The size of the electron spot on the face of a cathode ray tube. Note: The spot size is larger than the diameter of the electron beam because of the spillover of electrons into adjacent areas of the screen near the spot. The spot size is a function of the ability of the tube to focus the electron beam, as well as of the electron gun aperture. 2. In facsimile systems, the diameter of the scanning spot or the recording spot. 3. In single-mode optical fibers, the effective core diameter.
Industry:Telecommunications
The uniform lengthening of all marking signal pulse widths at the expense of the pulse widths of all spacing pulses.
Industry:Telecommunications
Weighted absolute noise power, calculated in dB referenced to 3. 16 picowatts (-85 dBm,) which is 0 dBa. Note: The use of F1A-line or HA1-receiver weighting must be indicated in parentheses as required. A one-milliwatt, 1000-Hz tone will read +85 dBa, but the same power as white noise, randomly distributed over a 3-kHz band (nominally 300 to 3300 Hz,) will read +82 dBa, due to the frequency weighting. Synonym dBrn adjusted.
Industry:Telecommunications
The table of allocation of international call sign series contained in the current edition of the International Telecommunication Union (ITU) Radio Regulations. Note: In the table of allocation, the first two characters of each call sign (whether two letters or one number and one letter, in that order) identify the nationality of the station. In certain instances where the complete alphabetical block is allocated to a single nation, the first letter is sufficient for national identity. Individual assignments are made by appropriate national assignment authorities from the national allocation.

The technology that allows for funds to be transferred securely and instantaneously by electronic means from one bank account to another.
Industry:Telecommunications
The use of telecommunication for the transmission of signals to initiate, modify or terminate functions of equipment at a distance.
Industry:Telecommunications
The transfer of digital information between two access points or reference points. Values associated with this attribute are appropriate bit rate (in circuit mode) and throughput rate (in packet mode. )
Industry:Telecommunications
The storage space that may be regarded as addressable main storage by the user of a computer system in which virtual addresses are mapped into real addresses. Note: The size of virtual storage is limited by the addressing scheme of the computer system and by the amount of auxiliary storage available, and not by the actual number of main storage locations.
Industry:Telecommunications
The validating process that includes, but is not limited to, ensuring that a telecommunications charge card has been assigned by the card issuer and that the personal identification number matches the one assigned to that account.
Industry:Telecommunications
The time interval from removal of rf energy at the receiver input until the receiver output is squelched.
