Description

Integrated test bench {Total test desk}

The present invention relates to a test bench for maintaining tracks that are subscribed to a switchboard of a telephone station, and more particularly to an integrated test bench for integrating different types of switchboards into a single test.

There are three types of exchangers in operation in Korea, and as a result, the line test benches for the maintenance of such devices are used differently depending on the type of exchanges.

The test benches that can determine the abnormality of telephone lines and telephones connected between subscribers in the telephone office are composed of dedicated test benches through test lines of electronic switchboards, inverter exchangers, and domestic TDX exchangers. The track was tested on an exchanger to which the test bench was connected.

In general, the exchanger is operated as an electronic switching system, but the track test bench connected to it determines the track for maintenance of the track by using mechanical contacts. In the case of the track test bench using such mechanical contact, it is very old due to long use and many parts are old due to repeated use.

As described above, the track test bench configured for each switchboard has a problem in that it is inconvenient to operate and a plurality of test benches should be installed because the test benches are different for each switchboard.

In addition, the number of exchanges must increase with the increase of telephone subscribers, and the increase of exchanges leads to an increase of test benches. However, there was a problem that the space of the telephone station was limited, so that the space occupied by the test bench was insufficient, and that a staff member was required to operate the test bench.

Accordingly, an object of the present invention is to provide an integrated test bench that can maintain tracks that are subscribed to a plurality of exchangers with one line tester regardless of the type of exchanger.

In order to achieve the above object, the present invention provides an input selection circuit, which is a key circuit capable of selecting and inputting a model of an exchanger, and an exchanger and a test table so as to capture a T / D line of the exchanger inputted by the input selection circuit. An exchange switch matching circuit for controlling signals so as to communicate with each other, a test connecting circuit for converting a signal of an exchange connected in the exchange matching circuit so that analog meta can enter, and a general subscriber captured by the test test connecting circuit A meta display indicating a line state of a line, a call connection circuit for making a telephone call with a general subscriber captured through a T / D line of the matched exchange, and a T / D line of the connected exchange. Howler circuit and field tester that transmits arbitrary signal to subscriber's side when test subscriber is left unattended 1KHz tone circuit that transmits random signal from test bench when manufacturing lines between snowman and test bench, and ring signal to subscriber telephone when trying to talk with any subscriber captured through the matched T / D line. A 20Hz ring circuit for giving, a dial for inputting the subscriber's telephone number to make a call with the subscriber through the call connection circuit, and a call with the fieldman or MDF man or the general subscriber at the test table through the call connection circuit. Handset circuits, MDF test and call circuits that talk to MDF man, not an exchange, and catch and test any subscriber through the test line, and telephone line circuits used to receive fieldmen or general complaints. The general subscriber connection circuit, and when a complaint is received by the handman or the general subscriber through the general subscriber connection circuit for a short time, It is characterized by an integrated test bench including a holding sound transmission circuit for generating and the primary communication path to enable the call with the fieldman or the general subscriber through the general subscriber connection circuit.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 shows an integrated test bench for maintaining a subscriber line subscribed to an exchange according to the present invention, connected to an exchange through an MDF terminal to test a line, directly conducting an MDF test, and receiving a complaint from a general subscriber. It is an integrated test bench to receive.

The integrated test bench includes an MDF terminal (1), an input selection circuit (2), an exchange matching circuit (3), a test connection circuit (5) and a meta (6), a call connection circuit (7) and a dial (8) and handset Circuit 9, howler circuit 10, 1 KHz tone circuit 11, 20 KHz ring circuit 16, MDF test call circuit 12, general subscriber circuit 13, hold sound transmitting circuit 14, Primary communication circuit 15 and the like.

In more detail, an input selection circuit (2) for selecting and connecting an exchanger to which a line to be tested is joined among various exchangers (M10CN, NO1A, 5ESS, 5ESS-200) connected to the MDF terminal (1). An exchange matching circuit (3) for controlling a signal for mutual communication between the exchange and the test table so as to capture a T / D line signal of the exchange selected by the input selection circuit (2), and the exchange matching circuit (3); The test connection circuit (5) converts the signal of the exchange captured by the signal into an analog signal, the meta (6) indicating the analog signal converted by the test connection circuit (5), and the switch matching circuit (3). A call connection circuit (7) for connecting with a general subscriber via the T / D line of the exchange captured by the switch, and the telephone number of the subscriber to call the general subscriber through the call connection circuit (7). Input A dialing circuit 9, a handset circuit 9 for inputting a subscriber's telephone number into the dial 8 to enable a call with a connected subscriber or fieldman or MDF man and a test bench operator; and the switch matching circuit 3 When the general subscriber captured through the mobile station is left the handset, the tester and the field hypothesis guy test the tracks captured through the hauler circuit 10 for transmitting arbitrary signals to the subscriber side and the switch matching circuit 3. 1KHz tone generating circuit 11 which transmits arbitrary signal at the test bench for mutual comparison and send ring signal to subscriber's telephone when talking with any subscriber captured through the matched T / D line 20 Hz ring circuit 16 for giving, MDF test and call circuit 12 for making a call with an MDF man who is not an exchanger and catching and testing any subscriber through a test line, General subscriber connection circuit 13, which is a telephone line circuit to be used when receiving, and a pending sound transmission that transmits a pending sound when it is temporarily suspended when receiving a complaint from a siteman or a general subscriber connected through the general subscriber connection circuit 13 The circuit 14 and the primary subscriber circuit 15 for making a phone call with the general subscriber or the sitemen connected through the general subscriber connection circuit 13.
