channel). For DMS and NI-1 switches, the BRI line has two SPIDs, and two phone numbers. Note that either SPID can use either bearer channel. There is no one-to-one correspondence. You must enter the number of digits to verify (starting at the right-most digit), so that when the system receives a phone call it can determine on which bearer to accept the phone call. The maximum number of digits should be 7, which is the default value in most cases.

SERVICE PROFILE ID (SPID)

For basic rate lines only. SPIDs are only required for DMS100 and NI-1 switch types. A SPID is a number that identifies ISDN equipment attached to your ISDN line. Depending on the type of ISDN service you have, you may have one, 2, or no SPIDs. When ordering your ISDN service, your service provider should supply you with SPID information.

A SPID is usually derived from the ISDN line’s telephone number. It may include the area code. It may also include a special prefix and/or suffix (for example, a prefix of 9 for Centrex lines).

The SPID format for AT&T 5ESS NI-1 Service is: 01nnnnnnn0tt

where nnnnnnn is the 7 digit phone number (no area code) of the BRI line tt is a user assigned 2 digit terminal Id code, 00 is normally used

The SPID format for AT&T 5ESS Custom Multipoint Service is: 01nnnnnnn0

where nnnnnnn is the 7 digit phone number (no area code) of the BRI line

The SPID format for Northern Telecom DMS-100 NI-1 Service is: aaannnnnnnss

where aaa is the 3 digit area code of the BRI line nnnnnnn is the 7 digit phone number of the BRI line

ss is the SPID suffix (optional, 01 can be used for one number, 02 for the other)

The SPID format for Northern Telecom DMS-100 Custom Service is: aaannnnnnnsstt

where aaa is the 3 digit area code of the BRI line nnnnnnn is the 7 digit phone number of the BRI line

ssis the SPID suffix (optional, 01 can be used for one number, 02 for the other)

ttis a user assigned 2 digit terminal Id code, 00 is normally used

If the DMS100 requires two data links per line, it will also have two “Service Profile Identifiers (SPIDs)” and two directory numbers. If the NI-1 has two data links per line, two SPIDs and two directory numbers are required, otherwise one SPID and one directory number is required. A SPID is paired with a directory number to define a data link.

Note that if your line does not require a SPID, enter a SPID value of 0.

DIRECTORY NUMBERS

If your line requires a SPID (if you entered a SPID with a value other than “0”), you will be required to enter the site's directory number. That directory number is paired with the above entered SPID for this data link. The directory number is used to match an incoming call with the correct data link.
