Resync At (HHmm) The time of day when the device tries to resync. The
resync is performed each day. Used in conjunction with
the Resync At Random Delay.
Default setting: blank
Resync At Random
Delay
Used in conjunction with the Resync At (HHmm) setting,
this parameter sets a range of possible values for the
resync delay. The system randomly chooses a value from
this range and waits the specified number of seconds
before attempting to resync. This feature is intended to
prevent the network jam that would occur if all
resynchronizing devices began the resync at the exact
same time of day.
Default setting: 600
Resync Periodic The time interval between periodic resyncs with the
provisioning server. The associated resync timer is active
only after the first successful synchronization with the
server. Setting this parameter to zero disables periodic
resynchronization.
Default setting: 3600 seconds
Resync Error Retry
Delay
Resync retry interval (in seconds) applied in case of
resync failure.
The ATA has an error retry timer that activates if the
previous attempt to sync with the provisioning server fails.
The ATA waits to contact the server again until the timer
counts down to zero.
This parameter is the value that is initially loaded into the
error retry timer. If this parameter is set to zero, the ATA
immediately retries to sync with the provisioning server
following a failed attempt.
Default setting: 3600 seconds
