Zusammenfassung: | PURPOSE: A device for detecting rupture and state information of device in radio port of WLL(Wireless Local Loop) system is provided to collect rupture and function error signals to transfer them and check the state of ACSU(Analog Common Sector Interface Unit). CONSTITUTION: A device for detecting rupture and state information of device in radio port of WLL system comprises an address decoder(10), a clock generator(20), a synchronous signal generator(30) and plural analog common sector interfaces(40). The address decoder(10) generates chip selection signals so that a CPU of RPC(Radio Port Controller) can read/write internal buffers. The clock generator(20) receives clocks from the CPU to transfer them to the analog common sector interfaces(40). The synchronous signal generator(30) generates synchronous signals so that data can be latched to the buffers by parallel/serial conversion between the CPU and the interface(40). The analog common sector interfaces(40) perform the parallel/serial conversion in accordance with the synchronous signals to be inter-worked with an analog common sector unit. |
