Information required from the ISDN BRI provider
For BRI models or units with Net/BRI modules installed, your ISDN BRI provider must
provide you with the following information:
•
The telephone number assigned to your ISDN BRI line.
•
The SPIDs assigned to your ISDN BRI line (for lines running in any mode other than
AT&T Point-to-Point). In countries outside the United States, SPIDs might or might not
be required. Check with your carrier.
•
Which channels are nailed up or unused, if any.
Generic SPIDs for NI-1 and NI-2 Service
A generic SPID format for National ISDN-1 (NI-1) and National ISDN-2 (NI-2) service is
used by some telephone companies. The format for generic SPIDs is the same for all switches,
as follows:
aaannnnnnnsstt
•
aaa
is the 3-digit area code and
nnnnnnn
is the 7-digit telephone number for the ISDN
BRI line.
•
ss
is the Sharing Terminal Identifier (ID), which is a 2-digit number from 01 to 32. These
two digits are normally 01.
•
tt
is a 2-digit code Terminal ID (TID), which is a 2-digit number from 01 to 08. These
two digits are normally 01.
For example, if the ISDN provider assigns the telephone numbers 510-769-6001 and
510-769-6002 to the ISDN BRI line, and the IDs and TIDs for both SPIDs are all 01, the
SPIDs are 51076960010101 and 51076960020101.
SPIDs for an AT&T 5ESS switch
For National ISDN-1 (NI-1) service from an AT&T 5ESS switch, SPIDs are normally in the
following format:
01
nnnnnnn
0
tt
•
nnnnnnn
is a 7-digit telephone number (not including the area code) of the ISDN BRI
line.
•
tt
is a 2-digit Terminal ID code (TID) from 00 to 62. If you have a choice, use 00 for this
code.
For example, if the ISDN provider assigns the telephone numbers 769-6001 and 769-6002 to
the ISDN BRI line, and 00 is the TID for both numbers, the SPIDs are 017696001000 and
017696002000.
For AT&T Custom Multipoint service from an AT&T 5GSS switch,, SPIDs are normally in
this format:
01
nnnnnnn
0
nnnnnnn
is a 7-digit telephone number (not including the area code) of the ISDN BRI line.
