5 What to do if…

Sadly, the world is not perfect. We all know this, but that knowledge does not help us when unexpected problems happen right before the "big broadcast". This section should help when things won't work.

When dialing using POTS the status goes to “off hook” and then immediately back to “on hook”. What should I do?

Check the following:

Is this really an analog phone line? If it was connected to a phone with more than two lines, or had a fancy LCD display it was probably a proprietary office phone. Or the line may be dead. Plug in an analog phone into the jack to see if you get dial tone.

You may have a bad phone cord. Try another cord.

Try the Xport on another line.

What does it mean when a dialogue box comes up that says “Degrading Performance! Do you want to

drop back to Phone mode?”

The means that modem performance has deteriorated. Normally you should choose “Ignore”. If the dialogue appears often (more than once every hour or two) you should choose “retrain” when convenient (NOTE retrain will cause a drop in audio for about 6 seconds). If you have tried retraining and you see this dialogue appear again, you should re-dial as soon as convenient. In the meanwhile, particularly if you are getting audible dropouts, you can select phone “Phone” (this will give greatly reduced quality, but this will allow you to stay connected without dropouts until you can redial).

What does it mean when I dial and a dialogue box comes up and says “Bit rate too low…Falling Back to

Phone Mode”???

This means the modem is unable to negotiate an acceptable connection and therefore the connection has been established in “Phone” mode. You may wish to try redialing.

What does it mean when I am connected and a dialogue box comes up and says “Lost Modem Sync…Falling back to Phone Mode” or “ Unacceptable Modem Performance…Falling back to Phone Mode”?

The modem connection has failed and therefore the connection has been converted to “Phone” mode. You should redial when convenient.

While the Xport’s custom DSP modem is designed to be as stable as possible, there are certain line conditions that can interrupt any modem. Minor interruptions will display the “Marginal Quality” dialogue (see above). In cases where the modem connection is in eminent danger of termination the system will prevent an interruption by automatically switching to phone mode and one of the above messages will be displayed. You should redial when convenient.

How can I tell if my Xport has the ISDN option?

ISDN units will display “found ISDN card looking for line…” shortly after power up. You can also go to the “About” screen to check this.

Why does my ISDN Xport take so long to boot up?

We know that menu options for things like “SPIDS” or “DNs” can be intimidating to non-technical users. Therefore, we display the ISDN setup menu only if the ISDN interface is present and active (i.e. with an
