    摘要: The invention comprises a time slot interchanger and method for multiplexing ISDN D-channel signals into multiplexed signals in a digital communications terminal. The method comprises receiving a frame of communication signals wherein some of the communication signals represent ISDN D-channel signals wherein each ISDN D-channel signal is represented by a first number of data bits and a second number of other bits. A first copy of the frame of communication signals is stored in a first memory while a second copy of the frame of communication signals is stored in a second memory during a first frame period. During a second frame period, at least some of the stored communication signals are retrieved from the first memory and at least some of the stored communication signals are retrieved from the second memory. Multiplexed signals are then assembled wherein at least one multiplexed signal comprises a multiplexed combination of the data bits of ISDN D-channel signals retrieved from the first and second memories.

    摘要: The invention comprises a time slot interchanger and method for multiplexing ISDN D-channel signals into multiplexed signals in a digital communications terminal. One method comprises receiving a frame of communication signals wherein some of the communication signals represent ISDN D-channel signals wherein each ISDN D-channel signal is represented by a first number of data bits and a second number of other bits. A copy of the frame of communication signals is stored in each of a first, second, third and fourth memory during a first frame period. At least some of the stored communication signals are retrieved from the first, second, third, and fourth memories during a second frame period. Multiplexed signals are then assembled wherein at least one multiplexed signal comprises a multiplexed combination of the data bits of ISDN D-channel signals retrieved from at least two of the first, second, third, and fourth memories.

    摘要: The invention comprises a time slot interchanger and method for multiplexing ISDN D-channel signals into multiplexed signals in a digital communications terminal. One method comprises receiving a frame of communication signals wherein some of the communication signals represent ISDN D-channel signals wherein each ISDN D-channel signal is represented by a first number of data bits and a second number of other bits. The first number of data bits are stored in one of four memories--a first memory, second memory, third memory or fourth memory. The data bits are stored during a first frame period. Multiplexed signals are then assembled wherein a multiplexed signal comprises a multiplexed combination of the data bits of ISDN D-channel signals retrieved from the frame of communications signals. The multiplexed signals are assembled by storing the data bits of at least two ISDN D-channel signals, each set of data bits stored at the same memory address but in a separate one of the first, second, third or fourth memories.
