Station Message Detail Recording (SMDR)
The SMDR call detail (Figure 2-48) 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)
The time the trunk is seized is listed using a 24-hour clock. For example, 2:01 PM is listed
as 14:01. Seconds are truncated.
● Blank (Column 17)
● CALLED NUMBER (Columns 18-35)
For outgoing calls, up to 15 digits may be recorded, excluding the ARS or facility access
code but including the 0 or 1 prefix (to identify local and toll calls) and 950-10xx and 10xxx
interconnect access codes. 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 Dialing and Speed Dialing 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.
For a Remote Access call through the System 25 to an outside number, this field contains
the outside number dialed by the remote caller.
An incoming call is identified by the word IN.
● Error Character - Question Mark or Blank (Column 36). Indicates number dialed exceeded
15 digits.
● Blank (Column 37)
● DUR (Columns 38-45 - Duration)
For incoming calls, this provides the time between trunk seizure and disconnect, rounded to
the nearest second. For outgoing calls, it provides the time between the last digit dialed
until the last station on the call hangs up, less an estimated time for call setup (15
seconds), rounded to the nearest second. A call transferred between a number of voice
terminals will reflect the total call duration. The maximum time that can be reported is 95
hours, 59 minutes, and 59 seconds.
