Alternative Access for leased line:
For applications which require high availability even if a remote terminal server
fails, a alternative access may be set.
It is based on the following mechanism:
If the INSYS GPRS 5.0 serial is restarted in leased line operation, the pre-defined
AutoDial default destination is dialed after 20 seconds. If the connection setup
fails, the device will attempt to dial the AutoDial alternative destination. If the
connection setup to the AutoDial alternative destination fails as well or if no
AutoDial alternative destination was entered, the dialing attempt will be repeated
after a waiting period has expired. First the default destination will be attempted
to read, and in case of a failure, the alternative destination. After each failed dial-
ing attempt (this includes both destinations), the waiting period is increased (in
steps of 40, 80, 320, 180 and 3600 seconds). The maximum waiting period is 3600
seconds. After the waiting period has expired, the device will again attempt to es-
tablish a connection to one of the two destinations. The command
AT**LLWAITRST
defines the maximum number of failures. If this maximum
number of failed connection attempts is reached, the device will be restarted.
Only the failed connection attempts to the main destination are rated. The desti-
nation, with which a successful connection is established, will be used as new
AutoDial standard destination until the device is restarted.
