Dial Out/Initial Channels
Write security: 3; Read security: 5
This is the number of B-channels to dial-up on the initial connection. Possible
choices are 1 (def) and 2.
Connection List/Bandwidth
The bandwidth parameters that govern this connection are set here.
Bandwidth/On Demand
The parameters under this menu control the data rates required to change
bandwidth.
Bandwidth/Mode
Write security: 3; Read security: 5
When this option is set to
On, the Express XL/XLT will apply its bandwidth-
on-demand features for this Connection List profile. If set to Off, none are per-
formed.
Bandwidth/Idle Timeout
Write security: 3; Read security: 5
This is the number of seconds the ISDN line must be idle before hanging up
this connection. A value of 0 (def) means the Express XL/XLT will never drop
the link based on the idle timer. The range is 0 to 255.
Bandwidth/Preempt Time
Write security: 3; Read security: 5
Occasionally an application will require to connect to a different location be-
fore the current connection’s idle timer has timed out. This causes the appli-
cation to have to wait for idle timer before it can use the B-channel. This
preempt time allows the Connection List that is active to be dropped sooner
than the normal idle time. 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 preempted.
If set to 255 (def), the connection is never preempted. If set to 0, the connection
is disconnected immediately when another application is requested.
