CONSTITUTION: A method for testing a multi-channel bit error rate(BER) in an exchange, comprises the steps as follows. When a test demand of a speech path equipment of an operator or an automatic test period interrupt is detected, a state of a corresponding device to be tested is checked. When the device to be tested is positioned in respectively different subsystems, a packet for a test demand is transmitted to a corresponding device side to be tested, and a processor executing a test processing is generated in the device to be tested. When a device to be tested is in a state capable of test, whether every channel which is a test object can be occupied is decided. If capable of occupying every channel, every channel is allocated with an equal system to a real call processing system by using a call processing library, a device control signal is outputted for forming a loop between a BER test device and a device to be tested, and then a loop is formed. When a loop where every channel is allocated between the BER test device and the device to be tested, a switch path between the BER test device and the device to be tested is set up. The BER device rotates a loop by generating test data of a bit pattern. Bit pattern data rotated and supplied through a loop of a channel allocated from the device to be tested are detected and compared with a generated bit pattern data, and then a state of a switching network is decided.

Abstract: PURPOSE: An electron gun for a cathode ray tube is provided which reduces dynamic focus voltage and does not allow beam spots to be formed around the periphery portion of a screen, to improve resolution of images. CONSTITUTION: In a cathode ray tube having a cathode, a control electrode, a screen electrode, a plurality of focus electrodes constructing a four-pole lens, and a final accelerating electrode placed adjacent to the focus lens to form a main lens, holes(42) having a rectangular form, through which red, green and blue electron beams pass, are formed in a plane of a first focus electrode, from which the electron beams emit, and circular holes(44) are formed in a plane of a second focus electrode, to which the electron beams enter. The central hole(42a) through which the green electron beam passes is smaller than the holes(42b,42c) located at the both side thereof.
