Abstract
A radio terminal station apparatus for an SDH network wherein the synchronous network construction never breaks, even when a wired transmission line is branched. In a multiplexing quality generation circuit for multiplexing and sending out quality information of a clock, the insertion direction and insertion system to multiplex the quality information are compared with the input direction and system providing the clock in the apparatus, and, in the case of the insertion system not being the system providing the clock in the apparatus and the insertion direction being opposite to the input direction of the clock in the apparatus and when the priority degree information of the system having an input direction opposite to the insertion direction is a special value defined in advance, the same quality information as the clock in the apparatus are multiplexed and sent out.
