early packet discard (EPD)
EPD is a feature that applies a more stringent discard policy to the first cell of
an AAL-5 frame than it does to subsequent cells. This reduces the number of
incomplete frames in the network and thereby increases the throughput.
EAP
See external address plan (EAP) (page 51).
EBGP
See external border gateway protocol (EBGP) (page 51).
EBR
1 See edge-based rerouting (EBR) (page 46).
2 See equivalent bit rate (EBR) (page 49)
echo cancellation
A technique in voice networking that allows for the isolation and filtering of
unwanted signal energy caused by echoes from the main transmitted signal.
ECR
See equivalent cell rate (ECR) (page 49).
edge-based rerouting (EBR)
Edge-based rerouting refers to procedures used in a PNNI network to recover
and optimize active point-to-point SVC, SVP, soft PVC, and soft PVP
connections.
