The "Traffic Contract" index card

This index card defines the channel traffic contract parameters. The possible entries depend on
the selected traffic type. The index card contains the following sections:

The index card contains the following sections:
Section
Conformance Definition:
Use MBS
Forward/Backward Traffic Des. Contract parameters for forward / backward direction
Additional action buttons for bi-directional asymmetric channels
Forward => Backward
Forward <= Backward
Forward<> Backward
1 For PVC only (SVC always require conformance definition)
2 Not always available, depends on traffic type
3 This box is only available instead of "Burst Tolerance" if "Use MBS" is activated.
4 See "General" index card; the buttons only affect the relevant index card.

Meaning
Radio button for selecting the conformance definition
- No conformance definition
- Conformance definition, selection depends on traffic type
- Information window for conformance definition
Activates / deactivates entry of maximum burst size parameter (in
cells) instead of burst tolerance.
- Peak cell rate
- Cell delay variation tolerance, referred to the peak cell rate
- Sustainable cell rate
- Burst-tolerance
- Cell delay variation tolerance, referred to the sustainable cell rate
Copies the forward parameters to the backward direction
Copies the backward parameters to the forward direction
Exchanges the forward and backward direction parameters
