Abstract
A method for generating an internal clock in a radio network controller and a relevant transmission processing board. The transmission processing board comprises; a clock signal selector for extracting a clock signal from a synchronous/asynchronous line connected with a core network when said transmission processing board functions as a master transmission processing board, or for obtaining a clock signal from a clock bus of a sub-rack in which said transmission processing board is located when said transmission processing board functions as a slave transmission processing board; a phase-locked loop for generating a reference transmission clock based on the clock signal extracted or obtained by said clock signal selector; and a clock driver for transmitting the generated reference transmission clock to the clock bus of the sub-rackin which said transmission processing board is located when said transmission processing board functions as a master transmission processing board.
