Provisioning Private Line Services

This chapter provides information about provisioning Private Line (CBR) services.

Overview

A CBR data service is similar to a voice service. It requires a fixed amount of bandwidth and low cell loss and has strict delay requirements.

Creating CBR Service Object Profiles

You can create Service object profiles for the various types of CBR services. When you use a Service object profile CPC uses the values that you have specified in the profile to create the service. Profiles provide an easy way to store information about the various types of CBR services that you will be provisioning.

Figure 15-1 CBR Service Profile Object Viewer.

Figure 15-1: CBR Service Profile Object Viewer

The attributes for which you can provide values in the CBR Service object profile are outlined in the Table 15-1 below.

Creating a CBR Service

Step 1 Click the Tree Viewer button on the toolbar.

Step 2 Double-click the Service Application folder to open it.

Step 3 Double-click the Private Line Service Application folder to open it.

Step 4 Click the CBR Service folder to highlight it.

Step 5 Click the Subset Viewer button on the toolbar.

Step 6 Click to highlight an empty cell in the CBR Service Subset Viewer. Enter the required attribute values and specify a name for a new Service. The required values are:

A Endpoint and Z Endpoint--You can enter a valid A and Z Endpoint or select from a list of all valid endpoints by double-clicking to open the Network folder, Node folder, then the Port folder on the tree viewer.

: From the Port list, click to highlight the A Endpoint or Z Endpoint, and fill in the endpoints using the copy and paste commands from the Edit menu.

Note When creating CBR Services, the Private Line Service Application checks that both endpoints are structured or unstructured. If the endpoints are unstructured, the interface must be the same (DS1, DS3, etc) and the port speeds must be equal. If the endpoints are structured, the number of timeslots must be equal.

a VPI, a VCI, z VPI, and z VCI--You can allows CPC to auto-select the next available VPI and VCI. For CPC to auto-select the VCI enter 0. For CPC to auto-select the VPI enter -1.
Service object profile--You do not have to use a Service object profile: you can specify the values manually when you create the CBR service. For a list of the profileable attributes and the acceptable values, refer to "Profileable Attributes for a CBR Service."
Service element profile--You can specify the name of the Service element profile you want to use for the service or you can use the available defaults.

Step 7 Save the Service by clicking the save button on the toolbar.

Step 8 Apply the Transaction by clicking the apply button on the toolbar.
