The OnLAN 323 Product Series

The RADVision OnLAN 323 product series provides connectivity for multimedia applications between IP based networks such as LANs, Intranets and the Internet and circuit switched networks such as ISDN and PSTN. The OnLAN 323 product series consists of the L2W-323P Gateway (PRI), L2W-323 Gateway (BRI and V.35), the MCU-323 Multipoint Conference Unit, the VIU-323 Video Interface Unit and the NGK-100 Gatekeeper. These “building blocks” allow users to communicate over different networks, products and protocols.

The L2W-323 Gateway

H.320 protocols, allowing the exchange of voice, video and data between H.323 based conferencing endpoints on IP networks and H.320-compliant endpoints on circuit switched ISDN networks as well as Voice over IP (VoIP). Connecting to an ISDN PRI, BRI or V.35 interface, the L2W-323 Gateway provides connections at rates of 384 Kbps, 128 Kbps or 64 Kbps. In conjunction with the internal Gatekeeper, the L2W-323 and L2W-323P Gateways operate as multimedia PBXs allowing internetwork calls, direct inward dialing and call transfer.

The MCU-323 Multipoint Conference Unit

only or full multimedia multipoint conferences at rates ranging from 64 Kbps to 1.5 Mbps. The MCU-323 also provides audio mixing (G.711 A/µ Law), video switching (H.261 CIF/QCIF, voice activated) and simple monitoring of conferences using a web browser.

The VIU-323 Video Interface Unit

Overview

An Introduction to H.323

H.323 is the globally accepted standard for audio/video/data communications over IP-based networks. It specifically describes how multimedia communications occur between user terminals, network equipment, and assorted services on Local and Wide Area Internet Protocol (IP) networks.

What is the H.323 Standard

H.323 is an umbrella recommendation from the International Telecommunications Union (ITU) that specifies real-time multimedia communications over Internet Protocol-compliant networks. It defines new models of interaction for both point-to-point and multipoint conferences. For example, H.323 specifies how gatekeepers can provide address translation and bandwidth management and how gateways can connect terminals on the LAN to those on the WAN.

H.323 Network Components

The H.323 specification defines a number of new network components that interoperate with other standards-compliant endpoints and networks by virtue of an H.323/H.32X gateway.

Following are the network components defined by the H.323 standard:

Terminals

communications. Most H.323 terminals are desktop computers running H.323 compliant software. All terminals must support voice communications while video and data are optional. However, if these other media are supported, H.323 specifies what modes of operation are required so that all terminals supporting video and/or data can work seamlessly together.

Gateways

conferencing endpoints on the IP network and other ITU-compliant terminals (for example, H.320 room systems) on other circuit switched networks.

Gatekeepers

providing network administrators the ability to incorporate management and security policies into the network. Although the H.323 recommendation describes the gatekeeper as an optional component of a functional H.323 system in practice the gatekeeper is essential. The H.323 gatekeeper is responsible for providing address translation between LAN aliases and IP addresses, call control and routing, basic telephony services such as directory services and PBX functions, H.323 traffic bandwidth usage control and total network usage control and the implementation of overall system management and security policies.

Multipoint Controller Units (MCUs)

an optional multipoint processor or processors (MP). The MC is the conference controller. The MC handles negotiation between all terminals to determine common capabilities and controls conference resources such as multicasting. The MC does not deal directly with any of the media streams. This is left to the MP, which does the mixing, switching, and other processing of audio, video, and/or data bits.

Terminals, gateways and MCUs are also known as H.323 endpoints. The collection of all terminals, gateways, and MCUs managed by a single gatekeeper comprise an H.323 Zone.

Between H.323 and H.320

H.320 is the ITU standard for video conferencing over digital lines like ISDN. The standard describes recommendations for both multipoint and point-to-point video conferencing over circuit-switched networks (CSNs).

If you want your H.323 LAN endpoints to communicate with H.320 terminals within a LAN segment, you need a VIU-323 to convert the H.320 to H.323 protocol.

If you want your H.323 LAN endpoints to communicate with H.320 terminals on circuit- switched networks without actually connecting each LAN endpoint to an ISDN line, you need a gateway that converts between these protocols.

as well as instructions for setting up the configuration terminal with the OnLAN Configure 323 configuration software.

procedures for the VIU-323. Once these are complete, you can make calls through your VIU-323.

If you are installing and configuring the VIU-323 for the first time, read Chapter 4, “Preparing for Configuration” before configuring.

3-8

Preparing for Configuration

This chapter describes several pre-configuration considerations and procedures. It covers the following topics:

Planning the Configuration

Setting Up the Configuration PC

Installing the Configuration Software

Planning the Configuration

Before you start configuring the VIU-323, plan the procedure to ensure a smooth and effortless configuration procedure. This section reviews the items to consider.

Prerequisites

IP Address

The VIU-323 operates on an IP-based LAN. Each VIU-323 must have a unique IP address. The VIU-323 leaves the factory with a default IP address, which you must change to the unique IP address according to your network IP addressing scheme (contact your network administrator). For configuration via a terminal session see “Defining IP Addresses via a Terminal Session” in Chapter 9. For configuration via the LAN, see "Selecting the VIU-323 for Configuration" in Chapter 5.

IP Subnet Mask

To ensure proper configuration, the VIU-323 and the configuration PC must be on the same LAN and have the same subnet mask defined.

Default Password

The VIU-323 configuration is protected by a modifiable configuration password. The default password for all VIU-323s is VIUrv.

Note: The password can be up to 16 characters and is case-sensitive: for example,“VIU”

must be typed in uppercase; “rv” must be typed in lowercase.

We recommend that you change this password and assign a unique password for each VIU-323 during configuration. For information, see “Modifying the Password” in Chapter 5, “Basic Configuration.”

Default Gatekeeper IP Address

The VIU-323 must be registered with an H.323 gatekeeper (either a RADVision Gatekeeper or another company’s). The configuration program will ask you to enter the default Gatekeeper IP address.

4-1

Preparing for Configuration

Default Router IP Address

Enter this field if the LAN to which the VIU-323 is connected connects through a router to another LAN or the Internet.

VIU-323 Phone Number

Use this number to dial in to the VIU-323 from other H.323 or H.320 devices (16 digits maximum).

Checklist of Prerequisites

Before you start configuration, obtain the following information (from your network administrator, for example); enter the values below to make VIU-323 configuration more convenient:

❒ VIU-323 IP address: __ __ __ . __ __ __ . __ __ __ . __ __ __

❒ VIU-323 IP subnet mask: __ __ __ . __ __ __ . __ __ __ . __ __ __

❒ Configuration PC IP subnet mask: __ __ __ . __ __ __ . __ __ __ . __ __ __

❒ Default gatekeeper IP address: __ __ __ . __ __ __ . __ __ __ . __ __ __

❒ Default router IP address: __ __ __ . __ __ __ . __ __ __ . __ __ __

❒ VIU-323 phone number: ___________________________

❒ Incoming default bandwidth: ______

❒ Outgoing default bandwidth: ______

❒ Default VIU-323 configuration password: VIUrv (case sensitive)

Note: We recommend that the VIU-323’s subnet mask be the same as the configuration

PC’s subnet mask so that the VIU-323 configuration program will display the VIU-323’s IP address for your selection in the first configuration screen; otherwise, you must manually enter the VIU-323’s IP address.

4-2

Configuration PC Requirements

The configuration PC must:

Have Windows 95/98/NT installed.

Have network software that is Winsock 1.1 compatible installed (for example, Microsoft TCP/IP Stack for Windows 95/98/NT).

Reside on the same LAN segment as the VIU-323 you want to configure.

Have an IP subnet mask that matches the IP subnet mask of the VIU-323 you want to configure.

The OnLAN Configure 323 system configuration software, installed.

Installing the Configuration Software

The VIU-323 setup procedure installs the configuration program OnLAN Configure 323 on your hard drive.

To install OnLAN Configure 323

1. Start Windows.

2. Insert the VIU–323 CD ROM in your CD drive

3. The RADVision OnLAN Tools Setup window displays. If it does not display automatically, access the CD ROM using Windows Explorer and invoke the Setup.exe file.

4. Follow the onscreen instructions for installation.

Upgrading the Configuration Software

Upgraded versions of VIU-323 software may also require that you upgrade the OnLAN Configure 323 software configuration program (check the release notes that accompany the software).

To upgrade OnLAN Configure 323, follow the steps in “Installing the Configuration Software,” above. Note that if you install the new version of OnLAN Configure 323 to the same directory of the previously installed version, you will overwrite the original; to keep the previous version, install the new version in a different directory.

4-3

Preparing for Configuration

Navigating the Configuration Software Screens

The configuration software comprises sequential screens that can be accessed through the Next and Prev buttons. Some screens also have secondary screens that are accessed through buttons. These are identified by the name of the screen they invoke, for example, the Date/Time Settings screen is a secondary screen of the Unit Identification screen and can be accessed from the Date/Time button on this screen. The following is a description of the configuration software navigation buttons.

5-14

Making Calls with the VIU-323

This chapter describes how to make calls using the VIU-323. It covers the following topics:

Setting up a Call

Basic Dialing

Changing Outgoing Bandwidth

Changing Incoming Bandwidth

Changing Both Incoming and Outgoing Bandwidth

Setting up a Call

After the room system is connected to the VIU-323, the VIU-323 is connected to the LAN, and both the room system and the VIU-323 are up and running. Use the room system dialer to make your call.

Note: The VIU-323 does not support single-channel (1B) calls.

Bandwidth

In all cases, the bandwidth of the calling room system (via the VIU-323) must be the same as the bandwidth of the receiving endpoint (gateway, VIU-323, H.323 terminal, or H.320 terminal). This means that before you call:

You must know your VIU-323’s bandwidth and that of the unit you are calling.

If you are calling through a gateway, you must know the gateway’s service number and the type of connection (e.g., ISDN BRI) between the gateway and the unit you are calling.

If you are calling through an IMUX, you must know the IMUX profile.

In a basic call, the default bandwidths of both the calling and the receiving units are the same. However, there are cases when you must change the default bandwidths of the calling VIU-323 or the receiving VIU-323, or both. You can do this by adding a dialing prefix (to change the outgoing bandwidth) or a dialing suffix (to change the receiving VIU-323’s incoming bandwidth).

Note: We recommend that you define all VIU-323s on the same LAN segment with the same

bandwidth. For optimal quality, if all the participating terminals support it, use 768 Kbps.

6-1

Making Calls with the VIU-323

Basic Dialing

When the bandwidth of the calling VIU-323 is the same as that of the receiving unit, dial the extension or phone number of the unit you’re calling.

Dialing Examples

Dialing Within a LAN

When the calling VIU-323s and the receiving endpoint are on the same LAN segment and set to the same default bandwidths, simply dial the extension of the endpoint you’re calling.

Example

5555

Where 5555 is the extension of the endpoint you are calling.

Two-Channel (2B) Dialing Through a Gateway

When you are dialing through a gateway to an H.320 unit, you must take into account not only the bandwidths of the calling VIU-323 and the receiving unit, but the bandwidth of the circuit switched network that connects the two sides.

If:

You are making a BRI call, and

The default bandwidth of the calling VIU-323 is 2x64 Kbps, and

The default bandwidth of the receiving unit is also 2x64,

then you don’t have to change the bandwidth. You must, however, dial:

The gateway’s service prefix, followed by

The first channel phone number, followed by

The 2nd number delimiter.

If the second channel phone number is different from the first, you dial the digits of that number that differ from the first number after the 2nd number delimiter (see example below). If it’s the same as the first, don’t dial it.

6-2

Basic Dialing

Example

80 7654321*

Where 80 is the gateway service prefix, 7654321 is the phone number for both the first and second channels of the unit you are calling, and * is the 2nd number delimiter. (You don’t have to dial the phone number twice because the phone numbers are the same for both channels.)

Example

80 7654321*7654322

Where 80 is the gateway service prefix, 7654321 is the phone number of the first channel of the unit you are calling, * is the 2nd number delimiter, and 7654322 is the phone number of the second channel.

or dial: 80 7654321*2

Where the delimiter * is followed by the digits of the second number that differ from the first number dialed, in this case the number 2.

Note: Since it is not common that the default outgoing bandwidth of a VIU-323 is 2x64

Kbps, you will probably have to change the outgoing bandwidth.

Dialing Through a Gateway and IMUX

When you are dialing through a gateway and an IMUX to a unit that has the same bandwidth as the calling VIU-323, dial:

The gateway’s service prefix, followed by

The IMUX profile, followed by

The phone number of the receiving unit; if this is a 2x64 Kbps call, this will be

The first channel phone number, followed by

The 2nd number delimiter.

If the second channel phone number is different from the first, you dial the digits of that number that differ from the first number after the 2nd number delimiter. If it’s the same as the first, don’t dial it.

6-3

Making Calls with the VIU-323

Example

80 #001 7654321*

Where 80 is the gateway service prefix, #001 is the IMUX profile, 7654321 is the phone number for both the first and second channels of the unit you are calling and * is the 2nd number delimiter. (You don’t have to dial the phone number twice because the phone numbers are the same for both channels.)

Dialing Through Two Gateways to a Remote LAN Endpoint

When you are dialing through a second gateway to an H.323 endpoint on a remote LAN, if:

You are making a BRI call, and

The default bandwidth of the calling VIU-323 is 2x64 Kbps, and

The default bandwidth of the receiving unit is also 2x64,

then you don’t have to change the bandwidth. You must, however, dial:

The gateway’s service prefix, followed by

The remote gateway’s phone number; then

When you are prompted by an IVR message (for example), dial the extension of the remote endpoint followed by a hash mark

Example

80 7654321 (IVR prompt) 6666 #

Where 80 is the gateway service prefix, 7654321 is the phone number of the second gateway, and 6666 is the extension of the remote unit.

Note: Since it is not common that the default outgoing bandwidth of a VIU-323 is 2x64

Kbps, you will probably have to change the outgoing bandwidth. Similarly, it is also uncommon that the bandwidth of an H.323 device is 2x64 Kbps, so you will probably have to change the incoming bandwidth.

Changing Outgoing Bandwidth

When you make a call, it is transmitted from the calling VIU-323 at the default outgoing bandwidth, which is set during VIU-323 configuration; however, if the endpoint you are calling is set to a different bandwidth, or if you must go through a gateway which requires a different bandwidth, you can change the default bandwidth of the calling VIU-323 by adding a prefix to the dialing stream.

6-4

Changing Outgoing Bandwidth

Why Change the Default Outgoing Bandwidth?

To make a call, the bandwidth of the calling VIU-323 must match that of the called endpoint. When default settings do not match, you can force a change in the bandwidth of the calling VIU-323.

There are three instances when this is necessary:

When the bandwidth of the receiving unit differs from the bandwidth of the calling VIU-323.

When the bandwidths of the two units are the same, but to get through the gateway, the bandwidth must be changed.

When you are calling another VIU-323 and high bandwidth is not available—during peak calling hours, for example.

Note: When dialing from one VIU-323 to another, you can change the incoming bandwidth

of the VIU-323 that is receiving your call by adding a dialing suffix

How to Change the Bandwidth

Add the prefix before the dialing stream to force a change in the bandwidth of the VIU-323 that is calling.

The following table displays the prefixes that you dial to force a change in the outgoing bandwidth (note the difference between prefixes for non-restricted and restricted bandwidths):

To Force Calling

Bandwidth to:

2 x 64 Kbps (2B) #00

128 Kbps #10

256 Kbps #20

384 Kbps #30

Making Calls with the VIU-323

Dialing Examples

Note: The default outgoing and incoming bandwidths are the same and are referred to

below as “default bandwidth.”

Dialing within a LAN

When the calling VIU-323 is set to 384 Kbps and the receiving unit is set to 128 Kbps, dial:

The dialing prefix, followed by

The endpoint’s phone number.

Example

#10 3333

Where #10 is the prefix that forces the calling VIU-323’s bandwidth to 128 Kbps and 3333 is the extension of the receiving endpoint.

Dialing from a VIU-323 on a LAN through a Gateway (BRI) to an H.320 terminal

When the calling VIU-323 is set to 384 Kbps but the call is sent at 2x64 Kbps through the gateway to the remote H.320 terminal, dial:

The dialing prefix, followed by

The gateway service prefix, followed by

The first channel phone number, followed by

The 2nd number delimiter;

Example

#00 80 7654321*

Where #00 is the dialing prefix, 80 is the gateway service prefix, 7654321 is the phone number for both the first and second channels of the unit you are calling, and * is the 2nd number delimiter. (You don’t have to dial the phone number twice because the phone numbers are the same for both channels.)

6-6

Changing Incoming Bandwidth

Example

#00 80 7654321*7654322

Where #00 is the dialing prefix, 80 is the gateway service prefix, 7654321 is the phone number of the first channel of the unit you are calling, * is the 2nd number delimiter, and

7654322 is the phone number of the second channel. or dial: #00 80 7654321*2

Where the delimiter * is followed by the digits of the second number that differ from the first number dialed, in this case the number 2.

Dialing Through a Gateway and IMUX

When you are calling through a gateway and an IMUX to a unit that has a different bandwidth, dial:

The dialing prefix, followed by

The gateway’s service prefix, followed by

The IMUX profile, followed by

The phone number of the receiving unit; if this is a 2x64 Kbps call, this will be

The first channel phone number, followed by

The 2nd number delimiter.

Example

The calling VIU-323 is set to 384 Kbps but the receiving unit is set at 128 Kbps; dial:

#10 80 #001 7654321

Where #10 is the prefix that sets the bandwidth to 128 Kbps, 80 is the gateway service prefix, #001 is the IMUX profile, and 7654321 is the phone number of the remote unit.

Changing Incoming Bandwidth

When making calls between two VIU-323s, you can force the VIU-323 receiving the call to change its default bandwidth to match the bandwidth of the VIU-323 making the call.

To do this, add a dialing suffix after the phone number of the remote VIU-323. Dialing suffixes are for non-restricted bandwidths only and are described in the following table:

6-7

Making Calls with the VIU-323

To Force Receiving

Bandwidth to:

2 x 64 Kbps (2B) 00

2 x 56 Kbps (2B) 01

128 Kbps 10

112 Kbps 11

224 Kbps 21

256 Kbps 20

336 Kbps 31

384 Kbps 30

672 Kbps 71

768 Kbps 70

Use Suffix:

Note: A dialing suffix can be used only when calling to a VIU-323 from another H.323

endpoint. This includes calling from an H.320 unit through a Gateway.

During VIU-323 configuration, you enter the VIU-323’s phone number in the Network Parameters screen. This phone number is registered with the gatekeeper (whose IP address

is entered in the same screen). The VIU-323’s phone number is registered in the gatekeeper with up to 11 aliases (configurable); 10 of these are the original number with a suffix added, for example, if the phone number is 5555, the gatekeeper adds the suffixes 00, 01, 10, 11, 21, 20, 31, 30, 70 and 71 so that:

6-8

Dialing 5555 tells the receiving VIU-323 to operate at the default bandwidth.

Dialing 5555 00 forces the receiving VIU-323 to operate at 2x64 Kbps.

Dialing 5555 01 forces the receiving VIU-323 to operate at 2x56 Kbps.

Dialing 5555 10 forces the receiving VIU-323 to operate at 128 Kbps.

Dialing 5555 11 forces the receiving VIU-323 to operate at 112 Kbps.

Dialing 5555 20 forces the receiving VIU-323 to operate at 256 Kbps.

Dialing 5555 21 forces the receiving VIU-323 to operate at 224 Kbps.

Dialing 5555 30 forces the receiving VIU-323 to operate at 384 Kbps.

Dialing 5555 31 forces the receiving VIU-323 to operate at 336 Kbps.

Dialing 5555 70 forces the receiving VIU-323 to operate at 768 Kbps.

Dialing 5555 71 forces the receiving VIU-323 to operate at 672 Kbps.

Changing Incoming Bandwidth

Why Change the Default Incoming Bandwidth of the Remote VIU-323?

For a call to succeed, the bandwidth of the called VIU-323 must match that of the calling unit, but this does not always happen. When the bandwidth settings do not match, you can force a change in the bandwidth of the receiving VIU-323. There are three instances when this is necessary:

When the bandwidth of the VIU-323 being called differs from the bandwidth of the unit that is calling.

When you don’t know the bandwidth of the VIU-323 being called.

When you are calling another VIU-323 and high bandwidth is not available—during peak calling hours, for example. (In this case you may want to add a prefix as well as a suffix.)

How to Change the Default Bandwidth

Add the suffix after the dialing stream or when prompted, for example, by the Gateway’s IVR (Interactive Voice Response).

Dialing Examples

Note: The default outgoing and incoming bandwidths are the same and are referred to

below as “default bandwidth.”

Dialing within a LAN

When an H.323 endpoint calls a VIU-323, within a LAN and the receiving VIU-323 is set to a different bandwidth, dial:

The extension of the receiving VIU-323, followed by

The appropriate dialing suffix.

Example

The calling endpoint is set to 384 Kbps but the receiving VIU-323 is set at 128 Kbps; dial:

7777 30

where 7777 is the receiving VIU-323’s extension and 30 is the suffix that changes the incoming bandwidth of the receiving VIU-323 to 384 Kbps.

6-9

Making Calls with the VIU-323

Making a BRI call through Two Gateways to a Remote LAN Endpoint

If the bandwidth of the calling VIU-323 is 2x64 Kbps and the receiving VIU-323’s bandwidth is 384 Kbps, dial:

The first gateway’s service number, followed by

The phone number of the remote gateway;

When you are prompted by an IVR message (for example), dial:

The extension of the remote VIU-323, followed by

The dialing suffix.

Example

80 7654321 (IVR prompt) 4444 00

Where 80 is the service prefix of the first gateway, 7654321 is the phone number of the remote gateway, 4444 is the extension of the remote VIU-323, and 00 changes the receiving VIU-323’s bandwidth to 2x64 Kbps.

Changing Both Incoming and Outgoing Bandwidth

In some cases, you must dial both a prefix and a suffix. Because the network sets bandwidth availability at any particular time, you may have to use lower bandwidths during peak hours. You may therefore have to use a prefix to force the outgoing call to a lower bandwidth and a suffix so that the VIU-323 you are calling can receive the call. Remember that you can only use a suffix when calling from one VIU-323 to another.

Example

If both VIU-323’s are set to 384 Kbps, but the call doesn’t go through, send the call at 128 Kbps by dialing the following:

#10 80 7654321 (IVR prompt) 4444 10

Where #10 changes the calling VIU-323’s bandwidth to 128 Kbps, 80 is the service prefix of the first gateway, 7654321 is the phone number of the remote gateway, 4444 is the extension of the remote VIU-323 and 10 changes the receiving VIU-323’s bandwidth to 128 Kbps.

Note: The dialing suffix (when used) must match the dialing prefix (when used); for

example, when the prefix is #20, the suffix, if necessary, must be 20; when the prefix is #00, the suffix, if necessary, must be 00.

Upgrading the VIU-323

This chapter describes how to upload a new version of the VIU-323.

Upgrading the VIU-323 Software

Upgrades for VIU-323 are issued periodically. The Software Upload utility is required to upload new versions of VIU-323 software. The procedure for upgrading software is:

! Install the Software Upload utility on the configuration PC.

! Use the utility to upload the new version of VIU-323 software (the “flash file”).

Installing the Software Upload Utility on the Configuration PC

You need to install the utility only when a new version of VIU-323 software is released (newly-purchased VIU-323s contain the latest software version, so the Software Upload utility is not required). With a single installation of the utility, you can upgrade all your VIU-323s.

To install the Software Upload utility on the configuration PC

1. From the configuration PC, start Windows.

2. Insert the VIU–323 CD ROM in your CD drive.

3. The RADVision OnLAN Tools Setup window displays. If it does not display automatically, access the CD ROM using Windows Explorer and invoke the Setup.exe file.

4. Follow the on–screen instructions for installation.

Setup creates a directory on the configuration PC (C:\Rvcfg\Rvburn is the default path) and copies the utility software to the directory. In addition, Setup adds:

! The menu item, Software Upload Utility in the Program menu item, RADVision

Tools (for Windows 95/98/NT).

Tips and Troubleshooting

This chapter covers problems you may encounter when configuring the VIU-323 and suggests actions you can take to solve these problems. It covers the following topics:

LED Indications

Common Problems

Analyzing Problems

IP Address Problems

LED Indications

The Power LED does not light

This indicates that the VIU-323 is not properly connected to the power source. Make sure the power cable is firmly connected to the VIU-323 and to the power outlet.

The Link LED of a connected LAN port does not light

This indicates that the LAN port is not connected to the network segment. Make sure that the connections are secure, you are using the correct Ethernet cable and connector, and the devices at both ends of the Link are powered-up. For the LAN connector pin-out, see Appendix A, “Cable Connectors and Pin-outs.”

Common Problems

One end can call the other but not vice versa.

Indicates that there is a probable configuration problem at one end. Check each configuration for the proper phone number, IP address, subnet mask and default router address.

Gatekeeper configuration problem.

Check the registration list on the gatekeeper and make sure that each endpoint is registered there.

Make sure that the additional phone numbers created by the VIU-323 do not conflict with other numbers assigned.

Unable to establish a call. The VIU-323 reports the line is busy and the green Session LED on the front panel of the VIU-323 is lit.

The VIU-323 did not drop the session properly after the previous call. Restart the VIU-323.

9-1

Tips and Troubleshooting

The VIU-323 indicates it is unable to call.

Check the gatekeeper endpoints list and make sure that each endpoint is registered; then check the VIU-323 registration at both ends.

Check the network connection by pinging the far end VIU-323; if the ping fails, there is a network problem; if the ping succeeds, turn off the room systems at both ends and turn them back on; if this still does not work turn off the VIU-323s at both ends and turn them back on.

Poor audio quality or last syllable repeats continuously. Video has “artifacts” (areas where the screen does not update properly). Call drops during videoconferencing.

These problems usually indicate a poor network connection. Try making the call at a lower speed, if possible, or try making the call during off-peak hours.

If the above suggestions solve this problem, there is a network problem that you should check.

Cannot place a call through a gateway.

Check the dialing stream to make sure the gateway prefix is correct.

Check that both ends of the call are set at the same bandwidth; if required, adjust the bandwidth using the correct prefix.

Note: Firewalls will generally prevent calls from going through. Make sure that you are

not trying to send a call through a firewall.

Analyzing Problems

If the problem persists after trying the above solutions, apply the following procedures:

Network Quick Check

Use the Ping command to assess the network connection.

1. Working from a PC or UNIX system that is on the same segment as one of the failing VIU-323, ping the IP address of the far-end VIU-323. The ping command indicates if there is network connectivity and provides the round-trip delay time. Run the ping command a few times or let it run continuously for a minute to see if connectivity is consistent. Also note the round-trip delay variation.

9-2

Analyzing Problems

2. Run the Ping command, using the gatekeeper’s IP address as the destination.

If connectivity seems good and round trip delays are consistent, go to the next topic.

If connectivity is absent (the ping fails) or if connectivity regularly fails during a short run, the network is at fault. Similarly, if the round-trip delay jumps around substantially (more than a factor of 3), a network problem is likely.

Sending a Ping Command from a PC to a VIU-323

You send a Ping command from a Windows PC to a VIU-323 to see if the VIU-323 is properly connected to the LAN.

To send a Ping command

1. On the Windows PC, from the Start menu, select Run (alternatively, select Programs/Command Prompt or Programs/MS-DOS prompt).

2. In the window that opens, type Ping followed by a space and the IP address of the VIU-323 you want to check (for example, Ping 123.30.80.48).

If a series of “Reply from…” messages appears on the screen, the VIU-323 is connected. In this case, type Exit and press Enter to close the window.

If timeout messages appear on the screen, the VIU-323 is not connected. In this case:

a. Check the physical connection of the LAN cable between the VIU-323 and

the LAN hub (and the PC’s connection to the LAN hub).

b. Check the VIU-323’s IP address.

c. Send another ping. If the second ping is also unsuccessful, you must redefine

the VIU-323’s IP address .

d. Type Exit and press Enter to close the window.

9-3

Tips and Troubleshooting

Verify Component Interactions

Try a direct VIU-323-to-VIU-323 call to see if the problem lies with the gatekeeper.

1. Set up two VIU-323s to connect directly to each other rather than through the gatekeeper.

2. Configure the VIU-323s to point to each other:

a. Run OnLAN Config 323 on a PC and specify the IP address of one of the

VIU-323s.

b. Advance to the Network Parameters dialog box and change the Default Gatekeeper

ID to the address of the destination VIU-323.

c. Save and transfer this configuration.

3. Make the same change on the destination VIU-323, specifying the source VIU-323’s IP address as the default gatekeeper.

4. Try the call again.

If the configuration works, the room system and VIU-323s are in order; the problem is with the gatekeeper, which is either broken or configured incorrectly.

If the call still fails, check the default router IP address on both VIU-323s and make sure they are correct. If this does not fix the problem, go to the next topic.

Eliminate the Network

Try a VIU-323-to-VIU-323 call with both VIU-323s on the same LAN segment to see if the problem is within the equipment itself (if this is not possible—for example, if the equipment is remotely located—skip to the next topic):

1. Set up the VIU-323s to connect directly to each other rather than through the gatekeeper. This may involve moving one system onto the local segment. Modify the IP address of the moved VIU-323 to a value appropriate for the local segment.

2. Configure the VIU-323s to point to each other:

a. Run OnLAN Config 323 on a PC and specify the IP address of one of the

VIU-323s.

b. Advance to the Network Parameters dialog box and change the Default Gatekeeper

ID to the address of the destination VIU-323.

c. Save and transfer this configuration.

3. Try the call again.

If this configuration works, the network is at fault.

If the problem still exists, it is likely that one piece of equipment has failed. Selectively replace pieces of equipment and run test calls until you locate the broken component.

9-4

Analyzing Problems

Network Problems

If problems disappear on the local segment but return as soon as you involve the larger network, the problem may lie in the network itself. There are several tests you can run to troubleshoot problems between remote sites, even if you are unable to test local videoconferences.

Verify the Problem is with the Network

1. Reduce the speed of the videoconference to the lowest level possible (64K or 128K). If the videoconference runs well at this lower speed but has problems at higher speed, the network is suspect.

2. Try the videoconference at different times of day. Because network use varies over a 24-hour period, videoconferences may work better at some times of day than others. If you find a videoconference works well during “off” hours, such as early morning, but fails at busy times (typically late morning or mid-afternoon), the network is suspect.

3. Try a network route that has fewer router hops, such as across a leased line or an alternate ISP. To determine the number of router hopes, run a traceroute (“tracer Ipaddr” on a PC, “tr Ipaddr” on a UNIX system). If the videoconference behaves better on a connection with fewer routers, the network is at fault.

Tips and Troubleshooting

IP Address Problems

If you experience difficulty setting the VIU-323 IP address parameters (IP address, default router IP address and IP subnet mask) using the OnLAN Config 323 system configuration software, an alternate method is to connect the configuration PC to the VIU-323 console (serial) port and run a terminal session. After the terminal session, run OnLAN Config 323 to define the other VIU-323 parameters.

Defining IP Addresses via a Terminal Session

To establish a terminal session between a PC and the VIU-323

Note: The VIU-323 and configuration PC do not have to be disconnected from the LAN.

1. Make sure the VIU-323 is turned off.

2. Connect the 9-pin male connector of the null modem cable to the console (serial) port on the front panel of the VIU-323 and connect the cable’s nine-pin female connector to the configuration PC’s COM 1 port (alternately, you can connect the cable’s 25-pin male connector to the PC’s COM 2 port, but this may require a female/female adapter).

3. Use Windows HyperTerminal™ or a similar application to open a console session. Set the following parameters for Windows HyperTerminal:

Port Settings:

Rate=9600

Data bits=8

Parity=none

Stop bits=1

Flow control=none

Properties:

Function, arrow, and Ctrl keys act as=Terminal keys

Emulation=ANSI

Backscroll buffer lines=500

Terminal Setup:

Underline=enabled

Blink=enabled

ASCII Setup:

Wrap lines that exceed terminal width=enabled

Note: All other values are default values.

4. Turn on the VIU-323 to start a terminal session. The message: “Press any key to start configuration…” appears (if no message appears, press CTRL+X and wait for the message). Press any key within six seconds of receiving the message to display a menu of configuration options.

5. Type 1 and press Enter; type 1 again and press Enter.

6. Enter the IP address for Interface No. 1 and press Enter (the address must be entered in dotted decimal format without leading zeroes, for example: 170.4.10.20).

7. Enter the default router IP address and press Enter (the address must be entered in dotted decimal format without leading zeroes, for example: 170.4.10.20).

8. Enter the IP subnet mask in hexadecimal notation and press Enter. The PC displays configuration information and the VIU-323 automatically reboots.

9. When Ready appears on the PC, disconnect the cable that connects it to the VIU-323 and close the terminal session.

After you set the IP addresses, run OnLAN Config 323. Note that the Select Unit screen will display the IP address of the VIU-323 that you defined above in the list of RADVision units. Select it from the list and continue to configure the VIU-323. Notice that the IP addresses defined above appear in their appropriate screens during the configuration procedure.
