Abstract

PURPOSE:To use every instrument and line effectively by selecting plural kind of transmitting and receiving instrument optionally and connecting multiple-line to plural public line. CONSTITUTION:In connecting operation, a line hold requesting signal from a CPU102 makes a multiple line switching unit LSU108 hold a line. A network control unit NCU101 sends a calling number information to an exchange 100 in accordance with the indication of the CPU102. As the result, a pushphone Pp or the like connected to the exchange 100 is connected. An inquiry is informed to the CPU102 by dialing through the pushphone Pp or the like. The CPU102 drives the LSU108 to connect a voice response device 105 and sends a response indication to transmit a voice message such as an input request to the remote subscriber's telephone set. The CPU102 sends a line switching controlling data to the LSU108 again and sends the response from the device 105 to the remote telephone. The LSU108 selects an FS signal transmitter 106 or the like to transmit response information to a data telephone PT or a FAX device.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a multi-line switching system used in a computer system that transmits and receives various information such as audio information, multi-frequency information, and image information via a public line.

[Technical background of the invention and its problems]

Conventionally, in computer systems that use public lines to input and output telephone voice transmitters, multi-frequency signals (PB signals) of Zossy phones, etc., each public line has a voice response device, a multi-frequency signal receiving device, etc. It held one channel each. In recent years, in addition to rotary dial telephones, it has become necessary to support new media such as data telephones and facsimiles, as well as voice recognition devices, PS signal transmission devices, facsimile signal transmission devices, etc., and the number of devices connected per public line has increased. is on the rise. However, in this type of system, the input and output of each signal is usually performed in units of seconds to minutes, so in the conventional system configuration as described above, the utilization efficiency of each device is poor, and therefore There was a waste of resources with a lot of free time.

That is, in the existing configuration, there has been a problem that resources cannot be used effectively. Furthermore, in the past, devices were fixedly assigned to each line, which caused the problem that system expansion, migration, etc. could not be easily performed.

[Purpose of the invention]

The present invention has been made in view of the above circumstances, and allows multiple types of receiving and transmitting equipment to be arbitrarily selected and connected to multiple public lines connected to a network control device. It is also an object of the present invention to provide a multi-line switching system that can effectively utilize lines to efficiently send and receive various information including audio information and image information, and that allows for easy system expansion and migration. purpose.

[Summary of the invention]

The present invention provides a network control device to which a plurality of public lines are connected;
A line switching mechanism that allocates and controls lines to the receiving and transmitting equipment under the control of the processing unit between the plurality of types of receiving and transmitting equipment placed under the control of the processing device. a line branching mechanism section that transfers the line between the line switching mechanism section and the network control device and seizes the line under the control of the processing device; a hybrid that distributes and supplies to the receiving system equipment;
A multi-line switching device comprising a transceiver unit, etc. is provided. Under the control of the processing device, the multi-line switching device arbitrarily selects the receiving system and transmitting system equipment and selectively allocates the receiving system and transmitting system equipment to any public line connected to the network control device, thereby connecting the line.
