4.2.6.6.3.5.7 SU Burst Duration for High Priority Traffic
The SU Burst Duration for Ligh Priority Traffic parameter defines the maximum
duration of a burst that can be made by the SUs served by the AU for high
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 high priority packets.
The default is 8 (2 milliseconds).
4.2.6.6.3.5.8 SU Burst Duration for Low Priority Traffic
The SU Burst Duration for Ligh Priority Traffic parameter defines the maximum
duration of a burst that can be made by the SUs served 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:
4.2.6.6.4.1 DRAP Support
The DRAP Support option enables or disables the DRAP feature that offers the
possibility of identifying the connected Gateways and limiting the maximum
number of voice calls made by Voice Gateways in a cell.
The default option is Enable.
4.2.6.6.4.2 UDP Port
The UDP Port parameter defines the UDP port used by the DRAP protocol.
The range is from 8000 to 8200.
The default value is 8171.
