と端末(5a)との通信が行われる。When the line connection unit (6a) detects an incoming call from the public network or the line switched network (2), it notifies the communication control unit (7) of the incoming call, and the 'Ji call control unit (7) (
In response to the incoming call detection notification from 6a), the line connection unit (6a)
The unique logical number is passed to the network connection control unit (9). The inter-network connection control unit (9) searches the terminal address storage unit (8) based on the logical number of the line connection unit (6a), retrieves the terminal address of the corresponding connection destination (the address of the terminal (5a)), and
In order to make a call to the terminal (5a), a call request is sent to the packet switching network (4) via the communication control section (11) and line connection section (12). In response to the connection completion notification from the packet switching network (4), the communication control unit (7) connects the line connection unit (6a
) accepts incoming calls. This allows data transfer between the terminal (1a) connected to the public network or circuit switched network (2) and the terminal (5a) connected to the packet switched network (4). In this data transfer enabled state, the protocol converter (10) converts the terminal (la) into
Communication is performed between the terminal (5a) and the terminal (5a).
