CHAPTER 1
Introduction
Description of the RVON-8 Voice Over Network Card
Installed directly into the ADAM Intercom frame, the RVON-8 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 telephone network. The RVON-8 delivers an integrated solution for connecting custom key-
panels to the Intercom Matrix over standard IP networks by supporting 8 channels (ports) of audio IN and OUT.
The RVON-8 card supports all standard, hot-swappable and configurable features through Telex’s AZedit configuration
software as well as support for remote keypanels and virtual keypanels via VOIP (voice over IP).
RVON-8 support Telex®Intelligent Trunking over IP. Trunking is a method of using relatively few audio paths for a large
number of potential users. Because it is flexible, a trunked system can expand along with your business, to accommodate a
growing number of users. RTS’ Intelligent Trunking is a proven technology, which provides the same capabilities and ease of
use for intercoms - seamless routing and path finding of communications between facilities regardless of distance - as does the
long distance telephone system for phone calls.
RVON-8 is fully compatible with internationally recognized standards and supports the following protocols: G.711, G.729AB,
and G.723 (2 speeds).

Installation
Installation of the RVON-8 Card into the ADAM System
When inserting the RVON-8 card into the ADAM system, the following considerations need to be made:
•Gently insert the RVON-8 card into the correct slot. If the card is forced or twisted while inserting, a pin on the backplane
could short or break causing the card to become inoperable.
•When inserting the RVON-8 card into the ADAM system, make sure to insert it into a compatible backcard. If the card is
inserted into a incompatible backcard, undesirable results can occur.
NOTE: All cards are now shipped with a colored coding key in the middle of the connector. For more information, see “Color
Key Code” on page 3.
Color Key Code
On the RVON-8 card, Telex has provided a color key code and knock-outs for digits 1-8 to ensure a compatible connection
between cards. The RVON-8 card color is blue, and will only insert into a blue coded backcard.
NOTE: Only newer systems have the color coded backcards.
FIGURE 1. RVON-8 Color Key Code. This Key Code only allows the RVON-8 to plug into an RVON8 compatible
backcard.

NOTE: The RVON-8 connector is mechanically offset from the standard AIO-8 cards. DO NOT FORCE MATING THE
CARDS.
Addresses and the RVON-8 Card
Because the RVON-8 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 com-
pliant, all cards must have a unique MAC ID when shipped from the manufacturer. Typically, the MAC ID of a piece of hard-
ware, such as the RVON-8 card, has a fixed or static address. Whereas, the RVON-8 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-8
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.
Switches and Connections
IMPORTANT: You must remove the card from the frame in order to change any DIP switch settings.

9. In the RVON-8 Channel drop down list, select the channel you want to use to communicate to another device across the
network.
10. In the Device IP Addr: field, enter the IP Address of the device to which you want to connect.
11. From the Device Type drop down list, select the type of device to which the RVON-8 card is connecting.
12. From the Device Channel drop down list, select the channel on the device to which the RVON-8 card will communicate.
13. From the CODEC Type drop down list, select the CODEC type you want to use for this channel.
14. From the Packet Size drop down list, select the size of each audio packet.
NOTE: A CODEC is an algorithm used to compress audio. There are 5 Codices supported by Telex: G.711 μs law, G.711A
law, G.729AB, G.723 (5.3k), and G.723 (6.3k). The type of CODEC will 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 (see “Specifications” on
page 2). 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 Administrator 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 happen.
15. Select Enable VAD (Voice Activity Detection), if you want to conserve bandwidth when the audio level is below a given
threshold.
NOTE: Voice Activity Detection saves network bandwidth by stopping the flow of audio packets when silence is detected.
VAD is similar to VOX.
At this point you may choose another channel to configure or choose another card to configure.
16. Once you are completely finished, click Apply.
Apply sends all of the changes to all the cards in the intercom, or click Cancel to discard all changes you make.
