ISDN Configuration Guide
This appendix contains supplemental ISDN configuration
information.
Definitions
The following terms are used in this appendix:
Directory number: The actual phone number associated with the
ISDN line you order. Depending on the type of switch protocol used
on your line, there may be one directory number for both
B-channels, or one for each B-channel.
SPID: The Service Profile ID generally looks like the directory
number with some extra digits (the TID) appended to it. SPIDs are
used only in North America. The number of SPIDs received from your
ISDN service provider can vary from none to two.
TID (Terminal ID): This one- or two-digit number is associated with
the SPID. It’s usually 1 or 01 for the first SPID and 2 or 02 for the
second SPID, but it can vary in form. You may need to add a TID to
each SPID you use when you configure the Netopia Router.
If you encounter other unfamiliar terms, check the glossary.
