Abstract

PURPOSE:To attain simple and efficient use of a service line by acquiring a trunk line port decided by a service line management table when a service line designation button is operated. CONSTITUTION:An extension telephone set 200 senses a long range line button input by a key detecting section 201 and sends an acquisition request data of a long range line 1 via a data transmission section 204. Upon the receipt of the acquisition request data of a long range line 1 from the data transmission section 104, an exchange 100 reads a setting data relating to a long range line from a storage section 103 to apply selection processing of an available trunk line port. Then an idle trunk line port is acquired from any of the trunk line ports, a dial tone is returned to the extension telephone set 200 via the trunk line port and the acquisition of the long range line is informed to the user. Thus, the user simply grasps an idle service line.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a button telephone device configured to be able to utilize a plurality of service lines.

2. Description of the Related Art In recent years, with the development of communication line networks, it has become possible to use a plurality of service lines in one telephone device. In systems where multiple service lines can be used in this way, a contract may be made with the owner of each service line so that all of the multiple office line ports provided on the main device can be connected to each service line. However, for example, in consideration of usage frequency and cost, usage efficiency is increased by limiting the usable office line ports for a certain service line. That is, in such a system, all or some of the plurality of office line ports are selectively assigned to each service line.

Conventionally, in such a system, the user used a table showing which service line was assigned to which central line port, and performed a central line port capture operation while looking at the table. In other words, the extension telephone under each user is equipped with a central line port capture button for directly specifying the central line port for each central line port, and the user must first press the central line port capture button. By operating it, you can capture the central office line port that corresponds to the target service line. Not only that, but if the central office line port can be acquired, a call is made to the secondary station corresponding to the target service line, and after the secondary station is acquired, the destination is dialed. Users had to follow the steps described above when using the service line. Furthermore, when a plurality of service lines are assigned to one office line port, the user cannot recognize which service line is being used.

Problems to be Solved by the Invention Recently, it has become possible to connect a wide variety of service lines, and the usage of service lines has also become more complex. For example, when just connecting to a service line, as mentioned above, first operate the central office line port capture button to acquire the central office line port that corresponds to the desired service line, and then connect to the secondary station corresponding to the desired service line. The user had to go through the trouble of dialing the number twice. Furthermore, even if it is possible to connect a wide variety of service lines, users must use a table or similar means to show which central office line port corresponds to which service line each time they use the service line. The problem was that it was difficult to do.

A service line management table that describes the correspondence between the office line ports that can be connected to the service line, service line designation buttons and usage status display lamps that correspond to each service line, and the usage status of each office line port and the above services. a usage status display processing means for detecting whether or not each service line is available for use based on a line management table and displaying the detected status on the usage status display lamp; A central office line port acquisition control means is provided for controlling the central office line port to be acquired as determined by the management table.

Effect With the above configuration, it is possible to automatically select and capture the central office line port according to the target service line, and the service line usage status display lamp informs the user of the service line and its usage. You can easily recognize the situation.
