1. An apparatus for measuring peak utilization of a data transmission system as a percentage of data transfer capacity of the system wherein said system includes a plurality of sites and a switching network with each of said plurality of sites coupled to said switching network via a respective access channel to facilitate communication between sites over individual transmission circuits, said apparatus comprising:

  • a probe connected to the data transmission system for measuring utilization of an access channel and individual transmission circuits associated with that channel, and generating capacity information relating to the utilization percentage of the data transfer capacity of said access channel and each of its individual transmission circuits during successive predetermined sampling intervals, said probe including;

    a plurality of counters for maintaining said capacity information in the form of count totals, wherein each said counter is associated with a range of utilization percentages for at least one of said access channel and individual circuits and indicates a count of said sampling intervals during which the utilization percentage of said at least one of said access channel and individual circuits is in the range associated with that counter; and

    incrementing means, responsive to access channel and individual circuit utilization measurements in each sampling interval, for incrementing each counter for each sampling interval during which the utilization percentage of said at least one of said access channel and individual circuits is in the percentage range associated with that counter; and

    console means coupled to said probe for receiving said capacity information in the form of said count totals from said plurality of counters and processing said capacity information to selectively display data transfer capacity utilization for the access channel and individual circuits over a predetermined time interval.
