2.2. ISDN BRI Line
Before running the ISDN adapter, you need to get an ISDN BRI (Basic Rate Inter- face) line from your local telephone company. Sometimes, your ISP may, upon your request, order an ISDN BRI line for you when you apply for an ISDN Inter- net access account. You should get the subscriber information from your ISDN telephone company, who may inform you about your ISDN central switch type and SPID (Service Profile Identifier) number (applicable in the United States).
2.2.1 SPID (Service Profile ID)
The Service Profile ID (SPID) is applicable in the U.S. only. SPIDs are a series of numbers that informs the central office switch which services and features to pro- vide to an ISDN device. The generic SPID format comprises of 14 digits. The first 10 digits are the main telephone number on the terminal. The last 4 digits are dependent on the number of terminals on the interface and the services they sup- port.
