This attribute indicates the current set of packet-wise discard
functions in effect in the receive data direction at this connection
point.
A value of ppd indicates that the Partial Packet Discard (PPD)
function is in effect. PPD may be applied at an intermediate
connecting point for a connection which is transporting frame traffic
(AAL5 at the endpoint). PPD is controlled by provisioning for
PVCs and SPVCs, and by call setup parameters in the AAL and
Traffic Descriptor Information Elements.
A value of epd indicates that the Early Packet Discard (EPD)
function is in effect at this connection endpoint. PPD and EPD are
enabled by default at a connection endpoint which is performing
AAL5 segmentation and assembly.
On ATM IP cards, all packet-wise discard functions also apply to
provisioned virtual path connections (VPCs). On CQC-based ATM
cards, packet-wise functions are not applicable for VPCs.
This attribute is not applicable for Vpts.
