SPID1
SPID2 Enter the Service Profile Identifier (SPID) numbers supplied by your ISDN service
provider. Used only in North America, SPID numbers are unique identifier numbers
provided by your local telephone company when you install an ISDN line. Usually,
two SPID numbers are provided, but sometimes one and even none is provided.
In many cases, both SPID numbers are required if you want to connect using two B
channels. A SPID number is typically 14 digits long and consists of the 10-digit
telephone number (area code plus phone number), followed by the digits “0101.”
Other variations of this number are possible and your telephone company can
provide you with the correct information for your ISDN line. The SPID numbers may
be automatically detected and entered if you select Auto Detect as the ISDN Switch
Type.
