Abstract: PURPOSE: A subscriber access subsystem having an automatic channel assignment function in a WLL(Wireless Local Loop) system and a method for automatically assigning channels are provided to prevent the interruption of communication service by making a subscriber access subsystem recognize the position of an SLIC(Subscriber Line Interface Circuit) board or an SIO(Serial Input Output) board so that time slots can automatically be allocated. CONSTITUTION: An antenna(11) transmits and/or receives radio signals. A transmit-receive processing part(12) converts a received analog signal into a digital signal or a digital signal to send into an analog signal. A modem(13) modulates or demodulates the data transmitted or received. A switching part(14) classifies the signals supplied from the modem(13) by time slots and outputs them to a serial connection part(15) and a port connection part(16). The serial connection part(15) consists of a data conversion part(151), a DPRAM(152) and a time slot interface part(153). The data conversion part(151) converts serial data into PCM data or PCM data into serial data. The DPRAM(152) is provided for message exchange between the serial connection part(15) and a processor(17) in order to confirm the allocation of time slots. The time slot interface part(153) outputs the PCM data, inputted from the data conversion part(151), to the switching part(14) by allocating a time slot. The port connection part(16) is comprised of a signal interface processing part(161) and a CODEC(162). The signal interface processing part(161) generates a ring signal, a detects a DTMF signal, and converts an input PCM signal into a voice signal or a facsimile signal. The CODEC(162) encodes or decodes input data.

Abstract: PURPOSE: A method for transmitting and receiving a variable rate is provided to transmit a variable rate by performing a continuous transmission. CONSTITUTION: A method for transmitting and receiving a variable rate is used for direct spreading code division multiple access. A transmission information series as digital signal is modulated in a phase modulation unit(105). An orthogonal code generator(101) selects an orthogonal code generated by rate information of the transmission signal. A bit rate of the orthogonal code generated form the orthogonal code generator is two times as much as a transmitted maximum transmission rate.

Abstract: PURPOSE: A method of obtaining a buffer of contiguous memory and building a page table are provided to accesses a graphics buffer (GB) wherein the GB physical pages can be contiguous or discontiguous by a peripheral graphics device (PGD) in a computer system. CONSTITUTION: A request is received to allocate memory for a GB of a predetermined size and handle. The number of pages within the size parameter is determined based on the page size used by the computer system and the buffer size needed. A first memory block is allocated for storing the GB and locked to prevent swapping. A starting virtual address of a CPU page table (CPU/PT) is accessed and mapped to a starting logical address to allow traversal of the CPU/PT by a user application. A second memory block is allocated for building a graphics device page table (GDPT) that can be accessed by a PGD. The logical address of each GB page is sequentially accessed and the corresponding physical address of each GB page is determined from the CPU/PT. The logical and physical addresses of each GB page are stored into the GDPT. If all physical pages of the GB are contiguous, the logical and physical addresses of the GB are stored into a database indexed by a user handle. Otherwise, the starting address of the GDPT is stored into the database indexed by a user handle. Provided that all of the GB physical pages are contiguous, the PGD accesses the GB by its starting physical address. Otherwise, the PGD uses the GDPT to access the discontiguous physical pages of the GB.
