In the cross section of a realizable optical fiber, ideally circular, but assumed to a first approximation to be elliptical, the average of the diameters of the smallest circle that can be circumscribed about the core-cladding boundary, and the largest circle that can be inscribed within the core-cladding boundary.

In the cross section of a realizable optical fiber, ideally circular, but in practice assumed to a first approximation to be elliptical, the average of the diameters of the smallest circle that can be circumscribed about the cladding, and the largest circle that can be inscribed within the cladding.
Industry:Telecommunications
In the DDN, a general purpose terminal device that consists of (a) all the equipment necessary to provide interface functions, perform code conversion, and transform messages on various data media, such as punched cards, magnetic tapes, and paper tapes, to electrical signals for transmission and (b) all the equipment necessary to convert received electrical signals into data stored or recorded on various data media.
Industry:Telecommunications
In the Defense Switched Network, a network-provided service in which specially conditioned interswitch trunks and access lines are used to provide secure voice, data, and facsimile transmission.
Industry:Telecommunications
In the Defense Switched Network, an access line specially conditioned, usually by providing amplitude and delay equalization, to give it characteristics suitable for handling special services, such as reducing data signaling rates (DSR) to a rate between 600 b/s and 2400 b/s.
Industry:Telecommunications
In the digital transmission of analog signals, including analog television and digital audio broadcasting (DAB,) a signal-quality effect in which the decoded analog signal is either essentially flawless or totally unusable; i.e., it exhibits no gradual degradation or improvement attributable to the presence or absence of transient phenomena such as amplitude variations that may occur during transmission. Note: The cliff effect arises from the fact that analog variations in the intensity of the detected digital have no perceptible effect on the decoded analog signal; the only criterion for declaration of a digital mark is that the digital signal level is at or exceeds the decision level. The analog signal is then recovered without perceptible degradation. If the detection threshold is not met or exceeded, there will be no digital marks declared and the analog signal represented by them cannot be decoded, and will be lost entirely.
Industry:Telecommunications
In the encoder and the feedback path of the decoder, the process that maps the core bits into a quantized difference signal. In the feed-forward path of the decoder, the process that maps the core bits and the received enhancement bits into a quantized difference signal.
Industry:Telecommunications
In the encoder, the signal path from the input of the PCM-to-uniform-PCM converter to the output of the adaptive quantizer. In the decoder, the feed-forward path is the signal path from the input of the feed-forward inverse adaptive quantizer to the output of the synchronous coding adjustment block.
Industry:Telecommunications
In the establishment of a connection or in the call setup, i.e., placement of a call, the time from the initiation of a calling signal to the receipt of a proceed-to-select signal--such as a dial tone--by the call originator.
Industry:Telecommunications
In the establishment of a connection or the placement of a call, the time from the receipt by the call originator of a proceed-to-select signal (dial tone,) until all the selection signals have been transmitted (dialing has been completed. )
