Abstract

Un conmutador de modo de transferencia asíncrono (ATM) (20) tiene varios puertos de conmutador (24) conectados por respectivos enlaces 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 filay 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 de serviciodesde una columna de unidades de puntos de cruce. Los enlaces bidireccionales entre cada puerto de conmutador y su correspondiente unidad de fila y columnadel nucleo de conmutador transportan tanto células de servicio como células de control. Las células de distinto tamano se transportan en los enlacesbidireccionales entre el nucleo de conmutador y los puertos de conmutador. El tamano de las células de servicio es diferente al tamano de las célulasde control, y no es necesario que el tamano de célula de la célula de servicio sea uniforme. Se proporcionan distintos tipos de células de control,células de control de conexion de enlace (LCC) y células de control de sincronizacion de enlace (LSC). Las células de control de conexion de enlace (LCC)se usan por ejemplo, para leer y escribir datos eny desde los registros de control el nucleo de conmutador. Las células de control de conexion (LCC)incluyen células de dos formatos, un formato con mapas de bits (para lectura/escritura con respecto a los registros de control con mapas de bits), y unformatocodificado (que se usa para las operaciones de ingreso/egreso para algunos registros con mapas de bits así como registros sin mapas de bits).La invencion también propone a un método para operar a dicho conmutador de modo de transferencia asincronico (ATM)
