Abstract
Un método para operar un conmutador de modo e transferencia asincrono (ATM) (20) que tiene varios puertos de conmutador (24) conectados por respectivosenlaces bidireccionales (27, 28) a un nucleo de conmutador (22). Conectada a cada puerto de conmutador hay una unidad de fila y columna (40) correspondiente,cada unidad de fila y columna administra la escritura de las células de servicio a una de las unidades de fila y columna (32) y la lectura de las células deservicio desde una columna de unidades de puntos de cruce. Los enlaces bidireccionales entre cada puerto de conmutador y su correspondiente unidad de fila ycolumna del nucleo de conmutador transportan tanto células de servicio como células de control. De acuerdo al método propuesto seimplementa un intercambiointeractivo de células de control para ordenar en secuencia la operacion de nucleo de conmutador. Las operaciones que particularmente dependen de la generacionde células de control incluyen etapas de transmision de células deservicio desde el nucleo de conmutador, la transmision de células de control de estado desondeo desde el nucleo de conmutador; recuperacion de los contenidos de ciertos registros de control mantenidos por el nucleo de conmutador; y procedimientosdesincronizacion. La informacion de estado de sondeo, que indica la condicion de ocupado/libre de los puntos de cruce seleccionados, se transmite en lascélulas de control de estado de sondeo. Las células de control de estado de sondeo se generan y transmiten:(1) en respuesta a una célula de control, enparticular que evoca la informacion de estado de sondeo, o bien (2) cuando se produce un cambio de ausencia/presencia (por ejemplo condicion de libre/ocupado)de una cantidad predeterminada de las unidades de puntos de control afectadas. La invencion también propone un conmutador de modo de transferencia asincronico(ATM) para llevar a la práctica dicho método.
