It is migrated in P6.0 to the attributes of the same name under each
ATM service category component of the AtmIf CA.
This attribute defines whether usage parameter control (UPC) is
enabled or disabled for receive traffic for Vcc and Vpc connections
for this entire AtmIf. When this attribute is set to enabled, each
provisioned connection under the interface can be individually
provisioned to enforce or ignore UPC. When this attribute is set to
disabled, UPC cannot be enabled on the receive path for any of the
connections.
