ISDN Configuration Commands
This section describes the ISDN Configuration Commands.
Some of the commands in this section allow you to configure primary
and alternative settings. If the DIVA T/A is unable to connect using
the primary ISDN settings, it automatically tries again using the
alternate ISDN settings.
For example, you could set-up one profile containing information for
calling from both home and the office. If you call mainly from home,
enter information specific to home in the primary ISDN settings and
enter information specific to the office in the alternate ISDN settings.
Command Description
AT!C1=n
AT!C11=n
ISDN Switch Type: Specifies the ISDN Switch
Type for your primary (AT!C1) or alternate
(AT!C11) configuration.
Note: These parameters are static. They do not
take effect until you restart your DIVA T/A.
For North American Firmware
n=0
National ISDN
n=1
AT&T 5ESS Custom
n=9 (default for North America)
Auto-detect switch type. If you have multiple
ISDN line definitions, the DIVA T/A
automatically determines the correct switch type
to be used (National ISDN or AT&T 5ESS
Custom). This auto-detect feature saves you from
having to worry about which ISDN configuration
to use when you are in a different location.
n=255
No alternate switch type. Use this command
when you want to disable all alternate settings.
Entering a valid switch type causes the DIVA T/A
to use the alternate settings if ISDN initialization
has failed using the primary settings.
