how many resources (code channels) to give a CPE. The
greater the weight, the greater influence the current
queue size has on the average queue size. The lower the
weight, the more the average queue size is an actual
average of the current queue size over time.
Max Queue Size (KB)
512
Maximum queue size for each priority queue (high, low,
voice). Once full (Max Threshold) all packets are
dropped.
Min to Max Drop
Probability (%)
10
The probability of a packet being dropped when the Min
Threshold has been reached. The higher this number, the
more likely a packet will be dropped between the Min
and Max Threshold. All packets are dropped at Max
Threshold.
Realtime Min Drop
Threshold (%)
100
The minimum queue size at which voice priority packets
are considered for being dropped. For example, if set to
10% once the queue size reaches 11% or more, voice
priority packets may be dropped. The Max Threshold
Probability field determines if a packet is dropped once
the Min Threshold is exceeded.
High Priority Min Drop
Threshold (%)
100
The minimum queue size which high priority packets are
considered for being dropped. For example, if set to
10%, once the queue size reaches 11% or more, high
priority packets may be dropped. The Max Threshold
Probability field determines if a packet is dropped once
the Min Threshold is exceeded.
Low Priority Min Drop
Threshold (%)
100
The minimum queue size which low priority packets
are considered for being dropped. For example, if set
to 10%, once the queue size reaches 11% or more,
low priority packets may be dropped. The Max
Threshold Probability field determines if a packet is
dropped once the Min Threshold is exceeded.

Priority
Low
, High, Voice Low, High, or Voice. This is the priority given to data
packets associated with this Code Point/Service. The BTS
processes data packets with Voice, then High priority before
Low priority packets.
