AT%P8=n Dynamic Bandwidth Allocation (only available on models equipped with analog
device ports). Specifies whether Dynamic Bandwidth Allocation (also known as Call
Bumping) is enabled or disabled. When enabled, the DIVA T/A will automatically
assign one of the two B channels (both used for data) to an incoming or outgoing
analog device call (voice). When the call is completed, the DIVA T/A automatically
reassigns the second B-channel to the data connection.
n=0 Disable.
n=1 Enable (default).
Note: When BACP/BOD is enabled, the 2nd B channel is assigned as a data
connection only if throughput is above 64KPS. Note also that you can use this
parameter only if the DIVA T/A has been configured for MLPPP.
AT%P9=n Second B-channel Connection Retries. Specifies the number of times the DIVA T/A
tries to connect to the second B-channel when BOD is disabled.
Range: 0-255. Note that when the ISDN Switch Type is set to Singapore (AT!C1=6), the
range is 0-10.
Default: 3.
AT%P10=n Enable/Disable PPP Echo-Request. Specifies whether PPP Echo-Request is enabled
or disabled. Certain services, such as IBM Global Services, require that PPP
Echo-Request be disabled.
n=1 Enable (default).
n=0 Disable
AT!X13=n Second B-channel Retry Delay (with BACP disabled). Specifies the number of
seconds the DIVA T/A waits before it re-attempts to connect to the second B-channel.
Range: 0-65535.
Default: 5 seconds. Note that if the ISDN Switch Type is set to Singapore (AT!C1=6)
then the default is 60 seconds.
Note: The description above applies only if BACP is disabled; for a description of
AT!X13=n when BACP is enabled, see page 51.
