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” vector 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.
