In Figure 92 on 

, the rectangles represent 

the settings of service change parameters in LD11 that affect the desired 
function. The diamonds represent the logical DAC operating mode 
decisions.

The system can, at any time, request information from a DAC port. The 
uploaded parameters contain information about the individual card (card 
type, order code, release information), as well as the status of the configured 
operating parameters. Because the dialogue operations of data calls can affect 
the operating parameters, this is useful to monitor and confirm port settings. 
An additional parameter is listed in the uploaded information: port interface 
mode (RS-232-C/RS-422). The interface is set by the use of jumpers on the 
DAC, and cannot be altered by the service change.

To ensure proper operation of the DAC keyboard and Hayes dialing, the 
system requires the following:

•

The Data DN must have only one appearance.

•

For access to remote hosts, the TNs class of service must allow external 
calls. The Data TN must have the following in its class of service:

— Call Pickup Denied (PUD)

— Call Forward No Answer Denied (FND)

— Call Forward Busy Denied (FBD)

— Data (DTA)
