GLOSSARY
Announcements
Announcements are prerecorded messages that give the caller information. If the first
announcement given to a caller is played before the call is queued to any split, it is a
Forced First Announcement.
Answer-Back Code
A code dialed to retrieve a parked call.
Answer Supervision
Answer supervision is a signal, sent from the switch to the serving CO, that tells the CO
to begin recording toll charges for a call. However, while a call waits in queue, AT&T
ACD software often delays sending answer supervision so that the ACD owner/operator
or caller can avoid excessive toll charges. Call vectoring commands work in a similar
manner; several steps behave differently depending on whether answer supervision has
been supplied. The call vectoring commands that most notably affect or depend upon
answer supervision are the announcement, busy, disconnect, and wait commands.
Appearance
See Call Appearance.
Applications Processor
A minicomputer used to support several user-controlled applications such as traffic
analysis and electronic documentation.
ARS/AAR Digit Conversion
ARS Digit Conversion replaces the initial digit of a number dialed after the ARS access
code (or of a call crossed over from AAR) with another digit string. The call is then
muted as if the modified digits were dialed after the AAR access code. AAR Digit
Conversion reptaces the initial digits of a number dialed after the AAR access code with
another digit string. The call is then routed as if the modified digits were dialed after the
AAR access code.
ASAI Adjunct
Any adjunct that makes use of the ASAI (Adjunct/Switch Application Interface) protocol,
including adjuncts that perform Inbound Call Management (ICM) functions.
Asynchronous Data Transmission
A scheme for transmitting data where each character is preceded by a start bit and fol-
lowed by a stop bit, permitting data elements to occur at irregular intervals. This type
transmission is advantageous when transmission is not regular (characters typed at a
keyboard).
