Station Message Detail Recording
Use these instructions only if connecting Station Message Detail Recording
(SMDR).
SMDR allows you to keep track of telephone usage. Through this feature
detailed call reports are generated that include information about incoming and
outgoing calls, such as date and time, the length of the call, the trunk used, the
user's extension number, the dialed number, and the account code.
The information in call reports is helpful for billing customers and internal
departments for telephone calls. It helps to identify telephone misuse and
develop records of telephone traffic patterns to improve system efficiency.
SMDR works in conjunction with the Call Accounting System (CAS/B, CAS/H,
CAT/B, or CAT/H) or a serial printer (AT&T 572 printer or equivalent) connected
to the SMDR port on the control unit. The SMDR port is the upper RS-232 jack
on the processor module.
Following are your choices of options if you use SMDR:
Call Report Format Choose either the factory-set basic format or the ISDN
format. Select the ISDN format if you subscribe to the AT&T INF02 automatic
number identification (ANI) service. With the ISDN format, the ANI appears in
the Number field of the call report.
Note: The availability of the caller identification information may be limited
by local-sewing (caller's) jurisdiction, availability, or central office equipment.
Call Length. The system is factory set to record only calls that last at least 40
seconds. You can choose a new setting of from O to 255 seconds as the
maximum length before it is recorded.
Calls Reported. Choose whether information is to be recorded for the factory
setting of incoming and outgoing calls or for outgoing calls only.
Note: To have accurate reports, the system date and time must be set to the
current date and time when the system is installed. Be sure you checked "Yes
for each of these options on Form 1.
