Description

Test Verification System Using Central Operation System of Station Test Control between Stations

The present invention relates to a track test control between stations between stations (Trunk Test Control: hereinafter abbreviated as TTC), in particular using a centralized operation system (Centralized Automatic Reporting On Trunk, hereinafter abbreviated as CAROT) of the test function The present invention relates to a test verification apparatus using a centralized operation system of track test control between Koreas so that verification can be implemented.

In general, the TTC is a hardware block for measuring the transmission characteristics of the inter-station lines in order to improve the line quality of the inter-station line and provide high quality service, and abbreviated to the Central Control Subsystem (hereinafter referred to as CCS). The test is performed at the request of the Interconnection Network Subsystem (hereinafter abbreviated as INS) & CCS Maintenance Processor (hereinafter abbreviated as ICMP) or under the control of CAROT.

It consists of Peripheral Processor Hardware Block (abbreviated as PPH), which is a hardware block of ICMP, a processor that controls TTC, and INS & CCS maintenance interface block (hereinafter abbreviated as ICMI), which is a software block. In addition, test is performed on the line between the stations under test according to the mode data and the command data received through the TD-BUS.

When the measurement or the operation is completed according to the request of ICMP, the result is transmitted to ICMP. This is done by informing the data transmission to ICMP using the INT line of TD-BUS, and then performing the read operation by ICMP. This is going on.

Alternatively, when requesting the code 105 test from the CAROT through the control port, the TTC requests the inter-measured line to be occupied by ICMP according to the inter-measuring line information transmitted from the CAROT, and the Far End Responder of the power station as the test port. Responder (hereinafter abbreviated as FER)), then executes code 105 test.

The TTC transmits a performance command and a result to the CAROT in a frequency shift keying method through a control port connected to the CAROT and the VF line.

The interrelationship between the TTC and the hardware of ICMP and other blocks is as follows.

Firstly, a general subscriber line for occupying the line between the analog subscriber interface block and the station under test and for testing is connected to the test port of the TTC.

In addition, a general subscriber line is also connected for a test call from a large station when the CAROT port for transmitting and receiving the control command and the result data and the TTC operate in the FER during the code 105 matching test.

Second, in order to perform the digital characteristic test function with the time switch, the TTC matches the time switch, so that the bit error rate test by virtual random data can be performed on any measured trunk in the system.

Third, TTC is controlled by ICMP by combining ICMP composed of PPH and TD-BUS, and the data is composed of serial method of 1 byte unit, and the operation of TTC is determined according to the contents of received data. The result data is transmitted to ICMP by the polling method.

The CMP provides a synchronous clock for selecting a transmission and reception mode and a frequency signal indicating the start of data, and the TTC receives and translates it, and then enables an RDY signal informing that the command data and the result data are ready for transmission and reception.

The RDY signal is detected by the ICMP, and data transmission and reception are performed. When the transmission and reception of data is completed, the RDY signal is disabled to indicate completion of transmission and reception of data.

In addition, when ICMP requests the alarm status for each board and cable in TTC, the alarm status is transmitted to ICMP through TD-BUS's direct alarm port and TD-BUS communication.

The test verification apparatus using the CAROT of the conventional TTC transfers a command to the TTC to a device in which the CAROT device makes a call connection using the subscriber line for interworking with the TTC, and the received TTC receives the result value after performing the test. It performs the function verification by connecting two lines of transmission / reception directly to TTC by using the INTROGATOR equipment internally to perform the function of CAROT, so it is unreliable in hardware and debug in case of error There was a problem that the king is not easy.

The present invention has been made to solve such a problem, and its purpose is to test the code 105 test function by the centralized operation system among the functions of the inter-station line test control block that tests the inter-station line between exchanges. To provide a test verification apparatus using a centralized control system of control.

The present invention for achieving the above object relates to a test verification apparatus using a centralized operation system of inter-station line test control, which is measured according to the inter-station line information when the test request for the code of the internal control port according to the test verification A centralized operation system unit for requesting line occupation between stations and transmitting subscriber number of centralized operation system and centralized operation system test data so as to perform a test on a code; A test jig board unit for receiving the subscriber number and the test data from the centralized operating system unit, transmitting the ring back tone stored in the internal SRAM to the centralized operating system unit, and writing the subscriber number and the test data to the internal memory; ; A control board unit for requesting operation by far and responsiveness of code testing by the centralized operation system after reading the subscriber number and the command corresponding to the test data; An inter-station line test control unit is provided to the centralized operation system unit to transmit the response tone corresponding to the operation preparation completion and the response tone corresponding to the operation request from the control board to the far and resforce of the code test.
