Chapter 8. Packet Manager

IN-BAND SEQUENCE NUMBER

All packets on this PVC will get a numbered tag so that ADTRAN IQ products can detect lost packets in the frame relay network. Turn this option ON only if there is an ADTRAN IQ-capable product on the other end of the PVC.

REMOTE FECN NOTIFICATION

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

REACT TO BECN

If BECN is received, traffic to the frame relay network is flowed off.

DROP DE PACKETS WHEN OVERLOADED

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

FRAGMENTATION THRESHOLD

Defines the maximum data packet size that will be transmitted without fragmenting the data to support voice. Table 8-1 on page 8-9 provides suggested values based on the PVC CIR.

FRAGMENTATION SIZE

Defines packet size when fragmentation is active.
