ATIS is the leading technical planning and standards development organization committed to the rapid development of global, market-driven standards for the information, entertainment and communications industry.
A standardized, MIME-compliant method of decoding uuencoded e-mail messages by decoding binary data that was conveyed as a character string over a character-only channel.
Industry:Telecommunications
A state in which data retains its original meaning as long as the system configuration remains unchanged, even across system reboots. However, any change to the system configuration (such as adding or deleting user IDs, and modifying the set of valid sensitivity labels) may render data non-persistent.
Industry:Telecommunications
A state in which the customer installation (CI) presents a high-resistance path at the network interface.
Industry:Telecommunications
A state that exists on a permanent virtual circuit connection when there are no alarm conditions on either the originating or terminating endpoints. The absence of alarms must be satisfied on both the channelized side and the packetized side. During the NORM state, signaling packets have their normal alarm (N/A) bit set to 0.
Industry:Telecommunications
A state variable that identifies a value for all defined file privilege flags for all privileges defined in an implementation and a value for all file privilege attributes defined in an implementation.
Industry:Telecommunications
A state where a (bidirectional or unidirectional) service is usable. Note: Each direction of a service is assumed to be in the available state unless a transition to the unavailable state is observed without a subsequent transition to the available state. In this standard the transitions between the available and unavailable states are: (a) transition to the unavailable state occurs at the beginning of 10 consecutive severely errored seconds (SES); (b) transition to the available state occurs at the beginning of 10 consecutive seconds none of which is an SES.
Industry:Telecommunications
A statement affixed to a computer output or printout that states the highest classification being processed at the time the product was produced and requires control of the product, at that level, until determination of the true classification by an authorized person. Synonym banner.
Industry:Telecommunications
A statement defining the theoretical maximum rate at which error-free digits can be transmitted over a bandwidth-limited channel in the presence of noise, usually expressed in the form C = W log2 (1 + S/N,) where C is the channel capacity in bits per second, W is the bandwidth in hertz, and S/N is the signal-to-noise ratio. Note: Error-correction codes can improve the communications performance relative to uncoded transmission, but no practical error correction coding system exists that can closely approach the theoretical performance limit given by Shannon's law.
Industry:Telecommunications
A statement of COMSEC measures and materials used to protect a given operation, system, or organization.
