A note from the CEO

It's been nearly 10 years since Telos brought you the original Zephyr – the first product
in the world to use MP3, and the first to bring all the necessary pieces for ISDN remotes
together in one easy- to-use and reliable package. In 2001, we offered you the latest
MPEG technology and numerous improvements with the introduction of the Zephyr
Xstream family of codecs. Together, these have become among the most successful and
enabling tools in broadcasting’s digital era.

Unless you enjoy reading user manuals for the thrill, you presumably have the new
Zephyr

XPORT

at hand, and you will be using it with an ordinary telephone line to
connect to a Zephyr Xstream ISDN codec. Prepare to hear the highest fidelity low- bitrate
coding method on Earth, aacPlus, in action. For the first time, you will experience FM­like audio over analog telephone lines – with surprisingly detailed highs and fuzz- free
clarity, on both speech and music. You will also experience remarkable stability. Because
the studio side is connected digitally, modem performance is considerably more reliable
than with POTS- only schemes.

Maybe you are thinking, "What took you so long?" Those with long memories may recall
that we had a POTS codec prototype using MP3 at the NAB radio show many years ago,
before any others were marketed. However interesting the demo, we decided MP3 and
the other codecs around at that time were just not up to our snuff on quality over
modems.

All the while since, we’ve been keeping our eyes and ears open. We knew POTS Telco, we
knew codecs, and we knew ISDN, so we knew what we were looking for. Now, finally, all
the pieces have come together to let us give you all the right stuff.

My guiding principle at Telos is to make the stuff I would have wanted for myself when I
was in the CE game. So, here’s another one I sure could have used! It’s really cool when
something like this one comes together so well.

So, go ahead and use this baby to shock and amaze. We are looking forward to hearing of
your experiences using the Xport…

To extract maximum reliability from real-world analog Telco lines,
based modem that lets us optimize for maximum performance with audio signals. Normal
modems are designed for non- real- time data, where a bad packet may be re-transmitted
without much consequence and “retraining” is not a major problem. With audio, this would
result in serious drop- outs. A modem for live audio requires a different set of trade- offs that are
not possible with off- the-shelf consumer modem chips.

Your studio Zephyr Xstream becomes a universal codec, connecting with both Xport and ISDN
codecs. This saves you money, rack space, operator training, telephone lines, and console/router

This section will get you up and running quickly. We will use a microphone and
headphones. We will place a call to the Telos test line so you can verify correct operation
of the unit.

h HOT TIP! The Xport is intended to be used in conjunction with a Telos Zephyr

Xstream back at the studio. An Xport cannot call another Xport, nor can it communicate
with POTS codecs that use proprietary coding methods.

The Xport can also be used to call any Telephone or hybrid, however in that case the
results will be standard telephone quality audio.

how you feel. You don’t want to sit around and read a manual. You want to plug- in your

• A dynamic Microphone, together with a cable ending with a 3- pin XLR "male"

Success, Step-by-Step:

Connecting the Audio Inputs/Outputs

You want to hear something, don’t you? Connections are needed for sending audio to
the remote location and receiving audio. You will need to provide a microphone and
headphones, along with an appropriate cable.

Headphones

Connect your headphones to the headphone jack

on the rear panel.

Microphone

Connect your dynamic microphone to the MIC. INPUT jack on the rear panel using
an appropriate cable (normally an XLR male to XRL female).

Be sure the line you connect to your Xport really is an analog line. In many offices, and
some hotels, you will find perfectly ordinary-looking phones that are connected to in­house phone systems using special, proprietary lines. DO NOT connect your Xport to such
lines. See Section 3 for more information.

2.2 Placing Your First Call, to Telos

Located less than a mile from the Rock ‘n’ Roll Hall of Fame, there is always something
interesting playing on the Telos test line. Let’s call Cleveland. If you prefer, you can call
our test line in Europe. That number is listed under “Test Lines” on page iii at the front
of this manual.

Follow these step-by-step instructions:

1. Remove your headphones.

2. Press the <DIAL> button once. Use the keypad to enter the Telos test line number.

Be certain to precede it with any number you may need to dial to access an outside

line (such as "9") and/or to place a long distance (such as "1") or international call.

The number is [phone]. Press the <DIAL> button again.

h HOT TIP! If your phone line has the feature "call waiting," you should temporarily

disable this by entering "*70" (or other special code) before the number to be dialed.

3. You should see a series of messages that say Modem Off Hook, Dialing Finished,

Modem Detected, Connecting., Connecting, Connecting…, Connected, and finally,

Connect Lock 0:00:01 .

If successful, the words "Connect Lock"

will appear along with a call duration

timer.

You should now see audio on the Receive

audio meter (labeled "Rcv") moving as the

audio is received from the test line.

Put on your headphones and listen. You may adjust the relative volume of your local

microphone audio and the audio from Telos by adjusting the MIX control on the

Xport's front panel.

4. Whether or not you have successfully connected, press the <DROP> button twice.

You want to be sure to disconnect, as this may be an expensive call.

5. If you have successfully connected, go on to the next section. If you have not, try

again. If you do not succeed, here are a few things to try:

• Wait an hour and try again. The Telos test line may be busy.

• If you need to dial a prefix (such as 9) try entering a pause after this digit and

before the rest of the number it by pressing <#> twice (a "," will be displayed)
when dialing.

• USA users should try calling using a different long- distance carrier. To do so,

insert the carrier’s seven- digit access code. The number to dial starts with any

prefix needed for you to get an outside line, followed by the long distance

access code, followed by the Telos test line number. See section 5 for additional

codes. Let us say you don’t need a prefix to dial out (and most people don’t)

and you want to use MCI. Dial:

1010222 1 216- 781- 9310

If this works, you should contact your local telephone company to determine

who your default long distance carrier is.

• Review the information in Section 5 (What if to do if…).

• Call Telos Customer Support for assistance. The Xport may provide error

messages under some circumstances. Have these messages ready when you

call, as they will help speed the process of solving your problem (see page iii).

Now you are ready to call the world. Remember your promise to read the entire manual!
