Abstract
There is provided an arrangement for the indirect impulsing of a number dialed on a telephone. The arrangement includes an impulsing mechanism which provides impulses at preset intervals to actuate a circuit completion switch. A shutter is movably mounted with respect to the impulsing mechanism to control the completion of the circuit, and is adapted to be moved upon the dialing of a number. The dial mechanism is detained at its dialed position and is prevented from returning to its normal undialed position. The circuit actuated by the circuit completion switch releases the dial to complete the standard dialing operation for each number dialed.
