PURPOSE:To simplify the constitution of each line control part and make an auxiliary constitution rich in flexibility possible, by providing the function, which absorbs attributes peculiar to respective lines, as a common part independently of the line control part. CONSTITUTION:Line adapters 101-103 are installed correspondingly to respective lines and are connected to line control parts 105-107 through bus 104. Line control parts 105-107 are connected to CPU111 through interface 109 and control transmission control procedures and so on as front end processors and have the same function to absorb common attributes out of those extracted from respective lines. Meanwhile, common part 30 absorbs attributes peculiar to respective lines, which are not absorbed by control parts 105-107, such as the processing dependent upon a prescribed polynomial in the cyclic code by the control from control parts 105- 107. |
