In order to prevent this, the loop L between signal line and ground is minimized, and the noise generated during the phone call is eliminated due to the noise generated by the device.

Some examples of using the present invention configured as described above are as follows.

Ping test

A. Automatic Configuration-Dynamic Host Configuration Protocol (DHCP)

Autoconfiguration automatically configures the network environment through communication with hubs on the network.

7 is a flowchart illustrating a process of automatically setting a 'ping test' by using the inspection apparatus for measuring defects on the Internet and telephone lines according to the present invention.

As shown in FIG. 7, the operation of the ping test function using the automatic setting function is as follows.

Turn on the power switch (SW) of the master module (2) and press the automatic setting button 221 (S1).

After that, the LAN cable is connected to the first connector 26 of the master module 2 (S2).

Thereafter, a destination IP address is input using the ten key button 225 (S3). Press the start / enter button 227 to correct an incorrect entry.

When the # / ping button 229 is pressed among the ten key buttons 225, the ping test is started (S4).

To stop or restart the ping transmission, press the start / enter button 227 (S5).

To return to the network configuration screen, press the # / ping button (229).

B. Manual Configuration-Static IP

To take advantage of static IP, the network environment must be set manually. Here's how the ping test function works with static IP:

3. landline phone

The landline function determines whether the telephone network is operating properly through the actual call connection. It works in a similar way to a regular phone and uses a hook switch instead of a handset to send and receive calls.

As an additional feature, a telephone line search function is supported to detect both ends of a particular line embedded in a bundle. Here's how the landline phone works:

<Wait state>

Turn on the power switch (SW) and press the PHONE mode selection button.

Connect the telephone line to the first connector 26 of the master module (2).

<Call phone>

Lift the hook switch 226 up.

Enter the telephone number using the ten key button 225.

At the end of the call, the hook switch 226 is lowered.

<Answer call>

The call reception message of the first display window 24 is checked along with the call reception tone. If the caller ID service of the service provider is registered, the caller ID is checked.

Pick up the hook switch 226 to answer the call.

At the end of the call, the hook switch 226 is lowered.

<Search phone line>

Lower the hook switch 226 to enter standby

Connect both ends of the telephone line to be searched to the first and second connectors 26 and 46 of the master module 2 and the remote module 4.

Press the start / enter button 227 to enter the telephone line search mode.

Hook switch 226 is lifted up while alternately connecting the telephone line to be searched. At this time, check the telephone tone and the buzzer sound of the master module 2 and the remote module 4.

Press the Start / Enter button to return to standby.

<How to read the measurement results of the telephone line search function>

The user can confirm through the sound whether the desired telephone line is found.
