ITU-T recommendations

In telecommunications and computer networking Abstract Syntax Notation one (ASN.1) is a standard and flexible notation that describes data structures for representing, encoding, transmitting, and decoding data. It provides a set of formal rules for describing the structure of objects that are independent of machine-specific encoding techniques and is a precise, formal notation that removes ambiguities. ...more on Wikipedia about "Abstract syntax notation one"

The allowed cell rate is the rate in cells per second at which a source device may send data in ATM networks. ...more on Wikipedia about "Allowed cell rate"

Adaptive Multi Rate - WideBand or AMR-WB is a speech coding standard developed after the AMR using same technology like ACELP. The codec provides excellent speech quality due to wider speech bandwidth of 50 - 7000 Hz compared to narrowband speech codecs which in general are optimized for POTS wireline quality of 300-3400Hz. AMR-WB is codified as G.722.2, an ITU-T standard speech codec. ...more on Wikipedia about "AMR-WB"

(ADSL) is a form of DSL, a data communications technology that enables faster data transmission over copper telephone lines than a conventional modem can provide. ...more on Wikipedia about "Asymmetric Digital Subscriber Line"

Asynchronous Transfer Mode, or ATM for short, is a cell relay network protocol which encodes data traffic into small fixed-sized (53 byte; 48 bytes of data and 5 bytes of header information) cells instead of variable sized packets as in packet-switched networks (such as the Internet Protocol or Ethernet). ...more on Wikipedia about "Asynchronous Transfer Mode"

(ATM Adaptation Layers) *AAL Type 1 supports constant bit rate (CBR), synchronous, connection oriented traffic. Examples include T1 (DS1), E1, and x64 kbit/s emulation. ...more on Wikipedia about "ATM Adaptation Layers"

Basic encoding rules (BER) are ASN.1 encoding rules for producing self-identifying and self-delimiting transfer syntax for data structures described in ASN.1 notations. ...more on Wikipedia about "Basic encoding rules"

In the 1980s the telecommunications industry conceived that digital services would follow much the same pattern as voice services, and conceived a grandiose vision of end-to-end circuit switched services, known as the Broadband Integrated Services Digital Network (B-ISDN). This was conceived in the 1990s as a logical extension of the end-to-end circuit switched data service, ISDN. ...more on Wikipedia about "Broadband Integrated Services Digital Network"

Canonical encoding rules (CER) are a restricted variant of basic encoding rules for producing unequivocal transfer syntax for data structures described by ASN.1. ...more on Wikipedia about "Canonical encoding rules"

In computing, CHILL, (an acronym for CCITT High Level Language), is a procedural programming language designed for use in telecommunications switches (ie, the hardware used inside telephone exchanges). ...more on Wikipedia about "CHILL"

CLNS is an abbreviation of Connectionless Network Service. ...more on Wikipedia about "CLNS"

Common Management Information Protocol (CMIP) is a protocol for network management, it defines the communication between network management applications and management agents. CMIP is based on the Open Systems Interconnection (OSI) model and is part of the ITU-T X.700 series of recommendations. ...more on Wikipedia about "Common management interface protocol"

DER or Distinguished Encoding Rules is a method for encoding a data object, such as an X.509 certificate, to be digitally signed or to have its signature verified. ...more on Wikipedia about "Distinguished encoding rules"

ITU-T Recommendation E.123, or the Notation for national and international telephone numbers Recommendation E.123 defines a standard way to write telephone numbers, e-mail addresses, and web addresses. It recommends the following formats (when dialling the area code is optional for local calling): ...more on Wikipedia about "E.123"

E.164 is an ITU-T recommendation which defines the international public telecommunication numbering plan used in the PSTN and some other data networks. It also defines the format of telephone numbers. E.164 numbers can have a maximum of 15 digits and are usually written with a + prefix. To actually dial such numbers from a normal fixed line phone the appropriate international call prefix must be used. ...more on Wikipedia about "E.164"

E.214 is a numbering plan used for delivering mobility management related messages in GSM networks. The E.214 number is derived from the IMSI E.214 numbers are composed of two parts. The first, the E.164 part, is made up of a country code followed by the network code. The second part of the number is made from the MSIN part of the IMSI which identifies an individual subscriber. For more details on the derivation of the E.214 number from the IMSI, see the article about the IMSI. ...more on Wikipedia about "E.214"

Fax (short for facsimile - from Latin "fac simile", "make similar", i.e. "make a copy" - or telefacsimile) is a telecommunications technology used to transfer copies of documents, especially using affordable devices operating over the telephone network. The words telecopy and telefax are also used as synonyms. ...more on Wikipedia about "Fax"

FTAM, an ISO 8571 standard, is an OSI Application layer protocol for File Transfer Access and Management. ...more on Wikipedia about "FTAM"

Symmetric high-speed digital subscriber line (SHDSL) is a telecommunications technology for DSL subscriber lines. It describes a transmission method for signals on copper pair lines, being mostly used in Access networks to connect subscribers to Telephone exchanges or POP Access Points. ...more on Wikipedia about "G. Symmetric High-speed Digital Subscriber Line"

G.114 is an ITU recommendation that addresses acceptable delays for voice application, is oriented to national telecommunications and is more stringent that whas is normally applied in private voice networks. ...more on Wikipedia about "G.114"

G.703 is a ITU-T standard for transmitting voice or data over digital carriers such as T1 and E1. G.703 provides the specifications for pulse code modulation (PCM). ...more on Wikipedia about "G.703"

G.711 is an ITU-T standard for audio companding. It is primarily used in telephony. The standard was released for usage in 1972. ...more on Wikipedia about "G.711"

G.722 is a ITU-T standard wideband speech codec operating at 32-64 kbit/s. Technology of the codec is based on split band ADPCM. ...more on Wikipedia about "G.722"

G.722.1 is an ITU-T standard audio codec meant for low bit rate audio coding below 64 kbit/s. It is based on Polycom's SIREN codec. ...more on Wikipedia about "G.722.1"

G.723.1 is an audio codec for voice that compresses voice audio in chunks of 30 milliseconds. A look-ahead of 7.5 ms duration is also used. Music or tones such as DTMF or fax tones cannot be transported reliably with this CODEC, and thus some other method such as G.711 or out-of-band methods should be used to transport these signals. ...more on Wikipedia about "G.723.1" Who is http://www.shortopedia.com?
