Configuring VDAC-ONE

This procedure describes online configuration of the VDAC-ONE (Voice-Data Access Concentrator) card.

The VDAC-ONE card performs two-way conversion between circuit-switched data and packet-switched Ethernet data. The IP Signaling Series 3 card enables the CSP to communicate with H.323 entities in the network architecture. For information beyond the default values provided, please refer to the Converged Services Platform, Developer’s Guide: Internet Protocol.

1 From the node view, invoke the VDAC-ONE configuration dialog box by doing one of the following:

• Select the VDAC-ONE card in the node view. Go to the Configuration menu and select Card®VDAC Configuration.

• Right-click on the VDAC-ONE card in the node view and select VDAC Configuration from the menu.

2 Enter the IP Address and Subnet Mask of the main board. After these values are entered and you tab to the Gateway field, most of the other fields and module configuration become enabled.

Important! If you do not want internal routing tables to be created for this card, you must use the Configure PPL Tool dialog box to uncheck this option. See Specifying PPL Files. The internal routing tables that are enabled by default create your IP-to-span-channel mapping that is installed on the CSP. Also, a separate config file is added to the SwitchManager file which is also shown in the Configure PPL Tool dialog box in Specifying PPL Files.

4 To assign all logical span IDs for the VDAC-ONE card, specify the Starting Span Number.

Important! The CSA provides default routing by mapping the specified spans with the IP Addresses of the VDAC-ONE modules.

5 Specify the IP addresses for each Module in the Configure Module group. When you click out of the module IP address cell, the Start Span:Channel and End Span:Channel get populated automatically from having specified the Starting Span Number in the Channel Configuration group box.

6 If you are using IP-based routing, enter the Routing IP Address and Routing Mask of the endpoint that is within or outside the main board network.

• Selected Advanced IP Routing in the H.323 IP Signaling Series 3 card resource attributes configuration dialog box.

7 Select the module you want to configure and click Configure Module. The Configure Resource Attributes VDAC-ONE:... dialog box opens for the selected module.

The dialog box opens with default values. You can change the values, if required. The valid range of values for the fields, 2833 Dynamic Payload Type and 2198 Dynamic Payload Type, is 0-127 except for 102, 103, and 105.

11 To invoke the Channel Group Configuration dialog box, do one of the following:

• Right-click the blue area around the card slots and select Channel Group Configuration from the menu.

• Go to the Configuration menu and select Node Configuration®Channel Group Configuration.

The Channel Group Configuration dialog box opens. If you are configuring the Channel Group for your VDAC-ONE card for the first time, the table cells are empty. See the next screen shot.

The VDAC-ONE configuration shown in the next screen shot includes example values.

12 Double-click the table cell in the Range column, the Specify Span Range dialog box opens as shown below:

15 In the Channel Group Configuration dialog box, click Open to invoke the Configure VDAC Channels dialog box. The dialog box opens with default values. Note that the Interworking group box refers to routing.

Excel recommends configuring Answer Supervision Mode with Propagate Answer and Notify Host selected as shown in the next example screen shot:

16 Specify your settings by marking check boxes and selecting from the drop-down lists.

18 In the Configure Channel Groups dialog box, fill in a name for your channel group.

Configuration changes are not sent to the CSP until you select the menu: Configuration® Configure Through SwitchMgr® Send Only Modified Configuration To Switch.

Internet Protocol. Part of the TCP/IP family of protocols used to route messages and tracks the addresses of nodes.

Session-Initiation Protocol. A signaling protocol used for establishing sessions in an IP network. A session could be a simple, two-way telephone call, or it could be a collaborative multi-media conference session.

ITU-T standard defines a set of call control, channel setup, and codec specifications for transmitting real-time voice and video over networks that do not offer guaranteed service or quality of service.

The protocol used in most local area PC networks. Typically, most Ethernet networks support data transmission speeds up to 10 Mbps, but 100 Mbps is also possible.

An Internet Protocol enhanced service node that supports the deployment of voice and data services in circuit, packet, and converged networks. The Converged Services Platform (CSP) features an open and multi-functional platform design that enables developers to quickly create and deliver new revenue-generating services for both legacy and next-generation networks.

A 32-bit address, used in IP routing, which includes a Network address identifier assigned by a central authority and a Host ID (an end station identifier assigned by a LAN administrator).

The bits of an Internet Protocol (IP) address used for a subnetwork.

A device that translates calls between an IP network and another network, typically the PSTN.

See Programmable Protocol Language.

The point in the Excel platform where a DS0 connects to a network. Also known as a "socket."

Range of channels provided by T1 or E1 transmission service. A physical span is a group of channels taking up a single physical wire. A logical span is a group of channels taking up less than a single logical wire, or carried over more than one physical wire.

See Converged Services Administrator.

Interworking is a software feature within the Excel platform call control layer that enables protocol conversion by analyzing and converting Network Signaling (NS) Layer 3 information.

A computer, attached to the Excel platform through an RS-232 or Ethernet link, from which you run the telecommunications application that controls the Excel platform.
