Abstract

Half dial pulse receiver for keyboard dialing code signals, formed by a dc keypad signal and a combination of voice frequency signals immune to the conversation characterized therein, that for lines (Tlnl) that transmit the signals dc keyboard signals, a receiver (SE), inserted in the recorder and arranged for said keyboard signal, controls, on each signal, the connection (AF1) of a normal type voice frequency receiver (TonE1) to said recorder and why for lines (Tln2) that do not transmit said dc keyboard signal a criterion (ESp) of the line is transferred to the recorder that initiates the connection (AF2) of a vocal frequency receiver with immunity to the conversation, (TonE2), to said recorder while said recorder is, captured.
