ASAI-Provided Dial-Ahead Digits

ASAI-Provided Dial-Ahead Digits

The ASAI-provided digits feature allows an adjunct to include digits in a Route Select capability. These digits are treated as dial-ahead digits for the call. Dial- ahead digits are stored in a dial-ahead digit buffer and can be collected (one at a time or in groups) using the “collect digits” vec tor command(s). Although the adjunct may send more than 24 digits in a Route Select, only the first 24 (or 24-x) digits are retained as dial-ahead digits*. An application can use this capability to specify the digits that the switch should pass to the VRU as part of the converse- on vector step.

*The maximum number of dial-ahead digits that can be stored in the buffer is dependent on the number of digits already collected for the call by a previous “collect digits” vector command. If ’x’ digits were collected by vector processing prior to executing an “adjunct routing” vector command, the ’x’ digits collected reduces the maximum number of digits that can be stored as dial-ahead digits as a result of a Route Select. The rest is be discarded.
