[c-nsp] VOIP QoS on frame-ATM link

[Rodney Dunn]

I would suggest you take a look at:

http://www.cisco.com/en/US/tech/tk39/tk53/technologies_configuration_example09186a00800c83b3.shtml

You can attach the service policy direction to
the VC but make sure you understand the impact
of the cell overhead.
