Abstract
Apparatus implements combined packetized time-division multiplexed (TDM) streams and TDM cross connect functions. The apparatus includes an input buffer, a reassembly state machine, a frame buffer, and a segmentation state machine. The frame buffer includes multiple bins for storing cell data. The segmentation state machine retrieves information from the bins as associated with each DS0 and assembles output cells for transmitting output DS0s. The cells may be in asynchronous transfer mode (ATM) format, allowing a single ATM backplane to be used for voice signals, data signals, and combined voice/data signals. Various types of ATM cell formats are supported.
