LCAS Example 1: Capacity Increase
The bandwidth of a VCG can be increased through the LCAS' ability to
enable in-service addition of one or more members in a VCG. This
bandwidth increase is typically controlled by the user via a network
management system. The steps detailed in figure below are used to
perform this bandwidth increase.
Step 0: A member needs to be added to an existing VCG that is
LCAS-enabled. In this example, the member to add is STS-1[3,2], or
AU-3[3,2].
