Selecting Yes (def) causes the Express 4100/4110 to re-dial a call at the 56K 
call type if a 64K call type was unsuccessful.  This will not occur if set to 
No 

or if the original call type was other than 64K.

This is the number of seconds between unsuccessful call attempts made 
during dial-on-demand or during dynamic bandwidth.  The range is 
between 0 and 255, with a default of 15 seconds.

This is the amount of time the Express 4100/4110 waits for a call to be 
answered before giving up the attempt.  Possible values are 15 secs (def), 
30 secs, 1 min, 2 mins  and 4 mins.

 

 Audio directs the call control software to request a  
3.1 kHz  audio circuit as the bearer capability for the 
outgoing calls. The audio option is used with an ISDN 
line configured for voice service.  In some areas, 
audio service costs less than data services. An audio 
call type does guarantee a digital end-to-end digital 
connection. 

56K directs the call control software to request a 64 
kbps data circuit that is rate-adapted to 56 kbps.  
Data 56 kbps is intended for use in circumstances 
where interoperability with Switched 56 service is 
desired.

 (def)

The default call type for ISDN service is Data 64 kbps.  
This directs the call control software to request an 
unrestricted 64 kbps circuit.
