Configuring H.323

This procedure describes the configuration of the H.323 protocol which is embedded on the IP Signaling Series 3 card.

For offline configuration, you must have a node view window open in configuration mode. If you want to configure online, the LLC and SwitchManager must be running. For information on running LLC and SwitchManager refer to the SwitchKit documentation.

When you configure H.323 for the first time you need to add the H.323 IPS Series 3 (IPS S3) card to the node. Excel also recommends configuring parameters, such as IP addresses and spans before you start configuring H.323.

For information beyond the default values provided, please refer to the Converged Services Platform, Developer’s Guide: IP.

Follow the steps to configure the H.323 protocol on an IP Signaling Series 3 card.

• Select the IPS S3 card. Go to the Configuration menu and select Card®H.323 IP Signaling Series 3 Configuration.

• Select the IPS S3 card. Go to the Configuration menu and select H.323®H.323 IP Signaling Series 3 Configuration.

• Right-click the H.323 card and select H.323 IP Signaling Series 3 Configuration from the menu list.

2 In the H.323 IP Signaling Series 3 group, enter the ID (valid values: 0-63) and IP Address.

3 Enter the Polls information. Excel recommends you set the poll interval to: 2 seconds (200 in 10-ms units). The range of valid values for Poll Interval and Maximum Missed Polls is: 1-65535.

4 Enter the Link Down Timer in 10 millisecond units, if you want to change the default value of two minutes.

5 Enter the Matrix/CPU primary/shared IP address and port number. The valid values for the port number are: 1- 65535. Note: After clicking OK for this configuration, these fields are disabled for subsequent viewings of this dialog box.

6 Click Configure Attributes. This opens the Configure H.323 Attributes dialog box. The dialog box opens with default settings for the H.323 attributes configuration. The default values work for many scenarios. If you need to change any of the defaults, please follow the next steps.

8 Select Auto Gatekeeper Discovery and Registration to be able to change from the default setting No to Yes.

9 Select Auto Gatekeeper Discovery only to be able to change from the default setting No to Yes.

10 Select the Variant ID to enable the H.323 variant, which currently supports Variant ID: 0 (ITU).

11 Select Version Number to enable the H.323 version, which currently supports version 2.

12 Select Terminal Type to enable the H.323 terminal type, which currently supports GW with No MC.

13 Select Gateway Technology Prefix and type in the numeric value. The pound sign is inserted automatically at the end of the digits (maximum 8 characters).

14 Select RAS PPL Indication and click Send or Do not send. Send means the switch sends RAS PPL event indications to the host. Do not send means the switch will not send RAS PPL event indications to the host.

• Select Vendor ID/H.323 ID. Type in the Vendor ID (string, maximum 63 characters).

• Select URL and type the string in the text box, if you want to provide this (string, maximum 63 characters).

• Select E-Mail and type the string in the text box, if you want to provide this (string, maximum 63 characters).

NOTE: All the aliases are null terminated strings and the null character will automatically be inserted at the end of the string.

17 Under Additional Host Signaling Parameters, you can select Media Connection Address.

18 Under Re-register with Gatekeeper, you can select Enable Cfg Byte 2 (RAS PPL).

20 Select and enter the H.225 Timers in 10 milliseconds (integer), the H.245 Timers and RAS Timers.

22 Click

or right-click in the range column and select Add/Modify Range. The Specify Channel Range dialog box opens.

23 From the drop-down list, select the Span and Channel numbers. If you do not specify, the Start channel is defaulted to zero. If you do not specify the End channel, it is defaulted to the last channel in that specified "end" span.

25 Click Open or right-click the Range column and select Open Configuration Dialog.

27 Click OK to close the Configure H.323 Attribute dialog box and to return to the Configure H.323 IP Signaling Series 3... dialog box.

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

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.

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

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.

Boot protocol for TCP/IP

An H.323 entity on the network that provides address translation and controls access to the network for H.323 terminals and other end points. The gatekeeper may also provide other services to the endpoints such as bandwidth management and locating gateways.

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.
