Abstract
The present invention provides a method for fast passing through services in a SDH device including: a protection switching module compresses first pass-through time slots between adjacent protection ports to a second pass-through time slot; when an action of pass-through is triggered, the protection switching module sending the second pass-through time slot to a time slot configuration module to parse, and the time slot configuration module sending a parsing result to a time slot register to perform a process of a time slot pass-through. The present invention provides an apparatus for fast passing through services in a SDH device, including a protection switching module, a time slot configuration module and a time slot register. With the method and apparatus in the present invention, the processing time for the pass-through configuration is reduced obviously, which benefits to fast completion of protection switching and achieves fast recovery of ring protection network services.
