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 - 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.

64K (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.

Dial Out/Redial at 56K

Write security: 3; Read security: 5

Selecting Yes (def) causes the Express XL/XLT 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.

Dial Out/Delay

Write security: 3; Read security: 5

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

Dial Out/Connection Timeout

Write security: 3; Read security: 5

This is the amount of time the Express XL/XLT 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.

Dial Out/Attempts

Write security: 3; Read security: 5

This value is the number of attempts the Express XL/XLT 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.
