Industry:Telecommunications
The material medium or structure that forms all or part of a path from one place to another for directing the transmission of energy, such as electric currents, magnetic fields, acoustic waves, or electromagnetic waves. Note: Examples of transmission lines include wires, optical fibers, coaxial cables, rectangular closed waveguides, and dielectric slabs.
Industry:Telecommunications
The material in or on which one or more characteristics of the material may be used to represent information statically or dynamically. Note: Examples of data media are films, compact optical disks, cards, magnetic disks, magnetic drums, and paper.
Industry:Telecommunications
The master clock to which time and frequency measurements for the U. S. Department of Defense are referenced, i.e., are traceable. Note 1: The U. S. Naval Observatory master clock is designated as the DOD Master Clock. Note 2: The U. S. Naval Observatory master clock is one of the two standard time and frequency references for the U. S. Government in accordance with Federal Standard 1002-A. The other standard time and frequency reference for the U. S. Government is the National Institute of Standards and Technology (NIST) master clock.
Industry:Telecommunications
The marking or designator identifying COMSEC keying material used to secure or authenticate telecommunications carrying classified or sensitive U. S. Government or U. S. Government-derived information. Note: When written in all upper case letters, CRYPTO has the meaning stated above. When written in lower case as a prefix, crypto and crypt are abbreviations for cryptographic.
Industry:Telecommunications
The mapping from one value or format to another value or format that identifies the equivalent end-target destination. An ENUM example is the mapping of an E. 164 DN to a SIP URI address, both of which identify the called party.
Industry:Telecommunications
The manner in which radio signals travel from a transmitting antenna to a receiving antenna, such as ground wave, sky wave, direct wave, ground reflection, or scatter.
Industry:Telecommunications
The mandatory one-octet field that uniquely defines the function and format of each ISDN user-part message.
Industry:Telecommunications
The maintenance of system transfer function characteristics within specified limits by modifying circuit parameters. Note: Equalization includes modification of circuit parameters, such as resistance, inductance, or capacitance.
Industry:Telecommunications
The main lobe of an antenna radiation pattern. 2. A column of light. Note: A beam may be parallel, divergent, or convergent.
