Call Detail Recording Events

For switched ISDN services:

There are five ISDN CDR events: connect, disconnect, reject, system up, and verify.

A connect event occurs when the system authenticates the remote device of an ISDN connection. The time stamp for the connect event marks the time the ISDN connection was established.

A disconnect event occurs when the system disconnects a connected device. The disconnect timestamp marks the time that the decision to disconnect was made.

A reject event occurs when the system disconnects an ISDN connection for which no device was authenticated. The reject timestamp marks the time that the decision to disconnect was made.

A system up event occurs when the system is loaded. The system up event provides a visible divider in the log file between two instances of loading the system. Since the connection ID value is a counter that begins at zero when the system is loaded, it is necessary that the log file contain an indication of when the system is loaded.

A verify event is generated by issuing the cdr verify console command. This command verifies the configuration of the CDR feature. It causes a message to be sent to all configured CDR log servers. The proper logging of the message can then be inspected to verify that CDR configuration is as desired.

For Terminal Servers:

There are four terminal server events: Term Conn, Term Disc, Term Succ, Term Fail.

A Term Conn event occurs when the system identifies a call as an asynchronous terminal connection. The time stamp marks the time when this connection is identified, not when the call is actually received. Modem negotiation takes place before the time stamp and protocol identification (async terminal vs. PPP).

A Term Disc event occurs when a terminal connection disconnects prior to switching to PPP mode. This can occur as a result of a modem call disconnecting, a user level authentication failure, or a logout (in the case of terminals used to access the admin login prompt).

A term Succ event occurs when a terminal connection passes user level authentication.

A Term Fail event occurs when a terminal connection fails user level authentication.

Event Report Contents

A CDR event triggers a report which can consist of one or more records. Each record corresponds to a line in the log file. This alleviates any constraints of having to fit a report in an 80 character string. 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 the same connection Id and can be associated, thereby the Connect and Disconnect reports for a given connection can be associated by their matching connection Id field.
