ATT System 25 Reference Manual

							Station Message Detail Recording (SMDR)
The SMDR call detail (Figure 2-48) contains the following information for each call record:
l TYPE (Column 1)
All voice calls are labeled C, data calls are labeled D. (“TYPE” is not printed as a column
heading)
l Blank (Column 2)
l DATE (Columns 3-10)
The date the call is originated.
l Blank (Column 11)
l 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.
l Blank (Column 17)
l 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.
l Error Character - Question Mark or Blank (Column 36). Indicates number dialed exceeded
15 digits.
l Blank (Column 37)
l 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.

							Features and Services
l Blank (Column 46)
l FAC (Columns 47-51 - Facility)
Indicates the facility used to place the call. For outgoing calls including Speed Dialing
numbers, the pooled facility selected by ARS or the facility access code that was dialed (or
that corresponds to the facility button that was pressed) is identified. For Remote Access
calls through the System 25 to outside numbers, this field contains the number of the
outgoing trunk or trunk pool.
For incoming calls, Personal Line calls, and Remote Access calls to inside numbers, the
trunk number is identified.
If a virtual facility was used to complete the call, the applicable Virtual Facility Code (#190-
#199) is identified in this field.
l Blank (Column 52)
l STN (Column 53-56)
Identifies the voice or data terminal responsible for the call. If an account code is entered,
the voice terminal where the code is entered is reported. If no account code is entered, the
terminal originating an outgoing call is identified, or the last terminal connected to an
incoming call is identified.
For an incoming call to a DGC group that is connected to an announcement but is never
answered, 0 will be recorded in the STN field. If the call is answered by a station after
receiving announcement, the station answering the call will be recorded.
If an outgoing call is originated by a tandem tie trunk, the tandem trunk’s Facility Access
Code (FAC) is recorded in this field. If no FAC exists for this trunk, then the 4-digit trunk
number (9xxx) will appear.
If an outgoing call is originated by a DID trunk, the DID’s 4-digit number is recorded in this
field.
For a Remote Access call to an inside number, the called party’s number is shown; if the
call timed out to the attendant, the attendant’s number is shown. If the remote caller calls
an outside number, the number of the incoming trunk is presented in this field.
l Blank (Columns 57, 58)
l ACCOUNT (Columns 59-73)
Lists the Account Code associated with the call, if one was entered. On conference and
transferred calls, the first account code entered is recorded and subsequent account code
entries are ignored.
For Remote Access calls, the barrier code number (not the code itself) is shown. (The
barrier code number is replaced by error code for failed remote access calls.)

							Station Message Detail Recording (SMDR)
l Blank (Column 74)
l PDC (Columns 75-78)
Identifies the user responsible for outgoing calls. The user is identified by the call
accountability login (##PDC) entered at the originating voice terminal. If no call
accountability is entered, the PDC field is blank.
Figure 2-49 and Figure 2-50 summarize the Call Record and Call Record Header formats.
Considerations
SMDR provides detailed call information on incoming and outgoing calls. This information can be
used to facilitate cost allocation, traffic analysis, and detection of unauthorized calls,
Interactions
The following features interact with Station Message Detail Recording.
Account Code Entry: Allows users to have an account code or project number associated with
each call record.
Bridging of System Access Button: When an outside call is answered or originated at a Bridged
Access (BA) button, the SMDR record for this call will report the bridging station’s PDC number
under the STN column and the principal station’s PDC number under the PDC column. If the Call
Accountability feature is used when originating a call at a BA button, the PDC column will contain
the accountable (entered) PDC number in place of the principal’s PDC.
If two bridged stations attempt to originate a call at the same time, and if the call is completed, the
PDC number of the station that dialed the first digit is placed in the SMDR records under the STN
column.
Direct Group Calling (DGC): For an incoming call to a DGC group that is connected to an
announcement and never answered, the PDC of the Delay Announcement machine will be reported
in the “STN” field of the call record. If the call is answered by a station after receiving the
announcement, that station will be listed in the “STN” field.
Forwarding: When a call is successfully forwarded to an outside number, the call record will
contain the forwarding station and forwarded-to station numbers.
When a Remote Access caller activates Forwarding at a System 25 station, the SMDR call record
shows the incoming trunk number in the FAC field, the PDC of the forwarding station in the STN
field, and the barrier code number in the ACCOUNT field.
Modem Pooling: SMDR records do not reflect modem pool resource usage.

							Features and Services
Remote Access: Remote Access calls are fully covered in the SMDR call records. Failed remote
calls are shown in account field (see Figure 48).
Tandem Trunking: If an outgoing call is originated by a tandem tie trunk, the tandem trunk’s FAC
is recorded in the STN field. If no FAC exists for this trunk, then the 4-digit trunk number (9xxx) will
appear. No other SMDR fields are affected.
Administration Requirements
System:
l Send SMDR records to SMDR Port (yes or no; default = yes).
l Minimum length (seconds) of successfully dialed calls that are reported by SMDR (10-255;
default = 40).
l Type of SMDR peripheral: CAT or non-CAT (yes = CAT, no = non-CAT).
Hardware Requirements
An AT&T Model 572 printer or any standard RS-232 serial 80-column ASCII printer is required for
printing the SMDR output. The printer must be dedicated to SMDR to ensure that all calls are
recorded. An AT&T Call Accounting System may also be used as the SMDR output device (see
below).
The printer can be directly connected to Port 2 of the ZTN130 CPU/MEM (Call Processing
Unit/Memory) circuit pack or switched access (either on- or off-premises) can be provided.
Connection is the same as described for the SAT.
SMDR port parameters areas follows:
l No parity; bit is set to zero (mark or space),
l 1 start bit, 1 stop bit, and 7 data bits.
l Baud rate defaults to 1200 (can be set to 300).
l DTR (data terminal ready) required from printer.
l RTS (ready to send) and CTS (clear to send) not required.
l No flow control.
Detailed connection information is provided in Figures 2-51 through 2-55.
Maximum cabling distances are provided in Section 5, “Technical Specifications.”
