SPIDs for AT&T 5ESS switches
If your ISDN BRI line comes from an AT&T 5ESS switch operating in Multi-Point (MP) or
National ISDN-1 (NI-1) mode, each SPID has the following format:
01 NNNNNNN 0 TT
where:
•
NNNNNNN is the 7-digit phone number of the ISDN BRI line.
•
TT is the 2-digit TID (required only for NI-1).
The TID can be a value from 00 to 62. It is assigned by your carrier. Ascend recommends
that you use 00 as the TID for all SPIDs.
For example, suppose that 555-1212 is the 7-digit phone number of an ISDN BRI line using
Multi-Point mode. The telephone company gives you the following SPID:
0155512120
Note: Because Multi-Point mode is not an NI-1-compliant, no 2-digit TID is required.
Now, suppose that 555-6001 and 555-6002 are the 7-digit phone numbers of an ISDN BRI line
using NI-1 mode. You choose TID=00 for both numbers and the telephone company gives you
the following SPIDs:
015556001000
015556002000
If your ISDN BRI line operates in Point-to-Point (PTP) mode, SPIDs are not required.
SPIDs for Northern Telecom DMS-100 switches
If your ISDN BRI line comes from a Northern Telecom (NTI DMS-100) switch, each SPID
has the following format:
AAANNNNNNN SS TT
where:
•
AAA is the 3-digit area code of your ISDN BRI line.
•
NNNNNNN is the 7-digit phone number of your ISDN BRI line.
•
SS is the SPID suffix, which can contain zero, one, or two digits as follows:
–Empty
– 1 and 2 for each ISDN BRI line
– 01 and 02 for each ISDN BRI line
•
TT is the 2-digit TID (required only for NI-1 [PVC=2]).
The TID can be a value from 00 to 62. It is assigned by your carrier. Ascend recommends
that you use 00 as the TID for all SPIDs.
For example, suppose you are using Northern Telecom in NTI Custom mode [PVC=1]). The
phone number of your ISDN BRI line, including the area code, is 415-555-1212. The
telephone company gives you the following SPID:
415555121201
