ABSTRACT:
A traffic usage recorder is used with a telephone switching network to verify the grade of service being given by observing simultaneous traffic on groups of equipments. The recorder has a plurality of input terminals, each of which may be connected with a corresponding input device, such as a sleeve lead which may be marked with a distinctive busy potential. The busy potential indicates circuit usage. The individual sleeve leads are repeatedly scanned in sequence to detect a presence or absence of the busy potential and therefore the circuit usage prevailing at the time of scan. The data derived therefrom is processed to indicate CCS units, peg count, maximum switch usage, and a cumulative time during which the maximum usage occurs. (The term C.C.S. means one hundred seconds of call time). Periodically (such as once every hour), the processed data may be read out in any suitable manner. The traffic usage recorder verifies the statistical tables which are used to make traffic studies.
