PURPOSE:To make a direct access to an office exchange from a radio terminal and to enable to connect with a subscriber terminal by grounding a switching connector not requiring a command system it the front stage of the command system. CONSTITUTION:An incoming signal from a radio terminal 1 enters through a private line 4 to a switching connector 3. In case of a trunk connection, a switching request signal is inputted from a terminal 1 to the switching connector 3. When receiving the switching request signal, the switching connector 3 changes the line to an outgoing trunk 5 and disconnects a private line trunk 6. The connector 3 uses the outgoing trunk 5 and requests the outgoing for an office exchange 11, inputting the number of a subscriber terminal 2 from a terminal 1 after the response. Thus, the direct connection with the subscriber terminal 2 can be performed without through the trunk 6, switch, control board 8, and central office 9. |
