The present invention relates to a system for controlling a miscellaneous device such as a remote device associated with an exchange which handles a fixed length cell with a control field and an information field. The object of the invention is to offer a system where an exchange can control a miscellaneous device such as a remote device in accordance with the feature of the exchange. The exchange includes a call processor, a switch and a signal device. In order to control the miscellaneous device, a path is formed between the signal device and the miscellaneous device. Control information from the call processor is cellulated. The path notifies the miscellaneous device of the control information including cell via the switch to control the miscellaneous device by the exchange.
A system handling a fixed length cell having a control field and an information field, for controlling miscellaneous means connected thereto via a path on which the fixed length cell is transmitted, said system comprising a call processor and a signal device, said signal device including means for converting a control information from said call processor into a fixed length cell, said signal device notifying said miscellaneous means of the fixed length cell including said control information via said path to control said miscellaneous means.
An ATM exchange handling a fixed length cell having a control field and an information field, for controlling miscellaneous means connected thereto via ATM path on which the fixed length cell is transmitted, said ATM exchange comprising a call processor, and a signal device, said signal device converting a control information from said call processor into a fixed length cell and notifying said miscellaneous means of said fixed length cell including said control information via said ATM path to control said miscellaneous means.
A system handling a fixed length cell having a control field and an information field, for controlling a plurality of miscellaneous means each connected thereto via a path on which the fixed length cell is transmitted, said system comprising a call processor, and a signal device, said signal device converting a control information from said call processor into a fixed length cell and using the path to transmit said fixed length cell including said control information to the miscellaneous means and to control said connected miscellaneous means.
A system handling a fixed length cell having a control field and an information field, for controlling a cell process unit connected thereto via a path on which the fixed length cell is transmitted, said system comprising a call processor and a signal device, said signal device including means for converting a control information from said call processor into a fixed length cell, said signal device notifying said cell process unit of the fixed length cell including said control information via said path to control said cell process unit.
An ATM exchange handling a fixed length cell having a control field and an information field, for controlling a cell process unit connected thereto via ATM path on which the fixed length cell is transmitted, said ATM exchange comprising a call processor, and a signal device, said signal device converting a control information from said call processor into a fixed length cell and notifying said cell process unit of said fixed length cell including said control information via said ATM path to control said cell process unit.
A system handling a fixed length cell having a control field and an information field, for controlling a plurality of cell process units each connected thereto via a path on which the fixed length cell is transmitted, said system comprising a call processor, and a signal device, said signal device converting a control information from said call processor into a fixed length cell and using the path to transmit said fixed length cell including said control information to the cell process units and to control said connected cell process units.
A method of controlling a data unit, connected to a switch unit for switching a fixed length cell having a control field and an information field via a path on which the fixed length cell is transmitted, said data unit processing the fixed length cell, the method comprising the steps of:
