Abstract: A system for controlling the initiation of voting telephone calls by controlling character generators at a group of affiliated television broadcast stations through a control center which receives real-time feedback of telephone voting traffic data from polling terminals at telephone central offices and utilizes this information to regulate visual stimuli broadcast by the television station. The control center initiates polling traffic by causing associated character generators at the affiliate transmitter to produce the desired message displays across the TV screen. The control center monitors the polling call traffic at each central office until it determines that the traffic being generated has reached a level which is not within the traffic-handling capabilities of that particular central office switching machines.

Abstract: A T-carrier digital test system which actively monitors each T-carrier wire pair on a time division multiplexing basis while either live communications or test signals are on the line, and determines from the monitored data whether an incipient or hard failure of the line exists. It achieves this result by utilization of interacting devices called Scanners and Scanner Controllers. Each Scanner is housed in a repeater case and is connected to and monitors the output of each regenerative repeater in that case. The Scanner also connects to a fault line which runs in parallel to the T-Carrier wire pair and acts as the communications media and power path between several Scanners and the telecommunications facilities at each end of the cable pair.

Abstract: A dial pulse detector apparatus accurately detects the occurrence of dial pulses in the presence of adverse line conditions resulting in severe signal distortions due to inductive effects, noise and loading by other pieces of equipment. Signals greater than two different selected threshold levels are examined for, and signals less than the lower threshold are also examined for. Signals greater than the threshold levels are counted up on a time duration basis and added in a weighting arrangement. Signals less than the lower threshold are counted on a time duration basis and are subtracted from the added signals. When the combined signal counts reach a first specified count a dial pulse break signal is recognized. Signal counting is continued and when the combined signal counts reach a second specified count a dial pulse make signal is recognized, thereby completing the detection of a dial pulse.

Abstract: A data terminal utilizes a time division multiplexer to monitor traffic on up to 8000 input lines in banks of 1000 lines and converts the information in each bank from parallel to serial form as 1000 serial 112 bit parallel words, records the various kinds of event count data and usage time duration for each input line, and under interrogation by a control center transmits the accumulated data.The terminal has up to eight serial synchronously operating memory banks, one for each bank of 1000 lines, each memory bank containing an accumulating memory which counts the events as they occur and a passive memory which upon command receives data from the accumulating memory. The condition of each line is examined continuously cyclically to determine the presence or absence of specifically different particular events and the durations of such events. The accumulated data is usable directly for billing purposes when the apparatus is used to monitor telephone subscriber lines.

Abstract: Apparatus for connection to the line finder group busy signal leads of telephone office equipment to determine when each line finder group is and is not busy, make an averaging determination of the busy conditions and generate signals indicating this average condition of busy activity on the monitored lines. The apparatus includes a parallel to serial multiplexer for cyclically sequentially sampling the line finder busy signal leads, means for selecting which of the leads are to be sampled, and a divide-by-N counter settable to count a predetermined number of pulses received from the multiplexer equal to the number of leads selected for monitoring, and to generate an output signal after each receipt of such predetermined number of pulses. The timing of the apparatus is so arranged that each generated output signal directly represents a busy time of 0.1% of an hour or 3.6 seconds.
