The measurement unit is 250 microseconds and the range is from 1 to 40 (0.25
to 10 milliseconds) or 0 to disable bursts for high priority packets.
The default is 16 (4 milliseconds).
4.2.6.6.3.5.6 AU Burst Duration for Low Priority Traffic
The AU Burst Duration for Low Priority Traffic parameter defines the maximum
duration of a burst that can be made by the AU for low priority packets.
The measurement unit is 250 microseconds and the range is from 1 to 40 (0.25
to 10 milliseconds) or 0 to disable bursts for low priority packets.
The default is 20 (5 milliseconds).

4.2.6.6.4 DRAP Parameters (AU only)
DRAP (Dynamic Resources Allocation Protocol is a protocol that can be used by
the AU to communicate with Voice and Networking Gateways connected to SUs
served by it, enabling identification of these Gateways. It also enables managing
voice calls made by Voice Gateways (VG).
The AU keeps track of all current voice calls and, upon receiving from a VG a
request for a new call, compares the current number of calls to the maximum
allowed number. If the maximum allowed number has been reached, the AU will
not confirm the request.
The DRAP feature is applicable only for gateways that support DRAP.
The following is a description of DRAP-related parameters:
