CONFIGURE OR DELETE A TRAFFIC CONTRACT
Summary: This procedure describes the steps necessary to successfully navigate the Cellworx
Vision Graphical User Interface and create or delete a traffic contract. A traffic contract defines
the service class type (CBR, VBR, or UBR), data rate, and Quality of Service (QoS) and must be
specified for each Virtual Channel Connection (VCC) or Virtual Path Connection (VPC)
established. Multiple VCCs or VPCs may share a common traffic contract. Once a traffic
contract has been created it cannot be changed. It must be deleted and recreated.
Create a Traffic Contract
1. Access the Traffic Contract Configuration using the left mouse button by selecting New
from Create Connection DLP-708, or select Configuration, Connection, and Configure
Traffic Contract, or by using the direct selection keys, Alt+C, Alt+N then Alt+T. Refer to
Figure 709-1.
2. The Traffic Contract Configuration window appears. Refer to Figure 709-2. Enter
identification for the contract being created in the Traffic Contract Name text box.
Note: Any existing contracts are displayed in the box just below the Traffic Contract
Name box. These may be selected to configure a new contract using existing parameters.
To do this, single click on one of the contracts and enter a new name in the box above,
then select Apply at the bottom of the window.
3. Select a Service Class Type from the available classes displayed. See Table 709-1.
4. Select options for the traffic contract from available parameters per work order. Some of
these parameters will not be selectable depending on the Service Class Type selected. Refer
to Table 709-1 for selectable options for each Service Class Type.
Table 709-1. User Selectable Service Class Types and Parameters
