Information required from the ISDN BRI provider
If a Net/BRI module (MX-SL-8BRIN) is installed, your ISDN BRI provider must provide you
with the following information:
•
The phone 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.
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
