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.

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.
