利点を有する。If the terminal 12 rejects the incoming call due to the attribute mismatch factor (
Attribute B) indicates that when the exchange control unit 51 analyzes the cause and determines that it can be handled by communication via the transmission format conversion unit 52, the exchange control unit 51 performs communication from both terminals 11 and 12 to the transmission format conversion unit 52. The @exchange control unit 51 that acquires the path transmits to the terminal 12 a call setup command having the same terminal attribute information as the incoming call rejection terminal.
~A logical path is set between the subscriber line concentrator 31~time/minute multiplex transmission line 42~transmission format converter 52~subscriber line concentrator 32~terminal 12, and data communication between the terminals 11 and 12 becomes possible◇ According to the above embodiment, the exchange control unit 51 detects a rejected call due to attribute mismatch, reacquires a time slot, sets the mode to the transmission format conversion unit 52, and processes the call again to the rejected terminal. This has the advantage that a call can be set up between the terminals 11 and 12 via the transmission format converter 52, and data can be transmitted between terminals with different attributes.
