Filed: 2003-09-12
Abstract: <P>PROBLEM TO BE SOLVED: To guarantee common MCR for each connection contained in a service class without using an expensive high speed operating hardware in a DSL device.  <P>SOLUTION: DSL control sections 2-1 to 2-m output DSL sync signals 22-1 to 22-m indicative of communicable state with DSL modems 6-1 to 6-m, respectively. When the state of any one of DSL sync signals 22-1 to 22-m is changed, an MCR control section 33-i calculates an MCR threshold value=1/(M×MCR) from the number of DSL sync signals M indicating communicable state and a guaranteed MCR0. Since the DSL sync signal changes the state several to several tens times per day, the expensive high speed hardware is not required for calculating the MCR threshold value. Furthermore, the MCR control section 33-i makes a decision whether the MCR0 is guaranteed based on the interval of cells being outputted from a multiplexing section 32-i and the MCR threshold value, and a priority multiplexing section 4 outputs the cell of a service class for which a decision that the MCR cannot be guaranteed preferentially is made.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
