AT!On Outgoing Call Type. Specifies the default call type for outgoing calls when a user
enters an ATD command without a special modifier. Use of a modifier overrides this
parameter.
n=0 Data call using protocol set in AT%A2=n (default).
n=3 Data over voice bearer capability call (North America only)
n=4 Transparent over voice (Audio) (reserved for RVSCOM).
n=5 Transparent over voice (speech) (reserved for RVSCOM).
The n=4 and n=5 options (transparent over voice) send and receive voice data
unmodified to and from the ISDN B channel and the DIVA T/A. When no data is being
transferred, the protocol fills the outgoing ISDN line with ‘voice silence’ bit patterns.
For more details, refer to the RVSCOM documentation.
AT!X56=n Delay between 64K data call failure and 56K data call attempt. If a 64K data call
fails due to network congestion or if a service or option was not available or not
implemented, a 56K data connection is automatically attempted. This command
specifies the delay, in seconds, before the 56K attempt is made.
Values: 0-10 (wait n seconds before retry); 254 (use pre-configured values depending
on region); 255 (do not attempt 56k data call retry).
Default: Australia & Japan, no retry (n=255); all other regions, immediate retry (n=254).
