Abstract:
A method of simultaneously tracing a plurality of transmission lines from a first location to a second location, comprising the steps of:(a) synthesizing a speech signal;(b) selectively applying said speech signal at said first location to each transmission line to be traced, comprising the steps of:(i) transmitting an address of a memory location in a speech read only memory, wherein said speech read only memory is formatted and arranged to store and output distinct segments of speech;(ii) retrieving one of said speech segments from said memory location of said speech read only memory;(iii) converting said one of said speech segments to an analog output representative of said one of said speech segments; and(iv) routing said analog output to an audio channel;wherein each of said transmission lines receives a unique segment of said speech signal that differs from the segment of said speech signal applied to any other of said transmission lines;(c) detecting at said second location, said unique segment of said speech signal applied to each said transmission line.
