Kind Code:

A

Abstract:

PURPOSE: To ring an incoming sound only to an objective terminal by permitting a caller to specify an extension number by a PB signal after dial-transmitting by pushing-down a telephone number.

CONSTITUTION: When an income signal is inputted from a line connection part 1, an income detection part 3 informs the income to a control part 7. When the number of times (time) becomes specified one, the control part 7 controls a line closing connection part 2 to close/connect the line, a two-four wire converting part 10 separates it into transmission and reception and a signal sending part 5 sends a sound message (or a signal sound) to the line to urge the caller to specify the extension number by the PB signal. Concerning the PB signal transmitted from the calling side, a PB signal receiver 4 transmits reception data of the PB signal to the control part 7, which selects a slave set corresponding to the specified extension number from the group of slave sets 9 to transmit the income signal from a radio transmission/reception part 8.
