In order to provide such a remote safety management service to the subscriber side, the subscriber station 112 according to the service provided by the line multiple access device 103 having a modem embedded therein and providing the communication service between the telephone station and the subscriber side is provided. It must be installed in the subscriber's premises, and a general telephone line is used as a transmission medium between modems of both sides, which has some problems.

Firstly, in case of communication service using high frequency data signal, the distance of each service is deteriorated, so the service providing distance is inevitably limited. Since the modem for remote safety management service also uses high frequency data signal, the service distance of subscriber terminal service is about 4km. It must be limited.

Second, the existing telephone line network is used as a transmission medium for service, and an unspecified noise component (especially an impulse noise) exists on the telephone line network, which may cause a decrease in transmission efficiency of communication equipment.

Third, the subscriber terminal 112 is a variety of service accommodation subscriber home environment is installed.

The development of various services using telephone lines increases the types of services used at home, the connection of many service terminals according to the type of service changes the electrical characteristics of previous telephone lines, and the electromagnetic waves generated from various terminals It may also be a major factor in lowering the reception characteristic of 112).

Fourth, as a matter of service operation, the remote safety management service provider receives communication restriction due to the installation and operation of the subscriber terminal without verification of the new subscriber's home environment and the test of the hypothetical line when a new subscriber occurs despite the above problem. In the case of the subscriber, a lot of failure information is generated to increase the load on the service providing system and reduce the system reliability.

Accordingly, an object of the present invention is to check the communication status during the actual operation of the remote safety management service modem under communication restriction due to the subscriber's telephone line status and the electrical characteristics of the home. To provide a line test device.

It is another object of the present invention to provide a subscriber line test apparatus for preventing a deterioration of system reliability caused by new subscribers or subscribers in a remote safety management system and reliably serving the subscribers.
