Abstract: PURPOSE: A circuit for protecting an X-ray of TV is provided to simplify a circuit configuration of a voltage distributing circuit configured in an external chip so as to simplify a peripheral circuit configuration, and to suspend an operation of a cathode ray tube(CRT) when an abnormal operation is consecutively detected for a predetermined time, so as to prevent a CRT operation from being suspended, which is caused by a noise such as an impulse. CONSTITUTION: A fly back transformer(FBT)(34) has a high-voltage winding for outputting a high voltage to a cathode ray tube(CRT)(16), and a low-voltage winding for generating a low-voltage fly back pulse in proportion to the high voltage. A voltage distributor(54) distributes voltages of the FBT(34). A horizontal/vertical synchronization separator(18) separates horizontal/vertical synchronizing signals from inputted video signals, and generates a horizontal and a vertical synchronizing signal. A horizontal oscillator(20) inputs the horizontal synchronizing signal and the fly back pulse, and generates a phase-locked horizontal synchronizing signal. A horizontal blanking signal generator(22) inputs the horizontal synchronizing signal, and generates a horizontal blanking signal. A detector compares the horizontal blanking signal with the distributed voltages, and detects whether an abnormal operation is generated for a regular time. A horizontal output driver(24) responds to an output signal of the detector, and suspends the operation of the CRT(16).

Abstract: PURPOSE: A method for allocating space switch channels of a pulse code RASM(Remote Access Switching Module) is provided to allocate the space switch channels as one, even if HRC(High Rate Conversion) groups between an originating party and an incoming party are not overlapped. CONSTITUTION: A pulse code RASM(Remote Access Switching Module) decides whether originating and incoming groups are overlapped, respectively. If an overlapped part exists, the pulse code RASM calculates a sub-highway channel physically connected to HRC(High Rate Conversion) groups, on the basis of an RASM having a small copy rate between an originating and an incoming party, then identically allocates a cg_ch(calling channel) and a cd_ch(called channel). If the overlapped part does not exist, the pulse code RASM calculates the sub-highway channel connected to the HRC groups on the basis of the RASM having the small copy rate, then calculates channels in an identical location of other remaining groups. The pulse code RASM allocates the calculated channels, and connects space switches between the originating and the incoming party.
