Abstract
A telephone call registering system which records the callers number and the number called and the code corresponding to the duration of the call, has a line connection circuit, a timing and evaluating system, a system for counting the dialling numbers pulses, and a system for the dialling character, a system for counting the pulses, a system for counting the called number pulses, a transit buffer to temporarily store the data, and an output to a printer or perforated tape, or a direct line to an evaluation device, or magnetic tape. There is also a electronic system for amplitude and time discrimination of the coding pulses.
