Introduction

General Description of the RVON-1 Voice Over Network Card

Installed directly into KP-32 or KP-812 keypanels, the RVON-1 provides voice over IP (Internet Protocol) communications, for the RTS™ ADAM Intercom family. In general, voice over IP means sending voice information in digital form using discrete packets rather than the traditional hardwire connection. The RVON-1 delivers an integrated solution for connecting keypanels to the Intercom matrix over standard IP networks.

The RVON-1 is compatible with any RTS™ Matrix Intercom System equipped with a suitable RVON interface. In conjunction with any new or existing KP-32 or KP-812 keypanel, the RVON-1 brings a new level of enterprise-wide and remote access functionality to your RTS™ Matrix Intercom.

The RVON-1 card is configurable through the keypanel service menu and Telex’s AZedit configuration software. It is also fully compatible with internationally recognized standards and supports the following protocols: G.711, G.729 AB, and G.723 (2 bit rates).

The RVON-1 reaffirms RTS’ history of providing support for the latest technology in a fully supported backward compatible manner to all its RTS™ products.

Features

Installation The RVON-1 provides a single RJ-45 Ethernet connection for use with a 10 BAS-T or 100 BASE-TX

network.

1 Channel of AudioIN and OUT

The RVON-1 card supports one channel IN and OUT and has configurable network and bandwidth parameters that can be tailored to individual network functions.

Ethernet Compatible The RVON-1 card uses standard Ethernet protocols and is compatible with 10 BASE-T and 100 BASE-

CHAPTER 2

Installation

Installation of the RVON-1 Card

Before using the RVON-1 card with the KP-32, a few modifications need to be made to the keypanel. If the serial number on your KP-32 keypanel is 61170, you will need to update you backpanel with the Ethernet RJ-45 connection (part number 9080-7656-002) knockout present. Also, the KP-32 flash chips need to be replaced with larger flash chips (4MB) see Table 2, “Flash Chip replacement part numbers.,” on page 4.

To install the RVON-1 card, do the following:

1. Remove the cover from the KP-32 keypanel.

2. If present, remove the GPI/O board.

The GPI/O board contains the general purpose input and output connections located on the back cover.

3. Using a chip extractor, carefully remove and replace the flash chips located at U2 and U3 on the KP-32 Motherboard, see

“Flash Chip Replacement” on page 4.

4. Using a hammer and screwdriver, remove the specified knockout pieces, see Figure 2..

5. Mount the supplied spacer on the RVON-1 card on the corner of the card near the DIP switch. See Figure 3 on page 6.

6. Securely connect the RVON-1 card to the KP-32 motherboard , see page X for connector specifics.

Figure 2. Knock out positions for the RVON-1 card on the KP-32

Installation

7. Replace the GPI/O board.

8. Re-attach the backplate to the KP-32 keypanel. Be sure to secure the spacer with a screw in the back plate. See Figure 2 on

page 5

9. Replace the cover on the KP-32 keypanel.

In the KP-32 keypanel, the RVON-1 card connects to the KP-32 by way of the J2 connector on the RVON-1, attached to J4 on the KP-32 header.

10. Gently secure the board in place (see Figure 4.).

In the KP-812, the RVON-1 card connects to the KP-812 by way of the J2 connector on the RVON, attached to J37 on the KP812 header.

Addresses and the RVON-1

11. Gently secure the board in place

NOTE: Be sure the orientation of the board is correct, otherwise undesirable effects may occur. Make sure the RJ-45 connection is positioned so it will fit through the specified knockout on the back cover. When installing the RVON-1 card in an existing KP-32 or KP-812, each keypanel needs to be upgraded to include the following:

KP-32

•A backplate that allows for the RJ-45 connection (Ethernet).

•Larger flash chips.

KP-812

•A backplate that allows for the RJ-45 connection (Ethernet)

•Extension for the RJ-45 connector.

RVON-1 Relay

When connected to an Ethernet LAN, audio comes from the RVON-1 card; and, when Ethernet is not plugged in, the audio comes from the AIO connection. Note, the user does not need to remove the RVON-1 to switch to AIO mode.

WARNING: You cannot have both an Ethernet connection and an AIO connection simultaneously. If the Ethernet and AIO are connected simultaneously, no audio communication will occur.

Addresses and the RVON-1

Because the RVON-1 has an Ethernet interface, it is required to have a MAC (Media Access Control) Address. This is a low level address that contains 48 bits. Do NOT confuse this address with an IP (Internet Protocol) Address. In order to be IP compliant, all cards must have a unique MAC ID when shipped from the manufacturer. Typically, the MAC ID of a piece of hardware, such as the RVON-1 card, has a fixed or static address. Where as the RVON-1 card’s IP Address can change over time.

The MAC Address uniquely identifies each node of a network and interfaces directly with the network media. The RVON-1 card has a small 8-pin serial device on the board that the processor can read the unique MAC Address from. For more information on MAC IDs, contact technical support.

NOTE: Each RVON-1 card needs to be programmed with its own IP Address.

Figure 5. The J37 connector on the KP-812 board.

Installation

Configure the RVON-1 from the KP-32

To use the RVON-1 with the KP-32, the KP-32 firmware must be at version 2.0.0 or higher. In turn, the firmware requires that larger flash chips be used as well (see See “Flash Chip replacement part numbers.” on page 4.).

8. From the Packet Sized drop down list, select the size of each audio packet.

NOTE: A CODEC is an algorithm used to compress audio. Codecs dictate the quality of audio you hear and the network bandwidth used. The packet size determines how much audio data is carried across the network in each transmitted packet. The CODEC type and packet size chosen require different amounts of bandwidth from the network. As with the CODEC type, the packet size you choose for the audio transfer will affect the audio you hear and the bandwidth you use over the network. The larger the audio packet you choose to use, the lower the bandwidth used. However, the larger packet size can result in a higher delay and longer gaps if the packet is lost. On the other hand, smaller packet sizes result in larger bandwidth use, but lower delays and smaller gaps if the packet is lost. The Intercom System Engineer and the Network Designer may want to work together in choosing the CODEC type and packet size suitable for the size of the network, so degradation of network resources does not occur.

9. Select Enable VAD (Voice Activation Detection), if you want to conserve bandwidth when the audio level is below a

given threshold.

NOTE: VAD saves network bandwidth by stopping the flow of audio packets when silence is detected. VAD is similar to VOX.

10. Once you are completely finished, click Apply.

CHAPTER 3

Configuration

Download RVON-1 Firmware Through AZedit

NOTE: AZedit sends firmware directly to the RVON-1 card over Ethernet. This is different from other I/O cards (except the RVON-8) that receive the firmware from the Master Controller. For this reason, verify the PC running AZedit is able to contact the RVON-1 card via the network, or is configured with a Gateway IP Address that can contact the RVON card. If it is not, AZedit will not be able to find the RVON-8 card. To test the connection, pin the RVON card from a command line. For more information on how to test for a connection, see Appendix A.

To download the RVON-1 Firmware, do the following:

1. Open AZedit.

2. From the Status menu, select Software Versions and then Keypanels.

The Keypanel Version screen appears.

3. On the Keypanel Version screen, select the Show RVON-1 Versions check box.

4. Select and right click the keypanel which has the RVON-1 installed, and then select Download RVON-1.

The Download Device Firmware screen appears.

Configuration

5. Using the Browse feature, browse to the file to be downloaded.

6. Click Open.

The Download Device Firmware screen appears.

7. Click Begin Download.

The download begins.

8. Click OK.

The RVON-1 firmware download is complete. This takes a minute or two to occur.

WA R NI N G !: Do NOT power down the keypanel until you have verified the new version information from AZedit. If the card loses power while reprogramming the onboard flash memory, the card may become unbootable and may need to have its flash chips reprogrammed at the factory.

9. Verify the correct version is shown on the Keypanel Version screen.

NOTE: You can also download the RVON-1 firmware through Status > Port s. You will not be able to check the version once the download is completed from the Port Status screen.

CHAPTER 4

Basic Network Configuration

This section covers basic network configuration set-up and testing. Also covered are basic concepts and operations, including the difference between LAN and WAN networks and how IP Addressing is used.

In a networked environment, such as a company, typically there are many computers connected together using a router or a switch. In larger companies, there may be several different routers distributed in buildings and plant locations. A router allows any LAN-side computer to communicate with other computers and devices outside the LAN (local area network). Routers send data packets from one place to another place on a network. routers use network addresses to route packets to the correct destination. For example, in a TCP/IP network, the IP (internet protocol) address of the network interface is used to direct router destinations.

Because routers help computers inside the LAN “talk” with computers outside of the LAN, the security of a company’s LAN may be compromised by gaps of open ports in the router. Security measures may have been instituted to compensate for these vulnerabilities. Consult you network administrator to learn about the security measures taken to protect your network. VPN, or virtual private network, is one such security measure to protect the intelligence of the LAN. A computer outside the LAN must have an address or key known by the VPN to allow access to the LAN. Many companies use a VPN to connect two different LANs, thus allowing the transfer of data between two networks.

LAN (local area network) vs. WAN (wide area network)

LOCAL AREA NETWORK

Simply put, a LAN is a computer network that connects a relatively small area (a single building or group of buildings). Most LANs connect workstations and computers to each other. Each computer (also known as a “node”), has its own processing unit and executes its own programs; however, it can also access data and devices anywhere on the LAN. This means many users can access and share the same information and devices. A good example of a LAN device is a network printer. Most companies cannot afford the budgetary or hardware expense of providing printers for each of its users; therefore, one printer (or device) is placed on the LAN where every user can access the same printer.

The LAN uses IP Addresses to route data to different destinations on the network. An IP Address is a 32-bit numeric address consisting of four numbers separated by periods (for example, 1.160.10.240).

NOTE: For more information on IP Addresses, see you local network administrator.

Basic Network Configuration

WIDE AREA NETWORK

A wide area network (WAN) connects two or more LANs and can span a relatively large geographical area. For example, Telex Headquarters in Burnsville, MN is connected to several branch offices in Nebraska and Arkansas over a WAN. The largest WAN in existence is the Internet.

Figure 6. Local Area Network Diagram

Figure 7. Wide Area Network Diagram

Basic Network Configuration

ACCESSING THE WIDE AREA NETWORK (WAN)

Figure 3 shows LAN IP Addresses using a common IP Address, 10.2.100.X (192.168.X.X is another common address). Most devices are shipped with these addresses as its default. It is recommended to use these addresses for LANs.

NETWORK ADDRESS TRANSLATION (NAT)

Using the initial IP Address, then converting it to a valid WAN IP Address is how the network address translation works, in theory. Once the IP address is changed, it is up to the network interface device (such as a router, gateway, switch, etc.) to keep track of which computers are talking on which ports. For example, if two local devices (PC1 and PC2 in Figure 3) both wanted to talk via port 1031, then the network interface device would have to change one of the port requests to the next available port,

1032.

PORTS

In general, a network port is an endpoint to a logical connection. The port number identifies what type of port it is. For example, port 80 is used for HTTP traffic. When you type an address into the address bar of a web browser, your computer goes to find an IP Address for the url you are requesting (http://www.telex.com). To obtain this address, the computer contacts a DNS server (Domain Name Server). Once the IP Address is found, it tries to connect to the http port of the network device (port 80). See Table 1 for a list of the more well-known port numbers.

Each network device can be set-up to respond or not respond to the various ports. The function of responding or “hosting a service” is called “serving”.

If a second workstation on the LAN wants to communicate to the same server, and happens to use the same source port number, then the LAN Modem will translate the source port number as well as the source IP address. In Table, 2, a second LAN computer wants to access a web page. The NAT device now uses port 1032 for this connection where it used port 1031 in Table 1.

Basic Network Configuration

Amazingly, all the address translation that occurs takes place automatically in order to make web browsing and other functions easier. This is also a way for large web hosting services to speed up the network by having different devices perform different functions.

IP ADDRESSES

If you do not know your IP Address, you can open a DOS screen in a Windows®- based environment and bring up the ipconfig screen.

TABLE 3 . Well-Known TCP Port Numbers

Port Number Description

Basic Network Configuration

To find your IP Address using ipconfig, do the following:

1. From the Start Menu, open a Command Prompt screen.

2. At the prompt, type ipconfig, then press Enter.

The IP configurations appear for your machine, such as the DNS suffix, IP Address, Subnet Mask, and Default Gateway.

3. At the prompt, type Exit to close the screen.

NOTE: If you want more detailed parameters for your machine, type ipconfig/All. This screen shows the computers network

configuration settings.

Ping a Computer

Pinging a computer on the network makes sure it is able to be “seen” and receive messages on the network.

NOTE: You can also ping your RVON-8 card to verify that it is responding over the network by putting the cards IP Address in place of the computer IP Address.

To Ping a computer on the network, do the following:

1. From the Start menu, select Run... .

Basic Network Configuration

2. At the Run command, type CMD to open a Command Prompt screen.

3. At the prompt, type the IP Address of the computer you wish to ping (for example, 10.2.100.130).

4. Press Enter.

NOTE: If the computer you are pinging is not responding to the ping, you will receive a time-out message in the command prompt screen.

POSSIBLE PITFALL WITH ROUTERS, GATEWAYS, AND SWITCHES

Anytime computers communicate through routers, gateways, and switches, they may be allowed or denied the connection. Network interface devices can be configured to block specific outgoing requests, as well as incoming requests, based on the IP Address and/or port. This is one of the security mechanisms of a router. This also happens when broadcast messages are sent and received.

To view the path an IP Address takes to retrieve information, you can execute a tracert from the Command Prompt Screen.

1. From the Start Menu, open a Command Prompt screen.

RVON Configuration

2. At the prompt, type tracert and type the url or IP Address you want to trace.

3. Press Enter.

The details of the tracer route are displayed.

NOTE: You will the message “request timed out” if the IP Address/ port IN or OUT is denied to the incoming or outgoing message.

4. When you are finished, type exit to close the Command Prompt screen.

RVON Configuration

RVON cards use ports for communication of audio and control packets. Because routers can be configured to block certain incoming and outgoing requests, you will need to open the following ports in your network to allow WAN connections to and from a Network Interface Device. See Table X for the ports that need to be opened for the RVON cards to operate properly.

TABLE 4. Ports necessary for RVON card functionality.

Basic Network Configuration

Below, is an example of a router configuration screen. Not all routers are configured the same way and may not look exactly like this screen.

NOTE: Linksys™ supports up to 253 nodes on a router. This is why it is called a Router/Switch because there are WAN functions like a router as well as having a 4-port LAN switch. It also does not support simultaneous forward and DHCP.

Network Terminology

Bridges

A bridge is a device that connects two LANs, or two segments of the same LAN that use the same protocol.

Sometimes called “transparent bridges, they work at the OSI model Layer 2. Simply put, they are not concerned with protocols. Their main job is to pass data to a destination address that is predetermined in the data packet.

With a bridge, all of your computers are on the same network subnet (see Subnet). This means your computers can communicate with each other and have their own Internet connection. If you assign your own IP Addresses be sure to use the same first 3 “octets” of the IP Address (for example, 192.168.0.X).

Domain Name Server (DNS)

A DNS Server is an Internet service that translates domain names (for example, in the URL http:// www.telex.com, the domain name is the telex.com) into IP Addresses. The Internet is based on IP Addresses which are numeric and since domain names are alphabetic, they are easier to remember. Every time a domain name is used it must go through the DNS server to be translated into an IP Address.

Network Terminology

Gateway

A gateway is a node on a network that serves as an entrance to another network. The gateway routes traffic

from a computer to an outside network that is serving the web pages. For example, the gateway for a home computer is the ISP provider that connects the user to the Internet.

In a corporate environment, the gateway often acts as a proxy server and a firewall. Gateways are similar to routers and switches in that they forward data to the destination and provide the path for which the data will travel to the destination.

Hub

A hub is a common connection point for devices in a network. A hub has multiple ports. When a data packet

arrives at a hub, it is copied and distributed to all of its ports so that all nodes on the LAN can see the packets.

There are three types of hubs:

passive hub

- this hub serves as a conduit for the data, enabling it to go from one device to another.

intelligent hub (also known as manageable hubs) - this hub includes addition features that enable administrators

to monitor traffic through the hub.

switching hub - this hub reads the destination address of each packet and then forwards the data pack to the

appropriate port.

IP Address (Internet Protocol Address)

An IP Address is an identifier or numerical name for a computer or device on a network. Data between computers are routed over the network using these addresses to identify the computer the message is being sent to and the computer the message is being sent from.

The format of an IP Address is a 32-bit numeric address written as four numbers separated by periods. For example, an IP Address looks like 10.100.1.1.

IMPORTANT: When working within an isolated network (meaning there is no Internet access), IP Addresses can be assigned at random just as long as they are unique to each computer and device. When the isolated network is connected to the Internet, registered Internet Addresses must be obtained. This is to prevent duplication of addresses.

The four numbers in and IP Address are used in different was to identify a particular network and host on that network. There are three classes of Internet Addresses.

CLASS A - supports 16 million hosts on each of 127 networks. CLASS B - supports 65,000 hosts on each of 16,000 networks. CLASS C - supports 254 hosts on each of 2 million networks.

LAN

A LAN is a computer network that connects a relatively small area (a single building or group of buildings). Most LANs connect work stations and computers to each other. Each computer (also known as a “node”), has its own processing unit and executes its own processing unit and executes its own programs; however it can also access data and devices anywhere on the LAN. This means that many users can access and share the same information and devices. A good example of a LAN device is a network printer. Most companies cannot afford the budgetary or hardware expense of providing printers for each of its users; therefore, one printer (i.e., device) is placed on the LAN where every user can access the same printer.

The LAN uses IP Addresses to route data to different destinations on the network. An IP Address is a 32-bit numeric address written as four numbers separated by periods (for example 1.160.10.240).

Basic Network Configuration

Port

A port, when referring to TCP and UDP networks, is an endpoint in a logical connection. The port number identifies the type of port it is. For example, port 80 is used for HTTP traffic.

Routers

A router is a device that forwards data packets over networks. Most commonly, a router is connected to at least two networks (normally LANs or WANs). Routers are located at gateways, the place where two networks are connected. Routers do little data filtering, they mainly deliver the data.

Subnet

A subnet is a portion of a network that shares a common address component. On a TCP/IP network, a subnet is described as all computers or devices whose IP Address have the same prefix.

Subnetting a network is useful because it provides security for the network as well as increases performance of the network. IP networks are divided using subnet masks.

Switches

A switch is a device that filters and forwards data packets between networks. Switches operate at the data layer, and sometimes at the network layer.

WA N

A wide area network connects two or more LANs and can span a relatively large geographical area. For example, Telex Headquarters in Burnsville, MN is connected to several of its branch offices in Nebraska and Arkansas over the wide area network. The largest WAN is the Internet.

Telnet & Serial Port Programming

RVON Serial and Telnet Commands

RVON card programming can be done via direct serial or telnet connection. There are several physical connections to an RVON board:

• Direct serial through custom debug cable (J20 6-pin bottom front)

The customer debug cable always functions as the general-purpose debug tool.

• Backcard DB-9 J2

The backcard DB-(must be disabled/enabled via a DIP Switch because it can also be used for serial port pass-through. The backcard DB-9 can be used for a debug terminal when DIP switch 6 is switched to the ON position.

• Backcard RJ-45 J1 (Telnet Only)

Setup

Serial Port 38,4000 baud, No-flow control Telnet IP Address, port 23
