Assigned numbers are numbers working in the PSTN under an agreement such as a contract or tariff at the request of specific end users or customers for their use, or numbers not yet working but having a customer service order pending. Numbers that are not yet working and have a service order pending for more than five calendar days shall… (Read More →)

For NS/EP, the designation of priority level(s).

Authorization given by an administration for a radio station to use a radio frequency or radio frequency channel under specified conditions. [NTIA] [RR]

Common-channel signaling in which the signal channel is associated with a specific trunk group and terminates at the same pair of switches as the trunk group.
Note: In associated common-channel signaling, the signaling is usually accomplished by using the same facilities as the associated trunk group.

An Associated Location is a location (civic, geodetic or polygon) within the designated PSAP jurisdiction that may be used in wireless call scenarios to route a call toward the designated PSAP. The Associated Location is determined via a static mapping from the cell/sector ID received in incoming signaling to a routing location which, when used to query the routing database,… (Read More →)

A functional element in a NENA i3 system that uses the LoST protocol [RFC 5222] where location information (either civic address or geo-coordinates) and a Service URN serve as input to a mapping function that returns a URI used to route an emergency call toward the appropriate PSAP or responding agency based on the caller’s location.

The mode in which messages for a signaling relation involving two adjacent signaling points are conveyed over a directly interconnecting signaling link. [T1.226-1992]

1. A storage device whose storage locations are identified by their contents, or by a part of their contents, rather than by their names or positions.
Note: Associative storage can also refer to this process as well as to the device. Synonym content-addressable storage.
2. Storage that supplements another storage.

1. Grounds for confidence that an information-technology (IT) product or system meets its security objectives.
2. In INFOSEC, see information assurance.
3. A more general term than "confidence" indicating the particular measures that can be taken to establish confidence [CESG].
4. The confidence that may be held in the security provided by a Target of Evaluation[ITSEC].

A data compression technique that requires more processing capability to compress than to decompress.
Note: Asymmetric compression is typically used for the mass distribution of programs on media such as CD ROM, where significant expense can be incurred for the production and compression of data but the retrieval (or the playback) system must be low in cost. [After Silicon]
