Abstract: PURPOSE: A dynamic routing method for a point to multi point call in a communication network is provided to set up a path-A satisfying a request condition of the point to multi point call, and to manage a point to multi point path table as a call identifier. Also, the dynamic routing method is provided to designate a branching point by using the path-A and a path-B having a same call identifier. CONSTITUTION: A communication network sets up a dynamic path-A transmitted to a destination exchange for a point to multi point call request(S33). The communication network retrieves a point to multi point path table, and confirms whether a path having a same call identifier exists(S34). The communication network selects an existing path-B similar to the path-A(S36). The communication network designates a branch point by using the path-A/B(S37). The communication network forms a new path by using the path-B from the exchange to the branch point, and forms a new path by using the path-A from the branch point to the destination exchange(S38). The communication network stores information on the new paths in the point to multi point path table(S39). The communication network processes a point to multi point call by using the new paths(S40). In the step'(S34)', if a path having the same call identifier does not exist, the communication network stores information on the dynamic path-A in the point to multi point path table(S41). The communication network processes the point to multi point call by using the dynamic path-A.

Abstract: PURPOSE: A method for speedily detecting a data transmission speed is provided to reduce a length of a stop bit in a data format transmitted to a UART(Universal Asynchronous Receiver Transmitter) and to insert information relating to a transmission speed of a next-transmitted data frame to the one part of the stop bit. CONSTITUTION: If source data(RX_DATA_S) is inputted to a DEMUX(Demultiplexer)(10), a start bit detector(11) detects start data in an existing inputted data frame. A data bit and a parity bit are stored in a shift register(16). A stop bit detector(12) is operated with a clock(UART_CLK) which is faster than a maximum bit speed of a data frame by 16 times. The stop bit detector(12) detects stop bit information during a 9/16 timing. A bit speed information detector(15) detects bit speed information(TX_RATE_INFO) of a next data frame during a remaining 7/16 timing. The bit speed information detector(15) immediately transmits the bit speed information(TX_RATE_INFO) to a sampling point detector(14). The bit speed information detector(15) decides a sampling point right from a next data frame start bit detected with the UART_CLK from a timer(13).
