3-51

Write security: 3; Read security: 5

This value is the number of attempts the Express 4110/4120 will make 
before giving up on the connection. This is effective for manual dialing or 
dynamic bandwidth calls only. The range is from 1 (def) to 255.

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.

The bandwidth parameters that govern this connection are set here.

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 4110/4120 will apply its 
bandwidth-on-demand features for this Connection List profile.  If 
set to Off, none are performed.

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 
4110/4120 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 before the current connection’s idle timer has timed out.  
This causes the application 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.
