Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to telephone switching systems, and more particularly to ticket data access systems from digital switchboards.

[Conventional technology]

Conventionally, in this type of exchange system exchange ticket data exchange system, first, a 4-digit special number is transmitted from the exchange board of one originating station, and the receiving station uses the special number from the originating station to identify its own station. By hitting the switchboard, the switchboard of the originating station and the pseudo switchboard of the receiving station are connected via the inter-office line,
Next, inside the exchange of the 11 originating stations, the internal control circuit is switched from the central processing unit of the originating station to the communication circuit for the exchange, and the key information from the originating exchange is transferred via the inter-office line. The information is transferred to the pseudo switching board of the receiving station, and the pseudo switching board transfers it to the central processing unit of the receiving station as if it were the key information of its own station, and the central processing unit of the receiving station pseudo-exchanges the response information in response to the received key information. A response signal was transferred from the pseudo switchboard to the originating station's exchange via the inter-office line, and the originating station's exchange displayed ticket information in accordance with this information.

[Problem that the invention seeks to solve]

In the conventional switchboard ticket data access method between switchboards described above, the switchboard at the originating station and the pseudo switchboard at the terminating station are connected via an inter-office line, and internal control is performed within the switchboard at the originating station. Ticket data is exchanged by switching the circuit from the central processing unit of the originating station to the exchange telephone line, so in order to access each other, a dedicated pseudo switchboard must be set up at each station. Moreover, there is a drawback that a switching circuit is required to switch the internal control circuit of each switchboard from the central processing unit side to the telephone line side.

[Means for solving problems]

The ticket data access method for a digital switchboard according to the present invention provides five steps to the master switchboard of the switching network. a) Install a ticket database that can be accessed from the digital switchboard of the central bank exchange, store the ticket data for the digital switchboard required by all switchboards, and download the tickets from each of the digital switchboards of the master station itself and all slave stations. When accessing the database, the digital exchange and ticket database are first connected using a special number sent from the digital exchange, and then the ticket database is accessed according to the same procedure as for general call processing. After receiving the special number 1 as a response, the digital switchboard transmits data information and reads ticket data from or to the ticket database according to a predetermined data transmission control procedure. After the writing is completed and the access is completed, each station will restore its respective exchange by a call termination signal sent from the digital exchange.

In this way, all the ticket data for the digital switchboard is stored centrally in the ticket database installed at the master station.1. All exchanges in the network share this ticket database, and when necessary, by sending a special number from the digital switchboard of each exchange, a connection is established with the ticket database, making it easy to access ticket data. It is possible to achieve economical efficiency by sharing exchange memory and rationality by centralizing ticket data management.
