a port becomes available within the WDW time,

the system continues to delay for the remainder of the Share Wait Time duration, if any,

or until the number of calls waiting for the message reaches the Maximum Count for

Share value.

Delays between phrases can effect the IVS Port Sharing function. See "Special Handling

of IVS Phrases, Data, and Pauses."
