A 7- or 10-digit call to the directory number of the public service answering point (PSAP) (where applicable) causing the E911 system (emergency 9-1-1 system) to send to the PSAP a multifrequency (MF) pulse train devoid of the caller's emergency service identification.
Industry:Telecommunications
A 64-bit parameter consisting of 56 independent bits and 8 parity bits operating in concert as a data encryption algorithm key.
Industry:Telecommunications
A 3-digit numerical country identifier that is part of the 14-digit network terminal numbering plan. Note: The data country code prescribed numerical designation further constitutes a segment of the overall 14-digit X. 121 numbering plan for an ITU-T X. 25 network.
Industry:Telecommunications
A 3-digit code within the North American numbering plan, beginning with 1, that classifies international calls as requiring either regular or special handling.
Industry:Telecommunications
A 3-digit code in the (NPA) numbering plan area (N) format, which are used as the first three digits of a 10-digit address in a North American Numbering Plan dialing sequence. Although NPA codes are normally used to the purpose of identifying specific geographical areas, certain of these NPA codes have been allocated to identify generic services or to provide access capability, and these are known as service access codes (SACs. ) The common trait, which is in contrast to an NPA code, is that SACs are nongeographic. One of the key requirements associated with an address containing a SAC is the ability to discern the appropriate carrier. To satisfy this requirement and to alleviate confusion, the term SAC is subdivided into categories that characterize their carrier identification requirements. The 3 subdivisions are ancillary carrier identification, embodied carrier identification, and external carrier identification.
Industry:Telecommunications
A 2-wire transmission line surrounded by a sheath of conductive material that protects it from the effects of external fields and confines fields produced within the line.
Industry:Telecommunications
A 1-yysecond period with one or more errored blocks. 2. A 1-second interval with one or more bit errors. Note 1: Severely errored seconds (SES) are defined as a subset of ES. Note 2: A period of loss of signal is considered as a period of errored blocks.
Industry:Telecommunications
A 1-yysecond interval in which no errored blocks are received. Note: In general, measurement is over time and is stated as a percentage, i.e., % EFS.
Industry:Telecommunications
A 1-minute interval with a BER (bit error ratio) worse than 10:6. The 1-minute intervals are derived by removing severely errored seconds from the total time and then consecutively grouping the remaining seconds into blocks of 60.
Industry:Telecommunications
A 1994-approved specification (FIPS-186-1) ruling the use of a single technique for generating signatures using the Digital Signature Algorithm.
