Tax pulses sent in differential mode onto a telephone subscriber line are specified as having a given voltage magnitude. The MALC system which has to produce such tax pulses feeds the line with current. Thus a closed loop is required to regulate the magnitude of the tax pulses at the 2.wire port. This regulator also allows the pulses to be cadenced and to be smoothed by introducing controlled rise and fall times. FIG. 1 summarizes what is achieved by the tax pulse regulator.
