Abstract

PURPOSE:To operate the system without stopping a data exchange for loading of a program and a data and to evade effect on other subscriber terminal equipment by applying remote loading of a protocol identification, a program and a data corresponding to the protocol of a subscriber terminal equipment to the data exchange. CONSTITUTION:When a subscriber terminal equipment 6 is accommodated newly into a data exchange 6, a data exchange 3 a program and a data of a protocol 21 of a network management equipment 1 addressed to the data exchange device 6 from a control line a1 to a line control section 60 via a line control section 30, a line control section 3n-1 and a relay line b2, and the line control section 60 supplies them to a central control section 71. The central control section 71 loads the program of the protocol 21 and the data and the subscriber information corresponding to the protocol identification code of the subscriber terminal equipment T6 to the line control section 63 to which the subscriber terminal equipment T6 is connected by the subscriber information. Thus, it is not required to stop the data exchange and the transmission of other subscriber terminal equipment.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a protocol remote loading processing method [Prior Art] Conventionally, data exchange equipment has been designed to adapt the protocol of a subscriber terminal in advance to correspond to the line to which the subscriber terminal is connected. It was configured to set programs and data.

[Problem to be solved by the invention]

The conventional data exchange device described above is configured to set the program and data of the protocol of the subscriber terminal in advance, and when a new subscriber terminal with a protocol that the data exchange device does not own joins, When the protocol is changed to update an existing subscriber terminal, the data exchange device must be stopped in order to incorporate the new protocol and data controlling the protocol owned by the terminal, and the communication of other subscriber terminals must be stopped. need to be stopped.

[Means to solve the problem]

The protocol remote loading processing method of the present invention registers and changes subscriber terminals in a data exchange network composed of a plurality of data exchange devices each accommodating subscriber terminals and a network management device that controls the data exchange devices. The network management device has a wide variety of protocols, and sends the data exchange device in which the subscriber terminal is accommodated the subscriber information of the subscriber terminal, the identification of the protocol corresponding to the protocol of the subscriber terminal, and the identification of the protocol corresponding to the protocol of the subscriber terminal. It is configured to load programs and data and enable communication with subscriber terminals using a wide variety of protocols.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the protocol remote loading processing method of the present invention. In the figure, when a subscriber terminal T6 is newly accommodated in the data exchange device 6, the subscriber information and protocol identification code of the subscriber terminal T6 are transferred from the console 11 to the console control unit of the network management device 1.
and sent to the storage device control section 15 via the central control section 14, the storage device control section 15 retrieves the program and data of the protocol 21 for controlling the protocol of the subscriber terminal T6 from the storage device 2 using the protocol identification code, and stores the data. It is sent to the switching device 6 via the central control unit 14 and line control unit 13 to the control line a1. The data exchange device 3 sends the program and data of the protocol 21 addressed to the data exchange device 6 from the control line a1 to the line control unit 60 via the line control unit 30, line control unit 3n-1 trunk line b1, 60 is passed to the central control unit 71. The central control unit 71 transfers the program and data of protocol 21 corresponding to the protocol identification code of the subscriber terminal T6 and the subscriber information to the line control unit 63 to which the subscriber terminal T6 is connected based on the subscriber information. is loaded with subscriber information. Data exchange device 6
By being loaded into the line control section 63, it becomes possible to communicate with the subscriber terminal T6. Further, when a protocol is changed due to an update of the subscriber terminal T1 housed in the data exchange device 3, the new protocol identification of the subscriber terminal T1 is transmitted from the console 11 to the program of the protocol 22 and By loading the data into the line control unit 32, the data exchange device 3 can communicate without affecting the subscriber terminals T1, T2, etc. whose protocols have been changed.

〔Effect of the invention〕

As explained above, according to the present invention, a network management device is made to hold programs and data of a wide variety of protocols,
Identification of the protocol corresponding to the protocol of the subscriber terminal from the network management device to the data exchange device when a protocol is changed due to an update of the data exchange device in which the subscriber terminal is accommodated and the subscriber terminal accommodated in the data exchange device. By remotely loading the program and data of the corresponding protocol, the subscriber terminals connected to the data exchange device can be accommodated in the data exchange device without being limited to the protocol, and the protocol of existing subscriber terminals can be easily changed. Also, the data exchange equipment can be operated without stopping the data exchange equipment to accommodate a subscriber terminal with a new protocol and incorporating the program and data of the corresponding protocol, and it also affects other subscriber terminals. communication is possible because it does not affect
