The PACT (Prefix Access Code Translator) feature provides preliminary
translation data for features using access codes that are prefixed by a
special code. A standard numbering and dialing plan requires that individual
line and small business customers' (custom) calling use prefixed access code
dialing for feature access. PACT is offered on a per office basis. The PACT
is NOT used for the interpretation of Centrex dialing customers.
When a call is originated by the customer, a call register is used to
store the data about the call. The customer dials a prefix and a 2 digit
access code (table a). The PACT then looks at the digits to determine what
action should take place. Reorder or special service error messages will be
heard if you enter an unassigned code. If the code is accepted, then that
particular action will be performed. The PACT consists of the PACT head table
and the prefixed access code translator. The PACT feature allows the dialing
of a special code for a prefix. These are the '*' and '#'. If you have rotary,
then '11' and '12' are used respectively. To use PACT, the prefix must be
followed by a 2-digit code. This combination is then defined in terms of type
and subtype (table b).

The subtranslator is always built 100 words long. A word is a binary code
which, when sent as a whole, act as a command. One word is equal to a 2-digit
access code. This subtranslator contains the PTW (Primary Translation Word).
The PTW contains the feature type subtype and feature subtype index to
determine the function of the dialed code. The feature subtype allows four
subtype tables to exist for feature type 31 (LASS). Index 0 is for LASS. Index
1 is used for LASS on a pay per usage basis. Index 2 and 3 are currently not
used.

The PACT function is extremely important for LASS functions. PACT is what
lets you tell your switch what you want done. Without the PACT, communication
between you and your CO would not exist. PACT is the base foundation for the
use access codes.
