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 director y number for both B-channels, or one for each 
B-channel.

SPID: The Ser vice Profile ID generally looks like the director y number with some extra digits (the TID) appended 
to it. SPIDs are used only in Nor th America. The number of SPIDs received from your ISDN ser vice provider can 
var y from none to two.

TID (Terminal ID): This usually a four-digit number associated with the SPID. 0101 is the most popular, but it 
can var y in form. You may need to add a TID to each SPID you use when you configure the Netopia R3100.

If you encounter other unfamiliar terms, check the glossar y.

Depending on the type of ISDN switch protocol you use, you may be required to enter SPIDs in the ISDN Line 
Configuration screen. Generally, SPIDs are used with Nor th American (United States and Canada) switch 
protocols.

The exact format of ISDN SPIDs is sometimes a point of confusion. This is because several formats exist, and 
some formats allow variations.

The table below displays the general SPID formats for the types of Nor th American ISDN switch protocols 
suppor ted by the Netopia R3100. The formats shown are a subset of possible SPID formats, but in most cases 
they should work. 

In the following table, xxxxxxx represents the director y number assigned to your ISDN line, and yyy represents 
your area code.
