• and
• (g) a sending section for sending the second command data to a private branch exchange (PBX).

A format-converting device comprising:

• (a) a sending section for sending a first command data;
• (b) a receiving section for receiving a second command data from a private branch exchange (PBX);
• (c) a converting section for sending the first command data to said sending section;
• (d) a memory for storing a converting table, which brings a given command data into correspondence with a given function and stores the given command data and the given function, a telephony application programming interface (TAPI) function and a telephony service provider interface (TSPI) function;
• (e) a first calculating section for calculating the TAPI function;
• and
• (f) a second calculating section for calculating the TSPI function;
• wherein said second calculating section refers to the converting table based on the second command data, and calls the given TAPI function,
• wherein said first calculating section receives and calculates the given TAPI function, and calls the given function from said memory based on a calculated result of the given TAPI function,
• wherein said converting section then receives and calculates the given function, and supplies the first command data corresponding to the given function.

A private branch exchange (PBX) system comprising:

• (a) a control apparatus for performing a control function including a control function for an extension telephone;
• (b) a receiving section for receiving a first command data from said control apparatus;
• (c) a memory for storing a converting table, which brings the first command data into correspondence with a given function and stores the first command data and the given function, a telephony application programming interface (TAPI) function and a telephony service provider interface (TSPI) function;
• (d) a converting section for calculating the given function corresponding to the first command data of the converting table based on the first command data received;
• (e) a first calculating section for calculating the TAPI function;
• (f) a second calculating section for calculating the TSPI function;
• (g) a controller for allowing said first calculating section to calculate based on a calculated result of said converting section, and for allowing said second calculating section to calculate based on a calculated result of said first calculating section, and for producing a second command data;
• (h) a sending section for sending the second command data;
• and
• (i) a private branch exchange (PBX) for receiving the second command data.

A format-converting method comprising the steps of:

• (a) receiving a first command data;
• (b) selecting a telephony application programming interface (TAPI) function from a converting table based on the first command data, which brings the first command data into correspondence with the given TAPI function and stores the first command data and the given TAPI function, and calculating the TAPI function;
• (c) selecting a telephony service provider interface (TSPI) function based on a calculated result of the step (b);
• (d) calculating the selected TSPI function based on a result of the first command data;
• (e) producing a second command data based on a result of the step (d);
• and
• (f) sending the second command data.
