Abstract: PURPOSE: A method for connecting calls in a full electronic exchange is provided to improve call connection completing rates in an R2 exchange relay system, by making a transit exchange request retransmitting classification to perform normal call processes after receiving normal transmitting classification, without processing a digit completing signal as a call connection failure. CONSTITUTION: A method for connecting calls between an originating station and a relay station adapts an R2 signaling system as an exchange relay system. The method uses a link-by-link system as a signal transmitting system. The originating station makes a maximum value of a corresponding telephone exchange number bigger than digit numbers of an originating subscriber. If the originating station does not recognize request signals of transmissions even when the relay station requests transmission classification to the originating station, the relay station transmits again the request signals to the originating station without cutting off call processes.
