Patent ID: 8548324

Claim:
A method for adjusting a service of optical synchronous digital hierarchy network, comprising: A. when a service is implemented by a space-division module and a first time-division module, a service adjusting apparatus configuring an input time-slot space-division cross path from an input service point of the space-division module to an input service point of a second time-division module and a time-division cross path inside the second time-division module for the service to form a concurrence of the service in the first time-division module and the second time-division module; and B. the service adjusting apparatus configuring an output time-slot space-division cross path from an output service point the second time-division module to an output service point of the space-division module for the service; and deleting an original cross path formed by the first time-division module so as to switch the service from the first time-division module to the second time-division module.
