Abstract
A method for implementing Automatic Protection Switching (APS) between an active board and a standby board includes detecting Synchronous Digital Hierarchy (SDH) data of main services, wherein the SDH data is received by a working port of the active board from a working line. If the SDH data received by the working port is detected as abnormal, SDH data of main services received by a protection port of the standby board is selected from a protection line, and service processing is performed for the SDH data.
