HOT TIP!

If you suspect the SPIDs given you are wrong, or the basic line provisioning (configuration) is incorrect, call the Telco and ask them to verify the SPIDS and provisioning from the switch.

TheyÕll probably need to have someone call you back. Verify this person is logged into the switch. Get their fax number and fax them ZephyrExpressÕ ISDN infor- mation from the Appendix of this manual.

Sometimes the information in the Business Office computer is wrong. By verifying what is programmed into the switch itself you can save time.

ISDN TIP!

In an emergency, to save a remote, you can sometimes get a line working with- out the proper SPIDs or line configuration by dialing into it. This fix is only tem- porary and the line will fail to initialize next time ZephyrExpress is booted.

Can you place a “pots” call?

From the dialing screen, change the Mode from Zephyr to Phone and try placing a call. Try it on both outgoing lines. If you can place ordinary analog calls but not data calls, then the phone company probably didn’t give you CSD (Circuit switched data) capability. The line won’t work for data, and won’t carry high-quality audio calls.

The faxable order form in the appendix specifies CSD. Make them give it to you: it’s the reason you specified ISDN.

Is your long-distance carrier OK?

If you can successfully call locally, but long-distance calls don’t go through, ZephyrEx- press usually displays Far end disconnect, No route available, or Incompatible Bear Cap as the ISDN “Cause” phrase.

You may try another by dialing the appropriate 10XXX prefix.

Some carriers and codes that we’ve tried are:

MCI

10222

AT&T

10288

Sprint

10333

You must dial the full number, including the 1 or 011 + country code following the pre- fix. You may program the 10xxx prefix into the ISDN: Outside Line Prefix field, but you must remove the prefix before attempting local calls.

In our experience, other carriers are unlikely to be able to handle ISDN data calls. Let us know if you find otherwise.
