10-31 : Networking Keep Alive Setup
Description
Use Program 10-31 : Networking Keep Alive Setup to set the interval and retry count of the
Aspire Networking keep alive message. The keep alive is used for ISDN and IP networking.
The keep alive message is automatically responded to by the destination Aspire, if the response is
not received the retry count will start. If a response is not received within the number of retries the
networking link will be taken out of service. When the link is taken out of service:
● Any calls that are in progress will be released.
● Park Hold orbits will be released.
● No further Park Hold information will be sent until the link is active.
The link will automatically become active when the next keep alive response is received.
Input Data
Conditions
The keep alive message must be sent and a response not received for the retry count, for the link to
be taken out of service and the calls in progress and Park Hold orbits to be released.
For example: If an ISDN Aspire Networking link is disconnected at Layer 1 then the keep alive
message can not be sent, therefore the keep alive operation will not occur.
