Facsimile terminal concentration equipment and remote operation control system therefor

A remote operation control system comprising:

• a facsimile terminal concentration equipment;
• a plurality of facsimile terminal units, connected to said facsimile terminal concentration equipment, and having means for transmitting and receiving facsimile messages;
• and
• a facsimile mail equipment remotely located with respect to said facsimile terminal concentration equipment, connected via a data channel to said facsimile terminal concentration equipment, and having means for transmitting and receiving packet data of facsimile messages through a packet network;
• wherein said facsimile terminal concentration equipment includes a memory, first means for communicating with said plurality of facsimile terminal units, storing temporarily in said memory a first facsimile message from a facsimile terminal unit, converting said first facsimile message into a first packet data, and transmitting said first packet data to said facsimile mail equipment, and second means for storing temporarily in said memory a second packet data from said facsimile mail equipment, converting said second packet data into a second facsimile message, and transmitting said second facsimile message to a facsimile terminal unit;
• and
• wherein said facsimile terminal concentration equipment includes downline loading means for transferring commands, load modules, and files other than said packet data from said facsimile mail equipment and, upline loading means for transferring commands, load modules, and files other than said packet data to said facsimile mail equipment;
• whereby a remote operation control from said facsimile mail equipment to said facsimile terminal concentration equipment may be executed through said downline loading means and said upline loading means.

A facsimile terminal concentration equipment having remote operation control and fault notification capability for use with a plurality of facsimile terminal units having means for transmitting and receiving facsimile messages, and with a remote facsimile mail equipment having means for transmitting and receiving packet data of facsimile messages through a packet network, said facsimile terminal concentration equipment comprising:

• a memory;
• means for communicating with said plurality of facsimile terminal units, storing temporarily in said memory a first facsimile message from a facsimile terminal unit, and converting said first facsimile message into packet data;
• means for transmitting said packet data to said facsimile mail equipment;
• means for storing temporarily in said memory a second packet data from said facsimile mail equipment, and converting said second packet data into a facsimile message;
• means for transmitting said facsimile message to a facsimile terminal unit;
• and
• upline loading means for supporting remote operation control at a system level by transferring commands other than said packet data to said facsimile mail equipment.
