Abstract: PURPOSE: A unified RF(Radio Frequency) transceiver for a terminal access device of a WLL system is provided to compensate for loss of power caused by cables at inside the home by integrating an antenna with a RF transceiver module, a radio frequency interface of a terminal access device. CONSTITUTION: A unified RF(Radio Frequency) transceiver for a terminal access device of a WLL comprises the parts of: a RF device(500) that connected with an antenna(300) of a terminal device; a digital device(111 and 611), separated from a RF device(112), that process signal at a baseband part; and a base station(400 and 700) that does a receipt and transmission process on radio frequency with an interface and control lines and devices, which are connected with digital devices(111 and 611). The method brings results as follows. Cell zones of RF communication increase in number over inside the home communication, so output power gets recompensed for loss of power systematically. Output compensation cause by cable loss is not necessary, so load amount of RF is decreased, and then heat is less generated by diminished consuming amount of electric current. With loss of receipt channel power level of a subscriber access device lessened, reception sensitiveness and voice quality can be improved.

Abstract: PURPOSE: A method for processing an ISDN(Integrated Services Digital Network) user part circuit group reset(GRS) message in an exchange is provided to adaptively process the GRS message, depending on whether a specific trunk line is used in other exchange, so as to normally perform an initialization even when the exchange interworks with any other exchanges having different usage states relating to trunk lines. CONSTITUTION: An exchange confirms a state of circuit identification codes(CICs) being allocated, by depending on whether other exchange is used relating to specific trunk lines of each link, in a system initialization process. The exchange checks whether a CIC is allocated to a specific trunk line. If so, the exchange sets up ranges of circuit group reset(GRS) messages relating to a corresponding link as link units, and transmits a GRS message to the other exchange one time, then stands by a circuit group reset acknowledgement(GRA) message. If the GRA message is received one time from the other exchange, the exchange sets up the corresponding link as a normal state. If the CIC is not allocated, the exchange sets up the ranges of the GRS messages by dividing the ranges with the link units, except the specific trunk lines, and transmits the GRS messages to the other exchange as the number of dividing times, then stands by the GRA message. If GRA messages are received as the number of transmitting times relating to the GRS messages of the divided ranges, the exchange sets up the corresponding link as a normal state.
