Title: Repeated dialling cct. - has device programmed during manual dialling which stores and retransmits individual digits
Inventor: HUTTER MANFRED DIPL ING
IPC: H04M1/272
Filed: 1974-01-11
Abstract: The device inserts different length pauses between the stored digits. Switching means check whether excessively long pauses are made between digits during original manual dialling. When they are detected, switching means extend pauses in corresponding places. The pause extensions are done within strictly specified time limits. Time interval foran extended pause is in a fixed relation to the actual pause, and follows it in steps. If the pulse train satisfies the conditions of several AND gates contained in a pass function unit it is passed to an intermediate pulse store via several OR gates. From there it is changed to a dialling information series for further transmission.
