ZEPHYR XPORT USER’S GUIDE

h HOT TIP!

The Xport uses the center pins of the 6- position miniature modular (RJ- 11 style) jack. In parts of Europe, we have seen the same type of jack using different pins.

In order to get the best performance from your Xport on POTS lines, be sure to set the COUNTRY menu selection for the correct setting. If your country is not listed, try the settings for USA and for CTR21. See section 2.3.1

POTS EXT. JACK

This jack allows you to connect a telephone to your Xport. This telephone is for use when you are not using the Xport. To avoid accidentally causing interference while the Xport is in use, this jack is inactive whenever the Xport is "off hook". We suggest you pack a good quality phone as part of your remote kit. It is useful for troubleshooting, among other things.

When you are using ISDN, this jack does nothing.

3.1.2 ISDN INTERFACE (Optional)

The ISDN interface may not be present in your Xport. You can check if it is available by pressing <NAV> twice from the default menu and checking to see if ISDN Setup is available as a menu choice. See Section 6 (Technical Information) for how to install the ISDN option. See Section 3.5 (Xport's ISDN interface) for information on the ISDN configuration menu and ISDN status screen.

hHOT TIP! If you intend to use ISDN, connect the ISDN line before powering on the Xport. The ISDN interface will only be active if the unit is connected to ISDN at the time of startup.

U INTERFACE (only active if option 1701-00056 is present)

This interface will only be active if you have the specified version of the ISDN interface. It allows interfacing directly to 2- wire 2B1Q ISDN circuits, as used in the USA & Canada, directly. This is a 6- position/4- pin miniature modular jack (RJ- 11 style) and uses the center pins to connect to the ISDN circuit. This connection requires a standard telephone cable with 6- position/2- pin or 6- position/4- pin miniature modular plugs (RJ- 11 style) on both ends.

U Interface Sync LED (active only if option 1701-00056 is present)

A green LED, located beside the U interface jack, shows the status of the built- in NT1. Normal status is indicated by the LED being lit. If off there is no ISDN present at the U connector. Rapid flashing (about eight times per second) indicates an ISDN line is connected and is being initialized. If the NT1 can contact the central office (or an active repeater), the LED will blink slowly (about once per second) as the S connection between the NT1 and the rest of the ISDN interface occurs. The LED will come on solidly when all handshaking is completed and the basic line connection is good. If this LED does not light continuously, once you have connected your 2- wire "U" ISDN circuit, you may wish to skip ahead to Section 5
