Abstract: An apparatus and a method for matching a base station with a terminal are provided to connect the terminal with the base station by cable when at least one of the terminal and the base station does not normally operate, thereby stably performing a connection test between the terminal and the base station. The first connector collects a signal outputted from a base station(200). The second connector collects a signal outputted from a terminal(300). A signal controller(150) converts the size of the signal collected through the first connector and provides it the second connector. The signal controller converts the size of the signal collected through the second connector and provides it the first connector. A header(140) receives matching information including at least one of frame synchronization and a frame number from the base station and transmits the matching information to the signal controller. The third connector transmits the matching information to the terminal.

Abstract: An apparatus and a method for testing a terminal are provided to shorten the development time and achieve a cost-saving effect by notifying whether or not a terminal is in a normal state in an online environment where a base station exists. A host computer(201) confirms whether or not a base station that transceives data with a terminal exists. In the case of an offline at which the base station does not exist, the host computer generates a verification signal for testing a modem state of a terminal. An offline transmission test unit(203) converts the generated verification signal into a certain format signal. The converted verification signal is provided to the terminal. In the case of an online mode where the base station exits, the state information is collected.

Abstract: PURPOSE: An AAL type conversion device in a wireless communication base station is provided to install an AAL type converter in a base station, and to simultaneously receive many channels having optional VPIs/VCIs, thereby efficiently using T1/E1 links and enabling channel expansion by expanding a CAM(Content Addressable Memory) and a DPRAM. CONSTITUTION: A CAM(35) is mapped with header information of an ATM cell, and outputs new header information. A type confirmer(31) determines whether to type-convert or bypass the inputted ATM cell. An AAL5/2 converter(32) converts a determined AAL5-type ATM cell into an AAL2-type ATM cell. A DPRAM(36) stores a packet if the AAL5-type ATM cell is not assembled to the AAL2-type ATM cell. A bypass unit(33) stores at least one ATM cell to be bypassed. A cell multiplexer(34) selectively outputs the ATM cell stored in the AAL5/2 converter(32) and the bypass unit(33).
