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).
