Abstract

La presente invención se refiere a convertir corriente de señal demodulación de código de pulso (PCM) en celdas de Modo de TransferenciaAsíncrono (ATM) para conmutar y transmitir a través de un red detelecomunicaciones. Cada celda transporta una muestra PCM de hasta 48diferentes conexiones de voz, la conexiones de voz se eligen de lascorrientes de datos PCM a que tienen un destino común. Las celdas setransmiten en circuitos virtuales ATM, cada circuito transmite una celdacada 125 µs. Ventajosamente, los sistemas de transmisión ATM interconectancon sistemas PCM sin contribuir retardo apreciable y sin requerir memoriaintermedia adicional: Ventajosamente, pueden establecerse nuevastrayectorias o vías de voz la mayor parte del tiempo, empleando ranurasdisponibles en las celdas de trayectorias virtuales existentes.The present invention relates to converting pulse code demodulation (PCM) signal current into Asynchronous Transfer Mode (ATM) cells to switch and transmit over a telecommunications network. Each cell carries a PCM sample of up to 48 different voice connections, the voice connections are chosen from the PCM data streams to a common destination. Cells are transmitted on ATM virtual circuits, each circuit transmits one cell every 125 µs. Advantageously, ATM transmission systems interconnect with PCM systems without contributing appreciable delay and without requiring additional buffer memory: Advantageously, new paths or voice paths can be established most of the time, using available slots in the cells of existing virtual paths.
