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.

This ISDN connection is made

upon initial power-up and

is maintained during the

times defined in the

time-of-day schedule.

Figure 2 - 1 Auto-Call WAN Topology

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.
