ABSTRACT:
For automatically gathering the data necessary to quantify and qualify the usage of a facsimile transceiver, there is a data collecting device having a pair of electromechanical counters which are driven by separate capacitive-type pulse generators in response to a DC control current for the transceiver to register running counts corresponding to respective ones of (1) the total number of operating cycles on the transceiver, (2) the accumulated number of cycles devoted to operation of the transceiver in a transmit mode, and (3) the accumulated number of cycles devoted to operation of the transceiver in a receive mode.
