digital milliwatt
In digital telephony, a test signal consisting of eight 8-bit words corresponding to one cycle of a sinusoidal signal approximately 1 kHz in frequency and one milliwatt, rms, in power. Note 1: The digital milliwatt is stored in ROM. A continuous signal of arbitrary length, i.e., an indefinite number of cycles, may be realized by continually reading out and concatenating the stored information into a data stream to be converted into analog form. Note 2: The digital milliwatt is used in lieu of separate test equipment. It has the advantage of being tied in frequency and amplitude to the relatively stable digital clock signal and power (voltage) supply, respectively, that are used by the digital channel bank. 2. A digital signal that is the coded representation of a 0-dBm, 1000-Hertz sine wave. [47CFR]
