In summary, virtual concatenation enables SONET/SDH transport pipes to
be filled more efficiently with data services by grouping individual
SONET/SDH containers into a virtual high-bandwidth "link", matched to the
required service bandwidth. The following sections will provide a more
in-depth look at the inner workings of high-order and low-order VCAT
frame structures.
