Abstract

Abstract ISDN terminal equipment containing: a circuit switched communication unit, a packet switched communication unit, a manual starting unit (1, 5), an unsuccessful try detecting unit (2, 6), and a retrying unit (3, 7). The manual starting unit (1, 5) starts the operation of setting up a call using a predetermined one of the circuit switched communication unit and the packet switched communication unit when receiving a manual start input. The unsuccessful try detecting unit (2, 6) detects that data communication has not been successfully begun by the operation of the manual starting unit. The retrying unit (3, 7) starts the operation of setting up a call using the other of the circuit switched communication unit and the packet switched communication unit when the unsuccessful try detecting unit determines that data communication has not been successfully begun by the operation of the manual starting unit.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 147 words
ISDN terminal equipment comprising: a circuit switched communication means for carrying out data communication in accordance with a circuit switched procedure; a packet communication means for carrying out data communication in accordance with a packet switched communication procedure; a manual starting means for beginning the operation of setting up a call using a predetermined one of said circuit switched communication means and said packet switched communication means when receiving a manual start input; an unsuccessful try detecting means for detecting that data communication has not been successfully begun by the operation of said manual starting means; a retrying means for commencing the operation of setting up a call using the other of said circuit switched communication means and said packet switched communication means when said unsuccessful try detecting means detects that the data communication has not been successfully begun by the operation of said manual starting means.
Claim 2
Dependent Claim 147 words
ISDN terminal equipment comprising: a circuit switched communication means for carrying out data communication in accordance with a circuit switched procedure; a packet communication means for carrying out data communication in accordance with a packet switched communication procedure; a manual starting means for beginning the operation of setting up a call using a predetermined one of said circuit switched communication means and said packet switched communication means when receiving a manual start input; an unsuccessful try detecting means for detecting that data communication has not been successfully begun by the operation of said manual starting means; a retrying means for commencing the operation of setting up a call using the other of said circuit switched communication means and said packet switched communication means when said unsuccessful try detecting means detects that the data communication has not been successfully begun by the operation of said manual starting means.
Claim 3
Dependent Claim 45 words
ISDN terminal equipment according to claim 1, wherein said unsuccessful try detecting means determines that data communication has not been successfully begun by the operation of said manual starting means, by detecting a predetermined response state, to said operation of setting up, from the network.
Claim 4
Dependent Claim 58 words
ISDN terminal equipment according to claim 2, wherein said predetermined response state is a state of receiving a DISCONNECT signal, where the DISCONNECT signal includes a cause information element indicating "No Route to Destination", "No User Responding", or"Incompatible Destination", when said manual starting means starts the operation of setting up a call using said circuit switched communication means.
Claim 5
Dependent Claim 59 words
ISDN terminal equipment according to claim 2, wherein said predetermined response state is a state of receiving a DISCONNECT signal, where the DISCONNECT signal includes a cause information element indicating "No Route to Destination", "No User Responding", or "Incompatible Destination", when said manual setting means starts the operation of setting up a call using said packet switched communication means.
