Isdn Connection Management

Auto-Call (Time-of-Day Connections)

An Auto-Call connection is an ISDN connection that is established each time the P840 attempts to start the link. This starting of the links occurs each time a P840 powers up or when the link goes through a restart or at the times specified by the Time-of-Day Activation Schedule. An Auto-Call connection would be used for a static WAN configuration that needs to be maintained at all specified times between sites.

The semi-permanent connection that results from an Auto-Call configuration means that the P840 will attempt to maintain a connection to the partner P840 during the times specified in the Time-of-Day Schedule. When Connection Management is enabled, the ISDN call to the Auto-Call number may be suspended during periods of inactivity.
