| titleOfInvention | Data transfer method using L-bus in telephone network matching device of large capacity communication processing system |
| abstract | The present invention relates to a data transmission method using an L-bus in a telephone network matching device (TNAS) for transferring control information between boards constituting the telephone network matching device. The present invention provides the processor interface unit 512, the trunk interface unit 510, and the subscriber unit via an L-bus including an address / data bus, an address enable signal line, a data enable signal line, a read write signal line, and a device selection signal line. A method of transferring control data between modem connections 514 includes: a device selection step of activating a device selection signal for selecting a corresponding device; An address output step of outputting an address to the address / data bus and an address enable signal; An address latching step of latching an address from the address / data bus when the address enable signal is activated; A data output step of outputting data on the address / data bus and outputting a data enable signal after the address is latched; And a data latch step of latching data from the address / data bus when the data enable signal is activated. |
