System information
Glossary
GL-6 Issue 1 October 1997
callback number
In AMIS analog networking, the telephone number transmitted to the recipient machine to be used
in returning messages that cannot be delivered.
call classification analysis (CCA)
A process that enables application designers to use information available within the system to
classify the disposition of originated and transferred calls.
call coverage
A switch feature that defines a preselected path for calls to follow if the first (or second) coverage
points are not answered. The Lucent I
NTUITY system can be placed at the end of a coverage path
to handle redirected calls through call coverage, send all calls, go to cover, etc.
call data handler process (CDH)
A software process that accumulates generic call statistics and application events.
call detail recording (CDR)
A switch feature that uses software and hardware to record call data. See also call detail record-
ing utility (CDRU).
call detail recording utility (CDRU)
Applications software that collects, stores, optionally filters, and outputs call detail records for
direct or polled output to peripheral devices. See also call detail recording (CDR).
call delivery
See
message delivery
.
call-distribution group
The set of analog port cards on the switch that connects switch users to the Lucent I
NTUITY system
by distributing new calls to idle ports. This group (or split) is called automatic call distribution
(ACD) on System 85, Generic 2, and Generic 3 and uniform call distribution (UCD) on System 75,
Generic 1, and Generic 3. See also automatic call distribution (ACD) and uniform call distribution
(UCD).
call management system (CMS)
An inbound call distribution and management reporting package.
called tone (CED tone)
The distinctive tone generated by a fax endpoint when it answers a call (a constant 2100-Hz
tone).
called subscriber information (CSI)
The identifier for the answering fax endpoint. This identifier is sent in the T.30 protocol and is gen-
erally the telephone number of the fax endpoint.
calling tone (CNG tone)
The distinctive tone generated by a fax endpoint when placing a call (a constant 1100-Hz tone
that is on for 1/2 second, off for 3 seconds).
call vectoring
A System 85 R2V4, Generic 2, and Generic 3 feature that uses a vector (switch program) to allow
a switch administrator to customize the behavior of calls sent to an automatic call distribution
(ACD) group.
card cage
An area within the Lucent I
NTUITY hardware platform that contains and secures all of the standard
and optional circuit cards used in the system.
