ISDN TIP FOR BELLSOUTH CUSTOMERS!
Despite the fact the BellSouth originated the proposal for the standardised SPID (see above)
many regional Bell South offices leave off the last two digits of the SPIDs.
If you are a BellSouth customers and are given a SPID of the format: Area Code + 7 digits +
01 and you get "SPID Error" your correct SPID is probably Area Code + 7 digits + 0101 or
Area Code + 7 digits + 0100.
In the case of Natl.I‐1 or 2, and DMS‐100 Custom. Carefully verify that you have the correct SPID
from the Telco, and that you have properly entered it into the system. It must be 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.

HOT TIP!
If you suspect the SPIDs given you are wrong, or the basic line provisioning (configuration) is
incorrect, call the Telco and ask to speak to someone who can "log into the switch". They will probably
need to have someone call you back. Only once you have this person on the line, and they are logged
into the switch, ask them to look at the SPIDs programmed there. Also get this person's fax number and
send them the ISDN ordering information from the Appendix of this manual.
Sometimes the information in the business office computer is wrong. By verifying what is programmed
into the actual switch, you can save time and frustration.
We've included some useful diagnostic aids in the system to help you determine where a
problem is originating. A good starting point is the ISDN status, accessible on the LCD by
pressing the Status button:
Status Screen for ISDN troubleshooting
This screen shows the status of the ISDN connection for each B channel. You can determine if
the line is connected and whether the line and the Xstream are successfully configured. In
addition, information about calls is displayed here. One of the following status words will be
shown for each active ISDN channel:
Available line status messages are:
Inactive – This indicates that neither the built‐in NT1, nor the S interface is active. This will be
displayed if no ISDN line is present (or is connected to the wrong jack on the Xstream). It is also
displayed on ETS 300 (Euro‐ISDN) lines after periods of inactivity (the ETS 300 standard allows
the central office switch to put the line to sleep).
SPID Pending – This option is only valid when the Telco selection of the TEL menu is set to
"Natl.I‐1" or "DMS Cust.". Indicates that the S interface is initialized and the SPID has been sent
to the Telco Switch and the Xstream is waiting for it to be accepted (it will be sent again if no
reply is received). This may be briefly displayed before the S interface has come up.
