When your frame relay service provider assigns you PVC's, they are private
unless otherwise specified.

The carrier will collect PVC's from different users and transport them over
a large pipe together, same as the carriers do with T-1 or subrate circuits.
Therefore, it is shared from that perspective, but unless someone has access
to that large pipe, the PVC's do not cross across customer boundaries.  In
other words, no other customer has access to your PVC's.

At the end points, the carrier will demux the various PVCs and route them to
the proper destinations.
