DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cordless line test control system between a main unit and a cordless terminal connection device (BS) in a digital exchange having a cordless function. In recent years, with the advancement of information communication, in a connection mode between a terminal and a digital exchange, it is uncertain which radio base station, that is, a cordless terminal connection device (BS) is accommodated by the cordless terminal, that is, the physical Digital exchanges having a cordless function, in which general accommodation conditions are not uniquely determined, have been introduced and spread by companies. In this case, the cordless terminal slave unit is wirelessly accommodated in any of the plurality of cordless terminal connection devices, and each of the cordless terminal connection devices is accommodated in the digital exchange main body via the line control unit. A wired telephone is also connected to the digital exchange via another line control unit.

[0002]

2. Description of the Related Art Conventionally, when a test is performed between an exchange and a cordless terminal connection device (BS), one of a control cordless terminal connection device (BS) and a call cordless terminal connection device (BS) in a zone under test is used. All other cordless terminal connection devices (BS) are closed. In this state, by pressing the talk button of the cordless terminal (PS) in the zone, the capture of the open talk BS is confirmed. Then, the normality of the line test was confirmed by calling another telephone from the cordless terminal (PS) and making a telephone call.

[0003]

When performing a line test between an exchange and a cordless terminal connection device (BS) in the above-mentioned conventional method, a cordless terminal other than the cordless terminal connection device to be tested in the zone under test is used. It is necessary to manually close the terminal connection device from the console, and there is a problem that this operation is complicated. Further, since the other cordless terminal connection devices in the zone under test are closed, the user cannot use the closed cordless terminal connection device, which is inconvenient. Furthermore, since only one terminal in the zone under test is in the non-blocking state, when a person goes to the zone under test and makes a call from the cordless terminal to any terminal, the non-blocking state is established. Therefore, there is a problem in that it is necessary to capture the terminal and perform the test, and therefore, in order to perform the test, the person performing the test must go to the zone to be tested, which is complicated. Furthermore, it is possible to test the entire communication path from the cordless terminal to the telephone, but if a failure is detected, the failure is a radio failure between the cordless terminal and the cordless terminal connection device, or a cordless terminal. There is a problem that it cannot be distinguished whether a physical line failure occurs between the terminal connection device and the switch body.

[0004] In view of the above-mentioned problems in the prior art, an object of the present invention is to eliminate the need to block other cordless terminal connection devices when performing a test between an exchange and a cordless terminal connection device (BS). The test can be performed even if no person is present in the cordless terminal slave, and if a failure is detected, whether the failure is a wireless failure between the cordless terminal slave and the cordless terminal connection device Another object of the present invention is to provide a cordless line test control system which can be used as a criterion for discriminating whether a physical line between the cordless terminal connection device and the exchange main unit has failed.
