Functions and Examples

or vectors chained to it, do not contain another collect digits command, the extra digits are discarded.

If the caller enters fewer digits than the maximum number specified and does not complete the entry with “#,” a Call Prompting timeout oc curs. The timeout terminates the command, and any digits collected prior to the timeout are available for subsequent vector processing.

Acommon application involving the entering of variable-length digit strings allows the user to dial either the number for the attendant or an extension (to reach the desired destination.) Let’s say the maximum number of digits that can be entered is three. In such a case, if the user wishes to reach the attendant, the

user should dial ‘‘0#.’’ However, if the user chooses to iald a 3-digit extension, the user should dial, for example, ‘‘748’’and not ‘‘748#.’’ Since the maximum number of digits that can be dialed in this case is three, dialing ‘‘748#’’would cause ‘‘#’’ to be saved as a dial-digit(explained later in this chapter). On the other hand, if the caller dials ‘‘748#,’’ and if the maximum number of digits that can be entered is 4, ‘‘#’’ is notsaved as a dial-ahead digit since it is the fourth of four digits that can be entered in this case.

Entering Dial-Ahead Digits

When digit collection for the current collect digits command completes, vector processing continues at the next vector step. However, the switch continues to collect any digits that the caller subsequently dials. These “dialed-ahead” digits are saved for processing by subsequent collect digits commands. Dial-Ahead Digits are explained fully on page 5-14.

Functions and Examples

Call Prompting uses some of the functions found in Basic Call Vectoring. This becomes evident when you compare the command set table for Basic Call Vectoring in Chapter 4 with the one for Call Prompting found at the beginning of this chapter.

Call Prompting also provides some additional functions that involve digit processing. These functions include the following:

■Treating digits as a destination

■Using digits to collect branching information (including Vector Routing Tables)

■Using digits to select options

■Displaying digits on the agent’s set

■Passing digits to an adjunct

■Creating Service Observing vectors
