Backup Telephone Number If the ISP provides a secondary telephone number for Internet
access in case the primary number is unavailable, it can be
entered here.
Number of Retries
If the first attempt to establish an ISDN connection is
unsuccessful, the module automatically redials the number. The
user configures the number of times the number is redialled
within the range 1 - 255. The default setting is 30 retries. The
number of retries applies first to the main telephone number and
then to the backup telephone number if it is enabled. If a
connection cannot be established on the backup number after the
last retry, no further attempt is made to establish a connection.
No limit is placed on the number of retries if ' 0' (zero) is specified
as the number of retries.
Retry Interval
This defines the time interval between retry attempts and is
programmable within the range 5 - 60 seconds. The default
setting is 10 seconds.
Initial Period
During an ISDN call a timer is set to disconnect the call if no data
is sent or received for a period of time.
Three timers are used:
The Initial Period defines the period from the start of the call to
the end of the initial billing period. This can be set by the user to
the initial billing period of the ISDN call. This information is
available from the service provider. The range is between 0 and
60 minutes. The default setting is 3 min.
Recurring Period
The Recurring period defines the recurring billing period. The
range is between 0 and 60 minutes. This can be set by the user to
the recurring billing period of the ISDN call. This information is
available from the service provider. The range is 0 to 60 minutes.
The default setting is 3 min.
Idle Timer
The Idle timer monitors the call for a period before the expiry of
the initial billing period and subsequent recurring periods. If no
data is present during the idle timer period, the call is
automatically disconnected at the end of that billing period. The
default setting is 30 secs and the range is 0 - 120 secs.
If the Initial Period and the Recurring Period are set to zero, no
cost control is applied and the call will always remain connected
