In Figure 95 on page 501 and Figure 96 on page 502 , 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.
Upload parameters
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.
System database requirements
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)
