USER’S GUIDE324 CyberSWITCHEvent Report ContentsA CDR event triggers a report which can consist of one or more records. Each record correspondsto a line in the log file. This alleviates any constraints of having to fit a report in an 80 characterstring. Reports are sent to some sort of log device; either a local log file or an offnode syslog server.Each ISDN connection is assigned a connection Id to uniquely identify the connection on its system.This connection Id is presented on CDR reports so that all the records of a CDR report have thesame connection Id and can be associated, thereby the Connect and Disconnect reports for a givenconnection can be associated by their matching connection Id field.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 iscrucial, in this case, that each system Name be set to a unique value; otherwise, it will be impossibleto distinguish the NAS which originated a CDR report).A multi-channel connection is reported as a set of discrete connections to the same device (thathappen to coincide).The record format of all CDR reports is consistent, so that all reports have a first record withidentical 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>< PORTs/l/b>Record 2< 2 OF n>< Direction>available>Record 3< 3 OF n>Record 4 Name> Type><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 aredefined further when the report contents are described.CALLING D IRECTIONThis indicates which side initiated the connection. Possible values are “IN FROM” and “OUT TO”.CONNECT TIMERefer to “Duration”.CONNECTION IDThis field is used to correlate all records involving a particular ISDN connection. The field is anunsigned long hexadecimal integer. It begins at zero when the system is loaded and increments byone to 0FFFFFFFF hex, at which point it wraps back to zero. This provides for somewhat over fourbillion connections before a connection Id is re-used.
