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 North 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 
North American ISDN switch protocols supported by the Netopia 
Router. The formats shown are a subset of possible SPID formats, 
but in most cases they should work. 

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

Note: AT&T 5ESS custom point-to-point switches have no SPIDs 
and are not represented in the table above. However, this type of 
switch configuration is supported by the Netopia Router.
