Embodiment Construction
[0018] The principle block diagram of device of the present invention is as figure 1 shown, including:
[0019] Core control circuit 1: The MC68360 communication processor is the main control center, and communicates with the network management computer through the Ethernet interface circuit; the 8031 series single-chip microcomputer system is used as the executor of specific tasks, responsible for specific control of each module inside the device;
[0020] Clock synchronization circuit 2: use T7688 interface circuit to extract 2.048MHz clock from standard E1 interface, generate 32.768MHz initial clock after frequency multiplication and PLL smoothing, and then generate 16.384MHz and 8.192MHz clocks after frequency division , and frame header signals of 122nS and 61nS width. The frame header signal of the 16.384MHz clock and 61nS width is sent to the time slot interleaving circuit 4, and the frame header signal of the 8.192MHz clock and 122nS width is sent to the PCM codec a...
