ABSTRACT:
Information on the usage of memory mapped equipment in a telephone switching office can be continuously and non-invasively obtained by monitoring activity on the address, data, and control lines of the computer controlling such equipment. By counting the number of times a circuit is accessed by a computer, as determined by the detection of address, data, and control values for the circuit, equipment usage can be objectively determined. Further, a display device can be attached to an input/output port of a telephone office equipment monitor to provide a graphical representation of data obtained using the display device.
