Log Options
When multiple systems are logging to a shared, central log server, the combination of NAS name,
Event and Connection Id allows all the records of a report to be processed without ambiguity. (It is
crucial, in this case, that each system Name be set to a unique value; otherwise, it will be impossible
to distinguish the NAS which originated a CDR report).
A multi-channel connection is reported as a set of discrete connections to the same device (that
happen to coincide).
The record format of all CDR reports is consistent, so that all reports have a first record with
identical fields, all reports which have a second record, have identical fields in this record, etc.
The record formats for the four types of records available for event reports are as follows:
Record 1
< ConnectionId>< Event Type>< 1 OF n>< Remote Device Name>< PORT
s/l/b>
Record 2
< 2 OF n>< Direction>
available>
Record 3
< 3 OF n>
Record 4
<4 OF n>
The following fields are defined for the CDR Event Reports. The precise meaning of some fields,
timestamp for example, will vary depending upon which report the field is in. These variations are
defined further when the report contents are described.
C ALLING D IRECTION
This indicates which side initiated the connection. Possible values are “IN FROM” and “OUT TO”.
C ONNECT T IME
Refer to “Duration”.
C ONNECTION ID
This field is used to correlate all records involving a particular ISDN connection. The field is an
unsigned long hexadecimal integer. It begins at zero when the system is loaded and increments by
one to 0FFFFFFFF hex, at which point it wraps back to zero. This provides for somewhat over four
billion connections before a connection Id is re-used.
D ATA R ATE
This field indicates the data rate for a B channel. The possible values are 56 Kb, 64 Kb and 384 Kb.
Note: The data rate for modem connections is currently reported as the ISDN rate of the consumed
channel (i.e., 56KB or 64KB).
D URATION
This field reflects the time that a connection is active; it is presented in hours, minutes and seconds.
The precise meaning varies somewhat for a successful connection versus a call rejection.
