RVON-8 RTS™ Voice Over Network Card

3. From the RVON-8 drop down list, select the slot in which the RVON-8 card resides, if it is not already

selected.

4. In the IP address field, enter the IP address you have assigned to the RVON-8 card.

5. In the Network Mask field, enter the Network Mask of the network to which the RVON-8 card is

connected.

6. In the Default Gateway field, enter the Default Gateway address (if applicable) of the network to

which the RVON-8 card is connected.

A Default Gateway is only required if the RVON-8 connections are between LANs

Under Settings for Pass-Through Serial via Ethernet

7. In the Target IP Addr. field, enter the target IP address of the device you want to connect to over

Ethernet.

8. From the Serial Baud Rate drop down list, select the baud rate at which the data is transmitted.

Under Settings for Connected Devices

Note: You MUST configure the channel settings on each end of a connection and ensure the same codec and

packet size are selected at each end. Remember, the RVON-8 card has 8 different channels which can be

configured.

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 Codecs supported by Telex, G.711 µ 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 the table on page 8. 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. How

ever, 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 happen. Use the table on page 7 to help you determine the CODEC type and

packet size appropriate for your environment.

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.
