  • Protection architecture for virtual channel connections (VCCS) in a telecommunications network
    Patent number: 6353593
    Abstract: A method for protecting virtual channel connection (VCC) traffic in a telecommunications system includes receiving a virtual path connection (VPC) at a destination node. The virtual path connection (VPC) is received on each of a working transmission link and a protection transmission link. The virtual path connection (VPC) includes a plurality of virtual channel connections (VCCs) A protection switching status is received for the working and protection transmission links. The virtual channel connections (VCCs) are selected from the working and protection transmission links for processing by selecting the virtual path connection (VPC) from one of the working and protection links based on the protection switching status for at least one of the working and protection transmission links.
