Partition

PBX

machine, or analog phone attached to a gateway. Examples include 1000, 24231, and so on.

Dialed Number Identification Service.

Domain Name System. System used in the Internet for translating names of network nodes into addresses.

Disengage Request.

Dual tone multifrequency. Use of two simultaneous voice-band tones for dialing (such as touch tone).

Stream of data traveling between two endpoints across a network (for example, from one LAN station to another). Multiple flows can be transmitted on a single circuit.

Capability for simultaneous data transmission from both a sending station and a receiving station.

Describes the 64-kbps PCM voice coding technique. In G.711, encoded voice is already in the correct format for digital voice delivery in the PSTN or through PBXs. Described in the ITU-T standard in its G-series recommendations.

Describes CELP compression where voice is coded into 8-kbps streams. There are two variations of this standard (G.729 and G.729 Annex A) that differ mainly in computational complexity; both provide speech quality similar to 32-kbps ADPCM. Described in the ITU-T standard in its G-series recommendations.

An ITU standard that governs H.225 session establishment and packetization. H.225 actually describes several different protocols: RAS, use of Q.931, and use of RTP.

An ITU standard that governs H.245 endpoint control.

Extension of ITU-T standard H.320 that enables videoconferencing over LANs and other packet-switched networks, as well as video over the Internet.

Capability for data transmission in only one direction at a time between a sending station and a receiving station. BSC is an example of a half- duplex protocol.

Short on-hook period usually generated by a telephone-like device during a call to indicate that the telephone is attempting to perform a dial-tone recall from a PBX. Hookflash is often used to perform call transfer.

Intra-Cluster Control Protocol

Integrated Services Digital Network. Communication protocol, offered by telephone companies, that permits telephone networks to carry data, voice, and other source traffic.

The variation in the arrival times of voice packets.

Companding technique commonly used in North America. µ-law is standardized as a 64-kbps codec in ITU-T G.711.

Media Gateway Control Protocol. A protocol for Cisco CallManager to control VoIP gateways (MGCP endpoints).

Media Termination Point.

A Partition is a logical grouping of Directory Numbers and Route Patterns with similar reachability characteristics. For simplicity, these are usually named for their characteristic, such as "NYLongDistance", "NY911", etc. When a DN or Route Pattern is placed into a certain partition, this creates a rule for who can call that device or Route List.

Private Branch Exchange. Digital or analog telephone switchboard located on the subscriber premises and used to connect private and public telephone networks.
