ZEPHYR XPORT USER’S GUIDE

Anything better possible with mobile phones?

Not yet. Current generation phones have a maximum data rate of 14.4 kbps, not enough for anything approaching high fidelity.

We expect to interface digitally to next- generation phones with fast rate capability. This will be via the Ethernet or Interface connectors, depending on what the phone makers bring us. Japan’s I- Mode system, based on 3G Qualcomm technology, has a 64 kbps ISDN- like channel option today. If that catches on around the world, you will be ready to use your Xport for remotes with quality equal to landline ISDN codecs. Since the fixed end of I- Mode is via ISDN, your studio side Xstream will be ready. (This mode will not be possible with POTS codecs that don’t use ISDN at the studio side because there would be no way to get the 64 kbps down an analog line.)

Why do you include a multi-band digital AGC and limiter? Maybe that is a little over-the-top?

Because they are under the same roof, the Telos and Omnia designers often share ideas and work together. Omnia has been making a streaming audio dynamics processor for some time, which was designed in partnership with the Telos codec guys to sound good with coded audio. So it really was natural to get some of this Omnia work back into Telos products – hence the integration into Xport. The bitrate is very low, and we want every practical tool to smooth and clarify the audio. That is why we went “whole hog” with a multi- band DSP approach – it really makes a difference to the quality. We figure most of the time you are using a POTS codec, you want some control over dynamics anyway. (Think sports announcers.) Of course, you can switch it off if you prefer a more purist approach.

Where can I get answers to my technical questions?
