Title:
EXCHANGE SYSTEM, COMMUNICATION TERMINAL, EXCHANGE AND LINE CONNECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2011/096060
Kind Code:
A1
Abstract:
Disclosed are an exchange system, communication terminal, exchange and line connection method which can accelerate pulse speed without the erroneous determination of dialled numbers. A communication terminal (20) is provided with: an input unit (201) for a dialled number; a conversion unit (202) which converts a reference pulse number value of a dial pulse corresponding to the dialled number to a larger converted pulse number value; an oscillator (203) which generates a clock; a counter (204) which counts the clock from the oscillator (203) on the basis of the converted pulse number value; and a send circuit (205) which sends the counted dial pulse string to a line (50). An exchange (10) is provided with: a counting unit (1021) which counts the pulse in the dial pulse string when a dial pulse string is sent from the communication terminal (20); a determination unit (1022) which determines the dialled number on the basis of the counting result of the counting unit (1021); and a control unit (1023) which carries out line control corresponding to the determined dialled number.
