ISDN TIP!
In an emergency, to save a remote, you can sometimes get a
line working without the proper SPIDs or line configuration by
dialing into it. This fix is only temporary and the line will fail to
initialize next time the Zephyr is booted.
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.
They'll probably need to have someone call you back. Verify
this person is logged into the switch. Get their fax number and
fax them the Zephyr's ISDN information 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.
have properly entered it into the Zephyr. It must be exactly correct in order for anything
to work! We've seen a few cases where it was given incorrectly by Telco personnel, so it
might be a good idea to re- check with them if things are pointing in this direction. For
a list of known working SPIDS by Telephone Company see the Appendix.
We've included some useful diagnostic aids in the Zephyr to help you determine where
a problem is originating. The key are the ISDN status words on the left side of the LCD
basic status screen:
•
inact/inact means no ISDN connection
•
wait/init means incorrect SPID1.
•
init/init means wrong protocol set up at CO, or Zephyr is not matched to it
•
Ready/init means only one working ISDN channel
•
Ready/wait means incorrect SPID2
•
Ready/Ready means OK on both ISDN channels
IMPORTANT!
One caveat regarding the Ready/Ready indication: If you
have this indication with the Zephyr Telco mode set to PTP
and you cannot dial, it is likely that your line is Natl ISDN 1.
(The PTP protocol does not require SPIDs, so the Zephyr does
not send or check them; it just assumes the line is OK in this
regard, so it gives the Ready indication, though the line is
waiting for the SPIDs. In this case calls would immediately fail.
