ZEPHYR XPORT USER’S GUIDE

active line present). When using POTS you can speed boot time by pressing <5> and <6> simultaneously when the "Found ISDN card" message is displayed.

I can’t find the ISDN setup menu.

The ISDN circuit should be connected to the Xport before you power the unit up, or it will boot into POTS mode.

Why does the unit abruptly switch to phone mode without warning, even though my line is very good and my connections show good quality readings?

Be sure to disable call waiting on lines that support this feature. You can verify if this is the case by calling into the unit while it is dialed up. You should get a “busy signal” in this case. If you hear “ringing” the line supports call waiting. In most areas of the USA you can disable call waiting on outbound calls by adding *70 to the beginning of the number to be dialed. Or, you can enter these digits in the Prefix field in the Xport’s menu.

Why won’t the Xport establish a POTS (modem) connection? Why do my connections show a very low quality reading?

Check the following:

Are you using “Xport” as the “Mode” when you dial? The Xport call type indicates you wish to make a modem connection.

Does the problem happen only with long distance calls? Try using a different carrier.

Is the Xstream running version 2.5.0 or later? It must have version 2.5.0 to communicate using aacPlus.

Is the COUNTRY setting set to match the country where the Xport is located?

Is the line you are using of adequate quality? If the Xport works fine from other lines served from the same Telco central office you may have a problem with a bad line. Here are some things to check before calling the Telco:

Is the line “shared” between the Xport and any other device?

Try disconnecting all other equipment connected to the line in question. For best performance, you don’t want extra equipment or phone jacks on the line to be used with Xport.

If you must use a line that is used for other equipment, it is best to wire up an A/B switch as close as possible to where the line enters the building, and feed a dedicated wire and jack and for the Xport from the switch.

What kind of wiring is used between the network interface (or Telco protector block) and the jack? If it is the older cloth wire, or the red/green/black/yellow untwisted cable, you should replace the wire with twisted pair wire (category 3 or greater).

If there is a network interface, try plugging Xport directly into it (thereby bypassing the inside wiring and other devices).

You may have a problem with your phone line. Try using a different line to see if that makes a difference.

If the problem occurs with all lines from a given Telco central office, but not on lines from different central office suspect a network problem.
