Checking LAN communications

If you are experiencing delays and interruptions in transferring data across the LAN, take these steps:

• Place the IR system on a separate LAN segment, if necessary.

IR systems that move speech traffic across the LAN by using Proxy Text-to-Speech, VOIP, or VoiceXML should be on a separate LAN segment. A separate LAN segment may also be required if there is heavy traffic between voice response applications and remote databases.

• Check current LAN connections and capacity.

You can check LAN traffic with a number of free sniffers that are available online. Work with your LAN administrator as needed to assess connections and make required changes. The following recommendations apply to LAN bandwidth requirements:

• If the IR system transfers speech data over the LAN, the bandwidth required for speech operations should be less than 70% of total bandwidth.
• If the IR system does not transfer speech data over the LAN, the band width required for speech operations should be less than 20% of total bandwidth.
