PURPOSE:To reduce a trouble to other subscriber by continuing the transmission and reception of a connector as it is without stopping it when other radio telephone set of the connector in busy state is set in mistake. CONSTITUTION:When a subscriber whose call is finished places its radio telephone set 4' on a connector 2' other than the connector in pairs with the set 4' in error, live terminals 53, 33 contact and a battery 54 is charged by the connector 2'. Then a voltage drop between the live terminals 55 is detected by a comparator 60 and informed to a control circuit 52'. Then an ID code of its own set decided in advance is fed from the control circuit 52' to the connector 2'. The ID code is dissident with its own ID code set in advance, then the control circuit 31' discriminates it that a different radio telephone set 4' is placed and the transmission and reception is made continued as it is when its own equipment is in transmission and reception state. |
