7.2.4 D Channel Access Control
The D channel access control includes collision detection and priority management. The collision detection is always enabled.
The priority management procedure as specified in ITU-T I.430 is fully implemented in W6692A.
A collision is detected if the transmitted D bit and the received echo bit do not match. When this occurs, D channel
transmission is immediately stopped, and the echo channel is monitored to attempt the next D channel access.
There are two priority classes: class 1 and class 2. Within each class, there are normal and lower priority levels.

The selection of priority class is via the AR8/AR10 command. The following table summarizes the commands/indications
used for setting the priority classes:
