CDRs are sent in GTP' messages, or saved in files and fetched with FTP protocol. Information on chargeable events includes time of call set-up, duration of the call, amount of data transferred, etc. A separate CDR is generated for each party to be charged. Entries on CDRs use a {category, usage} syntax.

The actual data chunk of the RIFF remains a Corel proprietary format. From version X4 (14) on, the CDR file is a ZIP-compressed directory of several files, among them XML files and the RIFF-structured riffdata.cdr with the familiar version signature in versions X4 (CDREvrsn) and X5 (CDRFvrsn), and a root.dat with CorelDraw X6, where the bytes 9 ...
During the summer of 1999, while the communications industry was grappling with massive growth in the use of Internet Protocol-based networks for voice and data communications, a group of industry veterans formed the IPDR Organization to begin to establish standards for use in operational and business support systems used by the communications carriers.

In computer programming, CAR (car) / k ɑːr / ⓘ and CDR (cdr) (/ ˈ k ʌ d ər / ⓘ or / ˈ k ʊ d ər / ⓘ) are primitive operations on cons cells (or "non-atomic S-expressions") introduced in the Lisp programming language. A cons cell is composed of two pointers; the car operation extracts the first pointer, and the cdr operation ...
Common Data Representation (CDR) is used to represent structured or primitive data types passed as arguments or results during remote invocations on Common Object Request Broker Architecture (CORBA) distributed objects.
