Emission on a frequency or frequencies immediately outside the necessary bandwidth which results from the modulation process, but excluding spurious emission.
Industry:Telecommunications
Emission on a frequency or frequencies which are outside the necessary bandwidth and the level of which may be reduced without affecting the corresponding transmission of information. Spurious emissions include harmonic emissions, parasitic emissions, intermodulation products and frequency conversion products, but exclude out-of-band emissions.
Industry:Telecommunications
Emission that results in an electrical signal's being propagated into, and interfering with the proper operation of, electronic or electrical equipment. Note: The frequency range of interference emissions may include the entire electromagnetic spectrum.
Industry:Telecommunications
Enabling/disabling of a detection point by a service control function in the course of service control execution for a particular call/service attempt.
Industry:Telecommunications
Encipherment of data within or at the source end system, with the corresponding decipherment occurring only within or at the destination end system. (See also link-by-link encipherment. )
Industry:Telecommunications
Encoding in which (a) data and clock signals are combined to form a single self-synchronizing data stream, (b) one of the two bits, i.e., "0" or "1", is represented by no transition at the beginning of a pulse period and a transition in either direction at the midpoint of a pulse period, and (c) the other is represented by a transition at the beginning of a pulse period and a transition at the midpoint of the pulse period. Note: In differential Manchester encoding, if a "1" is represented by one transition, a "0" is represented by two transitions, and vice versa.
Industry:Telecommunications
Encoding in which signal significant conditions represent binary data, such as "0" and "1", and are represented as changes to succeeding values rather than with respect to a given reference. Note: An example of differential encoding is phase-shift keying (PSK) in which the information is not conveyed by the absolute phase of the signal with respect to a reference, but by the difference between phases of successive symbols, thus eliminating the requirement for a phase reference at the receiver.
Industry:Telecommunications
Encryption in which a single cryptographic device is used to encrypt all of the data in a multiplexed link.
Industry:Telecommunications
Encryption that produces ciphertext from which the original data cannot be reproduced. Note: Irreversible encryption is useful in authentication. For example, a password might be irreversibly encrypted and the resulting ciphertext stored. A password presented later would be irreversibly encrypted identically and the two strings of ciphertext compared. If they are identical, the presented password is correct. Synonyms irreversible encipherment, one-way encryption.
