Script Execution

selected application, the first command in the exec’ed script is a prompt and collect command with no announcement prompt programmed and with the pound sign (#) programmed as the end-of-string character.

The ‘‘Conversesecond data delay’’ is used to give the VRU time to invoke the selected application before the < data_2> digit string is outpulsed.

The application developer should ensure the administered converse first data delay and converse second data delay timers allow sufficient time for the VRU to successfully collect all outpulsed digits, even during periods of heavy call volume. Loss of digits from <data_2> is an indication the converse second data delay timer needs to be increased.

Script Execution

During script execution, digits input by the calling party in response to prompt and collect commands are collected by the VRU but are not collected by DEFINITY as dial-ahead digits. Also, audible feedback is determined by the VRU.

If an agent from a nonconverse split becomes available to service the call while the VRU script is being executed, the VRU port is dropped from the call, and the caller is immediately connected to the agent. Any digits collected prior to executing the converse-onstep are still available and may be displayed using the CALLR-INFO button.

The entire call is dropped if the caller abandons during the execution of a converse-onstep.

Data Return

This phase is optional and is in effect only if the application calls for the VRU to return information to DEFINITY before returning control to vector processing.

Digits returned by the VRU are treated as dial-ahead digits. The rules for collecting and processing VRU-returned digits are identical to those for collecting and processing Call Prompting digits (see Chapter 5, "Call Prompting").

VRU data return is done in a manner similar to an analog transfer. Specifically, the VRU does an analog switchhook flash, outpulses DTMF digits, and then hangs up. If converse data is returned, the DTMF digits comprise two parts. The first sequence of digits is the converse data return feature access code administered on the DEFINITY Feature-Access-Codes form. The second sequence of digits is the sequence to be passed by the VRU. These digits are collected later during vector processing.
