A dial pulse register/sender for use in a telephone system operating in time frames each consisting of a plurality of time slots. The register/sender is capable of detecting and sending supervisory signals in dial pulse format for each time slot. The register/sender includes an integrator for filtering contact bounce, a timer for detecting a change of state in the supervisory signal, a pulse counter for counting the digits received, and sender for sending supervisory signals. Each time slot has one memory location and sequentially uses common logic of the register/sender.
