Description
Figure 2-18 Sample SMDR Report in ISDN format
The Station Message Detail Recording (SMDR) feature is used to capture
detailed usage information on incoming and outgoing voice and data calls. The
information is sent to an optional output device such as a printer or an optional
call accounting system.
SMDR records are gathered sequentially on a real-time basis and sent to the
RS-232 SMDR jack on the processor module of the control unit. Or to assist
further with cost allocation and unauthorized call detection, the information can
be directed to a serial printer or PC with an AT&T Call Accounting System
(CAS/B, CAS/H, CAT/B, or CAT/H) application. The printer or PC is also
connected to the SMDR jack on the control unit.
Two SMDR report formats are available: the factory-set basic format or the ISDN
format. The ISDN format is used when the business subscribes to the AT&T
INFO2 automatic number identification service (ANI). When the ISDN format is
selected during system programming, the number identification information is
printed in the "Called Number" field of the call report. The rest of the fields are
identical to the basic format.
Call information can be recorded for the factory setting of incoming and
outgoing calls or for outgoing calls only. In addition, the system is factory-set to
record only calls that last at least 40 seconds. The setting can be changed to
0-255 seconds.
For outgoing calls, the timing begins when the user selects a facility and lifts the
handset. The timing restarts when dialing is completed (the system detects end-
of-dialing). If incoming calls are included on call reports, the timing begins when
a user answers the call. The timing is stopped for both incoming and outgoing
calls when the call is disconnected. If the duration of the calls is more than the
programmed amount of time for SMDR recording, the system generates an
SMDR record.
Figure 2-18 shows a sample SMDR report.
