							Call Detail Recording (CDR)
Issue  3   March 1996

nCalls returned to a vector directory number (VDN) via the VDN Return 
Destination feature associated with Call Vectoring and Call Coverage 
features.
nInternal, direct calls that are originated by an extension optioned for 
intraswitch CDR, or that have a dialed number which is optioned for 
intraswitch CDR (the Intra-switch o ption on the ‘‘Change System 
Parameters CDR’’ form must also be turned on).
NOTE:
If an extension optioned for intraswitch CDR is neither the originator 
of the call nor the d ialed numb er of the call, no CDR record is output 
even though the extension might be a party on the call (via Call 
Pickup, Call Forwarding, etc.).
You have the option of turning off CDR generation for incoming calls, specific 
trunk group(s), intra-switch calls, Non-Call Associated Temporary Signaling 
Connection (NCA-TSCs), Call Associated Temporary Signaling Connection 
(CA-TSCs), and ineffective call attemp ts with the change sys cdr command.
Intra-Switch CDR
Intra-Switch CDR is an a dministrable op tion that allows CDR records to be 
generated for some internal calls. An Intra-Switch call is one that originates and 
terminates on the same switch. The maximum number of extensions you can 
administer for Intra-Switch CDR varies from switch to switch.
If your system can record more than 100 stations, the system only displays two 
p a ges of extensions (112 per page) at one time. When you enter the  add 
intra-switch-cdr command to a dd extensions, the system automatically begins 
after the last extensions. For example, if you add 575 extensions, the first field on 
the first of the two p ages is field 576. If you enter the change intra-switch-cdr 
command, the system d isplay b egins with the first extension administered. If you 
enter the change command with an extension number, the system b egins the 
display with that extension.
Splitting of CDR Records
Where long-distance calls are expensive and difficult to set up, the call transfer 
feature is commonly used among different parties (that is, call splitting) to 
optimize the use of the connections. It is, therefore, important to provide accurate 
cost allocation data for each leg of the call.
For outgoing calls only, an administrable option is provided in G3i-Global, G3V2, 
and later releases that creates a separate call record  for each leg of calls that are 
transferred, attendant handled, or conferenced.

CDR Privacy
To ensure the privacy of calls, an administrable option is provid e d that allows up 
to seven digits of the ‘‘Dialed Number’’ to b e blanked from right to left from the 
CDR record . This blanks the least significant digits. Certain countries have 
requirements that specify a certain number of digits must be blanked from every 
call.
NOTE:
When an adjunct originated call is made on behalf of a hunt group and the 
CDR system parameter record hunt group or member extension option is 
set to group, then CDR p rivacy d oes not a p ply. If this field is set to member, 
privacy does apply.
NOTE:
Certain report processors do not support this option.
VDN Return Destination
VDN Return Destination is an administrable option that allows users to re-route 
calls to an administrable VDN when all parties on the call drop, except for the 
originator. When the call re-routes to a return destination VDN, it goes back into 
the vector p rocessing specified b y the return destination VDN. The originator c an 
then be re-routed to other destinations without having to hang up and redial or 
enter an identification number. Refer to  the Interactions section for details of how 
CDR interacts with VDN Return Destination.
Resource Limitation Call Record Handling
Options
G3rV1, G3V2, and later releases p rovide G2-like capabilities for handling of calls 
when CDR resource limits are exceeded. If new calls come in when the CDR link 
is down and the buffer is filled, G3r provides the following call record handling 
options:
— Calls overwrite records (default) - warning
— Calls are blocked with a reorder tone - reorder
— Calls are rerouted to an attendant as non-CDR calls b ut are not recorded - 
attendant
NOTE:
Rerouting calls to an attendant allows the attendant to manually track 
calls. This option is only available in MIPS, G3r.
For G3i, G3vsV1/G3sV1, G3iV1, and G3i-Global, record s are always overwritten.

Set Time and Date
The system clock must be set for daylight savings time when the time changes. 
Changing the time and date ensures that CDR record s have the correct time and 
date for the record s being kept. The time and date can be changed using the 
Management Terminal.
If the time is changed while calls are in progress, the actual call durations for 
these calls are not reflected in the CDR record. A ‘‘9999’’ outputs in the “ CDR 
Duration”  field.
CDR Data Formats
This part covers two types of formats sent to the CDR output device, date record  
and call detail formats.
Date Record Format
Several formats are available for date records: one for CDRUs, one for the 
printer, and one for the TELESEER. CDR unit. The record s sent to the TELESEER 
CDR and printer contain the date only while the records sent to the CDRU 
contain time. See Table 3-20, Table 3-21, and Table 3-22.
NOTE:
The d ate format for G3V2 and later releases can either be in month/day or 
day/month format, as selected on the ‘‘System Parameters CDR’’ form. For 
G3vsV1/G3sV1, G3iV1, and G3rV1, the month/day format is used . 
G3i-Global uses the day/month format. 
						

							Feature Descriptions

For G3V2 and later releases there is an option on the ‘‘System Parameters CDR’’ 
form that is used to administer the CDR date record format. It can be in 
day/month or month/d ay format.

Call Detail Record Format
The call detail record format provides detailed information concerning an 
incoming call, an outgoing call, or an intraswitch call. Call detail records are 
generated during call processing and are sent to the CDR outp ut device in 
ASCI I.
G3vsV1/G3sV1, G3iV1, and G3i-Global support a variety of standard fixed record 
formats. G3rV1, G3V2, and  later releases support a variety of standard fixed 
record formats and a variable (customized) format.
Customized Format (G3rV1, G3V2, and later releases)
The Variable Record Format (VRF) capability,  first introduced in System 85 V4, 
provides a flexible means to incorporate new data elements in the call record. 
The VRF method allows a record to be defined in terms of its content (from a set 
of available data elements) and the position of the data elements in the record. 
This method can be used to construct the 24-word standard formats (described 
in the next section), and custom formats. Even  though the DEFINITY switches 
output the record in ASCII character representation, the terminology ‘‘word’’ is 
retained here to be compatible with the G2 defined record s.
G3rV1, G3V2, and  later releases have the same VRF c a pability as G2 in that it 
provides the flexibility to define the d ata presentation of the call record, along 
with its contents and layouts. That is, the record content, the spacing between 
the data items and the carriage return, line feed, and nulls can be defined. This 
does not require enforcing predefined data presentations on customer devices, 
but allows new devices to handle AT&T’s call detail records. This allows sup p ort  Table 3-22. Date Record Format for TELESEER 59 Character,

of any data presentation, currently provided in G2, that is different from G1, thus
