However, on a point-to-multipoint connection there should be no traffic in the backward direction, so we define the
backward traffic descriptor with its Cell Loss Priorities set to zero (0)

In the example above, traffic descriptor six (6) will be used in the forward direction, and traffic descriptor seven (7)
will be used in the backward direction.
Use to successively create point-to-multipoint PVCs for ports B2, B3, and C1.
