Abstract

PURPOSE:To connect a call only to a number decided in advance by interrupting a switch means when a controller cannot collate a dial number with a preset number. CONSTITUTION:When the user plugs a pocket telephone set 1 to a jack and makes dialing, a PB tone decoder section 33 converts a PB dial signal from the telephone set 1 into a binary code, takes over the information to a code conversion section 35 and takes over a digit signal to a digit signal analysis section 34. An analysis collation drive section 36 sets a connection permission number and collates whether or not the sequence and combination of a dial signal is correct based on the information from an analysis section 34 and the conversion section 35 with the collated information. When the information is correct, the connection of dial is continued and if different, the switch means 4 disconnects the telephone set 1 from the called exchange 8. Thus, the connection to the telephone line is attained by connecting the telephone set to the jack and only a predetermined number is connected.
