Study Indication - select using the left mouse button. This indicates the usage information is to be generated for study purposes.

Remote Interface Type - select UNI or B-ICI using the left mouse button. This selection describes the type of remote interface.

11.When all of these parameters are filled in for both the originating and the destination NE, select Next , except for CES ATM VC connections in which the user selects the Apply button to complete the connection.

12.The next window appears for ATM connections and prompts the user for more information. Refer to Figure 708-6.The Connection Name and Type are displayed at the top of the window. The Traffic Contract Type needs to be selected dependent upon the type of connection selected in the previous windows. For ATM-VP connections, classes selectable are CBR (Constant Bit Rate), UBR (Unspecified Bit Rate), UBR.1, RT-VBR 1, 2, or3 (Real Time Variable Bit Rate). Or NRT-VBR 1, 2, or 3 (Non-Real Time Variable Bit Rate). For ATM-VC connections, NRT-VBR 1, 2, or 3 , or UBR , UBR.1, or CBR are selectable.

Note: The Cellworx STN system can support any ATM Forum UNI 3.1 based traffic contracts. UNI 3.1 uses QoS Classes 0 through 4 to specify the service requirements and these can be mapped to Cellworx STN Classes I, II, and Unspecified. The Cellworx STN also supports ATMF UNI 4.0 based traffic contracts. UNI 4.0 uses parameterized QoS, which can be mapped to STN classes I, II, or Unspecified based on the QoS parameter values. There are five traffic contract types (i.e. conformance definitions) for different service categories. Table 708-1shows the relationship between the traffic contract types and the QoS class assigned to it in the Cellworx STN.

13.Next select the Ingress Traffic Contract using the left mouse button. If a traffic contract is not available for the connection, double click on NEW to create a traffic contract and go to DLP-709. The traffic contract specifies the parameters that determine if the connection is actually a CBR, RT or NRT-VBR.1, VBR.2, or VBR.3, UBR, or UBR.1 connection.

14.Once traffic contract is created, it will appear in the Ingress Traffic Contract window. Select the new traffic contract via a single click using the left mouse button.
