variety of access/edge, metro, and core applications.
Typically, the VSC874 is used on a variety of line cards where it
connects directly to media access controllers (MAC), framers,
and network processing units (NPU). These line cards can
then be interconnected using either a low-cost mesh without a
switch device (‘direct mode’) or traditional central-switch
architecture (‘fabric mode’).
