    • A communication system (100) comprises a processor (150), a channel memory (160), a communication line (180), a transmit connect table (146), a transmit scheduler table (144), and a program memory (148). The channel memory (160) stores channels (161) with data cells (102). The processor (150) writes channel identifiers (e.g., 1 2) into schedule fields (110-V) of the transmit scheduler table (144) and points with a pointer R and a pointer V to the schedule fields (110-V). The pointers R and V identify fields in which the processor (150) looks up for a first channel identifier. The processor (150) forwards data cells (102) from the channel memory (160) to the communication line (180) for the channel (161) corresponding to the first channel identifiers. Then, the processor (150) moves the first channel identifier to an other field and writes a second channel identifier stored in the transmit connect table (146) to the field of the first channel identifier.

    • A data communication system (2) provides a circuit and method for prioritizing and controlling the transfer of data to and from a plurality of communication channels (6-11). The data communication system defines a predetermined data threshold level (X,Y) for a data buffer (16-21) for each of the plurality of communication channels. A service request signal is generated for a one of the plurality of communication channels when a respective data buffer stores data to be transferred. The data communication system generates a threshold signal for a communication channel when a data value stored in a respective data buffer reaches a predetermined data threshold level of the data buffer. The priority levels of the communication channels which generate threshold and service request signals are then compared to determine a high priority communication channel. The highest priority communication channel is then serviced.
    • 数据通信系统(2)提供了用于优先化和控制与多个通信信道(6-11)之间的数据传送的电路和方法。 数据通信系统为多个通信信道中的每个通信信道定义数据缓冲器(16-21)的预定数据阈值电平(X,Y)。 当相应的数据缓冲器存储要传送的数据时,为多个通信信道中的一个通信信道生成服务请求信号。 当存储在相应的数据缓冲器中的数据值达到数据缓冲器的预定数据阈值电平时,数据通信系统产生通信信道的阈值信号。 然后比较产生阈值和服务请求信号的通信信道的优先级,以确定高优先级的通信信道。 然后对最高优先级的通信信道进行维护。
