Abstract
A synchronous clock controller for a digital exchange accommodates installation of a plurality of office line cards. A priority encoder encodes priority information signals respectively provided from the office line cards, and generates a selection signal indicating one of the office line cards having a highest priority among the office line cards in dependence upon the priority information signals. A clock selector receives office line clock signals respectively provided from the office line cards, and outputs a selected one of the office line clock signals provided from the office line card indicated by the selection signal. A digital phase synchronizing circuit phase synchronizes the selected office line clock signal with an internal reference clock signal, and generates a reference synchronization clock signal and a bit synchronization clock signal in response to the phase synchronizing.
