If FECN is received on the interface, a notification is sent to frame relay
equipment on other end of the PVC.
R

ACKETS WHEN OVERLOADED
If traffic congestion occurs, discard eligible (DE) packets drop.

RAGMENTATION
HRESHOLD
Defines the maximum data packet size that will be transmitted without
fragmenting the data to support voice. Table 4-1 provides suggested
values based on the PVC CIR.
