The value ranges from 0 to 255 and is in seconds. When bandwidth
is needed for another application, the idle timer is compared to this
preempt time. If the idle timer is greater, the connection is pre-
empted. If set to 255 (def), the connection is never preempted. If set
to 0, the connection is disconnected immediately when another
application is requested.
Bandwidth/Upper Threshold
Write security: 3; Read security: 5
This is the percentage of bandwidth that must be at least present on
one B-channel before a second B-channel is added. The range is 0 to
100 and is in percentages. The default is 80%, which is equivalent to
51.2 kbps. See the section Bandwidth/Samples (below) for more infor-
mation on how the bandwidth rate is calculated.
Bandwidth/Lower Threshold
Write security: 3; Read security: 5
This is the percentage of maximum bandwidth the bit rate must go
below on two B-channels before one is dropped. The range is 0 to
100 and is in percentages. The default is 30%, which is equivalent to
38.4 kbps. See the section Bandwidth/Samples (below) for more infor-
mation on how the bandwidth rate is calculated.
Bandwidth/Min Channels
Write security: 3; Read security: 5
This represents the minimum number of B-channels that must be up
for this Connection List profile. This value ranges from 0 to 2. The
default is 0.
Bandwidth/Max Channels
Write security: 3; Read security: 5
This represents the maximum number of B-channels this Connec-
tion List profile can have. The allowed values are 1 and 2. The
default is 2. A value of 1 means that no extra bandwidth can be
obtained for this connection.
