Abstract
"APARELHOS PARA CONVERSãO ENTRE SINAIS SEM FIO E SINAIS DE LINHA POR FIO E PARA MAPEAR UM SINAL SEM FIO RECEBIDO EM UMA ESTAçãO BASE DE REDE EM UM SINAL DE MODEM DE LINHA POR FIO, SISTEMA PARA CONVERTER DADOS DIGITAIS E DE VOZ DE UM SINAL DE LINHA POR FIO EM UM SINAL SEM FIO, E, PROCESSOS PARA MAPEAR UM SINAL SEM FIO EM UM SINAL DE MODEM DE LINHA POR FIO E PARA MAPEAR UM SINAL DE LINHA POR FIO EM UM SINAL SEM FIO". Um processo e aparelho são apresentados para converter um fluxo de bit celular (10) em uma forma de onda de modem de linha por fio. Um fluxo de bit celular recebido (10) é aplicado a um decodificador convolucional (34) para bits de voz classe I (12) dentro de cada quadro de bit do fluxo de bit celular (10). Os bits de voz de decodificador (16) são anexados ao quadro de bit do qual os bits decodificados são provenientes, e um marcador de quadro de 40 bit (21) é anexado a cada quadro de bit (22). Este quadro de bit modificado é transmitido a intervalos de 20 mS para um modem de linha por fio (18) para uma taxa de transmissão de bit de 19, 2 kbps. O modem de linha (38) converte o sinal em uma forma de onda e transmite o sinal para uma rede PSTN (37)."DEVICES FOR CONVERSION BETWEEN WIRELESS SIGNS AND WIRELESS LINE SIGNS AND FOR MAPPING A WIRELESS SIGNAL RECEIVED IN A NETWORK BASE STATION INTO A WIRELESS LINE MODEM SIGNAL, SYSTEM FOR CONVERTING DIGITAL AND VOICE DATA TO A SIGNAL SIGNAL. WIRELESS LINE TO A WIRELESS SIGNAL, AND PROCESSES TO MAP A WIRELESS SIGNAL TO A WIRELESS MODEM SIGNAL AND TO MAP A WIRELESS LINE SIGNAL TO A WIRELESS SIGNAL ". A method and apparatus are provided for converting a cellular bit stream (10) into a wired line modem waveform. A received cell bit stream (10) is applied to a convolutional decoder (34) for class I voice bits (12) within each bit frame of the cell bit stream (10). The decoder voice bits (16) are attached to the bit frame from which the decoded bits come, and a 40 bit frame marker (21) is attached to each bit frame (22). This modified bit frame is transmitted at 20 mS intervals to a wired line modem (18) for a bit transmission rate of 19.2 kbps. The line modem (38) converts the signal into a waveform and transmits the signal to a PSTN network (37).
