Abstract

PURPOSE:To ensure the reset call although all called extensions are busy and thus to increase the call function by securing the replacement for an optional digit of the called extension number with an optional figure. CONSTITUTION:The circuit of the originating register forming the reset call system is constituted as follows: Dial code relays 1A-4A, 1B-4B and 1C-4C of 1-3 digits, dial number code reception confirmation relays AD, BD and CD, and figure replacement digit designation relays AR, BR and CR are provided. In addition, the following unit are provided: release confirmation relay RCK for relays AD-CD, called subscriber busy display relay SB, common control unit start relay MST and others. In such constitution, the replacement becomes possible not only for the end one digit of the called extension number but for one figure of an optional digit. Thus the reset call is possible to other departments or divisions like the reset call into the same department to increase the function.
