Data Records: The system prints call records for incoming and outgoing (external)
data calls. Calls are considered data calls if they involve a data extension.
The following list describes the SMDR data collected for each call and the number of
characters in each field. All information is right justified in its field, unless otherwise
indicated. The record is provided in a standard 80-column format. The headings for each
record item are noted in bold type. These headings are printed across the top of each page.
Page advance is determined by counting lines based on a fixed page length. Each record is
followed by a carriage return and a line feed.
The system can provide for the storage of up to 100 SMDR records. If more than 100 records
are received while the printer is disconnected, a message
“Calls Lost Due To Call Record
Overflow” is provided when a printer is re-attached.
The SMDR call detail (Figure 2-10) contains the following information for each call record:
. TYPE (Column 1)
All voice calls are labeled C, data calls are labeled D. (“TYPE” is not printed as a
column heading)
. Blank (Column 2)
. DATE (Columns 3-10)
The date the call is originated.
. Blank (Column 11)
. TIME (Columns 12-16)

Space is allotted for three dashes, one
between the fourth and fifth digits from the right, one between the seventh and eight
digits from the right, and the other between the tenth and eleventh digits from the
right. Numbers longer than 15 digits will be truncated. For Repertory Dial and
Speed Dial numbers,
the facility will be extracted from the stored number and
reported under the FAC heading; the number remaining after the facility is extracted
will be reported as the called number.
An incoming call is identified by the word IN.
