APPENDIX 11-9
List of Known Working SPIDs by Telephone Company
Your SPIDs may be different! The phone company can assign any darned thing they
want to as a SPID... but they usually adhere to these standards.
Note, for each line there is only one configuration which will work. Your SPID is dis-
tinct from your telephone number and does not necessarily contain your area code or
telephone number (although this is generally the case).
A standardized SPID format for national ISDN of XXXYYYZZZZ0101 has been phased in
and is worth trying.
Incorrect SPIDS will be indicated by a line status of “Wait, Init” on ZephyrExpress.
Often the Telco will leave the last “00” or “01” off the end of your SPID when giving it to
you.
For the latest info, check http://www.zephyr.com. Additional SPIDS can be found at
INTEL’s SPID Page (http://support.intel.com/enduser_reseller/isdn/spid-tip.htm).
