  2. Charging data record - Wikipedia

    en.wikipedia.org/wiki/Charging_Data_Record

    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.

  3. Call detail record - Wikipedia

    en.wikipedia.org/wiki/Call_detail_record

    A call detail record (CDR) is a data record produced by a telephone exchange or other telecommunications equipment that documents the details of a telephone call or other telecommunications transactions (e.g., text message) that passes through that facility or device. The record contains various attributes of the call, such as time, duration ...

  4. cdrtools - Wikipedia

    en.wikipedia.org/wiki/Cdrtools

    cdrtools (formerly known as cdrecord) is a collection of independent projects of free software/open source computer programs for CD and DVD authoring.. The project was maintained for over two decades by Jörg Schilling, who died on October 10, 2021.

  5. GPRS Tunnelling Protocol - Wikipedia

    en.wikipedia.org/wiki/GPRS_Tunnelling_Protocol

    GPRS Tunnelling Protocol (GTP) is a group of IP-based communications protocols used to carry general packet radio service (GPRS) within GSM, UMTS, LTE and 5G NR radio networks. In 3GPP architectures, GTP and Proxy Mobile IPv6 based interfaces are specified on various interface points. GTP can be decomposed into separate protocols, GTP-C, GTP-U ...

  6. Multi-gigabit transceiver - Wikipedia

    en.wikipedia.org/wiki/Multi-gigabit_transceiver

    A multi-gigabit transceiver (MGT) is a SerDes capable of operating at serial bit rates above 1 Gigabit/second. MGTs are used increasingly for data communications because they can run over longer distances, use fewer wires, and thus have lower costs than parallel interfaces with equivalent data throughput.

  7. Global title - Wikipedia

    en.wikipedia.org/wiki/Global_title

    The global title is similar in purpose on the PSTN to the host name on the Internet.In design, however, global titles are quite different. The structure is usually hierarchical, the value can be of variable length, and is not necessarily a wholly numeric value—though it often is for issues of backward compatibility and association with regular telephone numbers.

  8. CDR - Wikipedia

    en.wikipedia.org/wiki/CDR

    CDR (file format), native to CorelDRAW.cdr, the file extension used for ISO 9660 disk images created by Disk Utility in Mac OS X; Clock and data recovery, a method of synchronizing with serialized data received without a clock signal; Common Data Representation, a format used to represent data types during remote invocations on Common Object ...

  9. Mount Rainier (packet writing) - Wikipedia

    en.wikipedia.org/wiki/Mount_Rainier_(packet_writing)

    An alternative to MRW is to physically format a disc in UDF 1.5 or higher using the spared build. This is achieved by the use of specialized packet writing software, or operating systems that support UDF versions 1.5 and above. MRW capabilities overlap somewhat with that of UDF 1.5+. Information about the exact format on disc is sparse.
