Abstract: A VCG(Virtual Concatenation Group) management method in an EoS(Ethernet over SDH(Synchronous Digital Hierarchy)) transmission device is provided to manage a VCG in a software way, in order to allocate bandwidths effectively and dynamically in the EoS transmission device. A VCG management device receives VCG information set by an operator(S401,S402). The device defines the received VCG information as VCG data to generate the defined VCG data. The device sets the VCG data to a VCG channel on an SONET(Synchronous Optical Network)/SDH interface. The device manages the corresponding VCG channel by generating, modifying, and deleting data on the set VCG channel according to the VCG information set by the operator(S403-S417).

Abstract: A method for managing a failure state based on a result of protection switching operation in a transmission device is provided to enhance correctness of the failure state and enable an operator to perform property management by applying a unit failure state management mode according to the result of the protection switching operation. A control unit requests a failure state value controlled by units(412). The control unit stores the failure state value received from the controlled units(413). When a failure occurs in the controlled unit, a service is recovered by performing the protection switching operation(414). The result of the protection switching operation is determined by collecting result information for the performed protection switching operation(417). A failure level for the failure state value is selected by a determined result(419). The selected failure level is reported to an operation terminal(420).
