NOTE: You must configure a D-channel and B-channels to complete your ISDN PRI
line configuration.
NOTE: You can configure dso-options on the B-channel, but you cannot configure
parameters for a D-channel. However, when interface statistics are displayed, both
B-channel and D-channel interfaces have statistical values.

You can configure the system to allocate B-channels for dialout from lowest or highest
