Terminal switching control apparatus

A terminal switching control apparatus comprising:

• a facsimile for executing a facsimile communication through a communication line in response to a facsimile communication start instruction input thereto and for generating a facsimile communication end signal upon completion of said facsimile communication;
• recording means for recording communication data input through said communication line in accordance with a record start instruction input thereto, and for stopping a recording operation in accordance with a record stop instruction input thereto;
• call detector means for generating a call detect signal in accordance with a calling signal input through said communication line;
• data detector means for detecting that said communication data is being input through said communication line, and for generating a data detect signal;
• and
• control means for outputting a first facsimile control signal through said communication line once during a first time period, in response to said call detect signal from said call detector means, said first time period being repeated within a second time period, for outputting said record start instruction to said recording means, for outputting said record stop instruction to said recording means upon elapse of said second time period, for outputting said record stop instruction to said recording means and said facsimile communication start instruction to said facsimile in accordance with a second facsimile control signal input through said communication line during said second time period, for outputting said record stop instruction to said recording means in response to inactivation of said data detect signal output from said data detector means during said record second time period, and for monitoring said call detect signal from said call detector means in response to one of elapse of said second time period and said facsimile communication end signal from said facsimile.

A terminal switching control apparatus comprising:

• a facsimile for executing a facsimile communication through a communication line in response to a facsimile communication start instruction input thereto, and for generating a facsimile communication end signal upon completion of said facsimile communication;
• recording means for recording communication data input through said communication line in accordance with a record start instruction input thereto, and for stopping a recording operation in accordance with a record stop instruction input thereto;
• call detector means for generating a call detect signal in accordance with a calling signal input through said communication line;
• data detector means for detecting that said communication data is being input through said communication line, and for generating a data detect signal;
• and
• control means for outputting said record start instruction to said recording means in response to said detect signal from said call detector means, for outputting said record stop signal to said recording means and said facsimile communication start instruction to said facsimile upon elapse of a first time period, and for monitoring said call detect signal from said call detector means in response to said facsimile communication end signal from said facsimile.

A terminal switching control apparatus comprising:

• a telephone for generating communication signal in response to the performance of a telephone communication through a first channel and a communication line;
• a facsimile for executing a facsimile communication through a second channel and said communication line in accordance with a facsimile communication start instruction input thereto, and for generating a facsimile communication end signal upon completion of said facsimile communication;
• recording means for recording communication data input through said communication line, in accordance with a record start instruction input thereto, and for stopping a communication data recording operation in accordance with a record stop instruction input thereto;
• channel establish means for selectively establishing one of said first channel between said communication line and said telephone, said second channel between said communication line and said facsimile, and said third channel between said communication line and said recording means, in accordance with an establish instruction input thereto;
• call detector means for generating a call detect signal in accordance with a calling signal input through said communication line;
• mode setting means for setting one of first and second modes;
• data detector means for detecting that said communication data is being input through said communication line, and for generating a data detect signal;
• and
• control means including first means for monitoring said call detect signal from said call detector means in response to one of said record stop instruction, said communication signal from said telephone, and said facsimile communication end signal from said facsimile and for determining whether said first mode or said second mode is set by said mode setting means, in response to said call detect signal from said call detector means;
• means, when it is determined by said first means that said first mode is set, for outputting a first facsimile control signal through said communication line once every first time period repeated within a second time period, for outputting said establish instruction to said channel establishment means to establish said second channel and said facsimile communication start instruction to said facsimile, in response to a second facsimile control signal input through said communication line within said second time period, and for outputting said establish instruction to said channel establishment means to establish said first channel to enable said telephone communication in response to elapse of said second time period;
• and means, when it is determined by said first means that said first mode is set, for outputting said record start instruction to said recording means and said establish instruction to said channel establishment means to establish said third channel, for outputting said first facsimile control signal through said communication line once every third time period repeated within a fourth time period, and for generating and outputting to said recording means said record stop instruction in response to elapse of said fourth time period.
