ISDN switching apparatus

An ISDN switching apparatus for performing an ISDN local connection, comprising:

• a digital switch having a first input terminal and a second input terminal, said first and second input terminals being connected by a juncture external to said digital switch;
• a network control device performing an interface control for a public network, said network control device located between said digital switch and said public network;
• a terminal control device controlling a fixed terminal device;
• a first connection device performing a connection control of said digital switch for said terminal control device based on a connection request received by said first connection device;
• a mobile terminal control device controlling a mobile terminal;
• a second connection device performing connection control of said digital switch for said mobile terminal control device based on said connection request received by said second connection device;
• wherein, when said connection request signifies that a connection destination is said fixed terminal device, said fixed terminal device and said public network are connected by said digital switch via said first connection device and said network control device, such that a first communications path is established between said fixed terminal device and said public network,
• and when said connection request signifies that said connection destination is said mobile terminal, said public network is connected to the first input terminal by said first connection device, and the second input terminal is connected to said mobile terminal control device by said second connection device, such that a second communications path is established between said mobile terminal and said public network via said digital switch, said juncture, and the first and second input terminals.
