To order ISDN service for your Pipeline, follow these steps:
In most cases, the switch will be an AT&T 5ESS or a Northern Telecom DMS-100.
If the switch for your area is an AT&T 5ESS, this will be National ISDN-1 (NI-1), AT&T Custom Multipoint, or AT&T Custom Point-to-Point. If the switch for your area is a Northern Telecom DMS-100, this will be National ISDN-1 (NI-1) or DMS-100 Custom.
Request 2 ISDN telephone numbers and 2 service profile identifiers (SPIDs) for your ISDN line if they are available for your ISDN service.
-- ISDN Service Profile Identifiers (SPIDs)
The AT&T 5ESS switch supports the following types of ISDN service:
If your telephone company uses an AT&T 5ESS switch for your area and offers more than one type of ISDN service, National ISDN-1 is normally the best choice, because it lets you use more of the features of the Pipeline. AT&T Custom Multipoint is the next best choice. You should choose AT&T Custom Point-to-Point service only if no other ISDN service is available in your area. For information on the limitations of AT&T Custom Multipoint and AT&T Custom Point-to-Point services, see "Special issue for AT&T Multipoint and Point-to-Point services" later in this document.
The tables in this section list the proper provisioning settings for each type of service.
Note: Local rules may prevent your telephone company from offering certain features. Because of this, the telephone company may not use all the provisioning settings listed.
The following table lists the provisioning settings for National ISDN-1 (NI-1) service provided by an AT&T 5ESS switch. Your local telephone company can configure your ISDN line using the information shown in the following table or by using the Bellcore S1 translation settings. Some features are set for each of the directory numbers (telephone numbers) for your ISDN service.
The following table lists the provisioning settings for AT&T Custom Multipoint service provided by an AT&T 5ESS switch. Some features are set for each of the directory numbers (telephone numbers) for your ISDN service.
| Provisioning Feature | Setting |
|---|---|
| Term Type | A |
| Call Appearances (CA) | 1 |
| CA Quantity | 1 |
| Circuit Switched Voice (CSV) | 1 per Directory Number |
| Circuit Switched Data (CSD) | 2 per Directory Number |
The following table lists the provisioning settings for AT&T Custom Point-to-Point service provided by an AT&T 5ESS switch. Some features are set for each of the directory numbers (telephone numbers) for your ISDN service.
| Provisioning Feature | Setting |
|---|---|
| Term Type | A |
| Call Appearances (CA) | 1 |
| CA Quantity | 1 |
| Circuit Switched Voice (CSV) | 1 |
| Circuit Switched Data (CSD) | 2 |
Regardless of the type of ISDN service you have, you cannot receive a voice call when there are data calls to two different sites. However, AT&T Custom Multipoint service and AT&T Custom Point-to-Point service have an additional limitation: if you have one of these services, you cannot receive a voice call when both B channels are used for a data call to the same site. Outgoing calls are not affected by this limitation, because they are controlled by the Pipeline rather than by the switch. If you try to make an outgoing call when both B channels are used for a data call to the same site, the Pipeline can borrow one of the B channels for the voice call.
The Northern Telecom DMS-100 supports the following types of ISDN service:
The tables in this section list the proper provisioning settings for each type of service.
Note: Local rules may prevent your telephone company from offering certain features. Because of this, the telephone company may not use all the provisioning settings listed.
The following table lists the provisioning settings for National ISDN-1 (NI-1) service provided by a Northern Telecom DMS-100 switch. Your local telephone company can configure your ISDN line using the information shown in the following table or by using the Bellcore S1 translation settings. Some features are set for each of the directory numbers (telephone numbers) for your ISDN service.
*If you will not use the Conference, Drop, or Transfer features of the Pipeline, this can be any number from 1 to 64.
**Either Electronic Key Telephone System (EKTS) or Additional Call Offering (ACO) must be Yes, but not both. Only one of these two settings can be set to Yes.
***The Notification Busy Limit setting is needed only if Additional Call Offering (ACO) is Yes.
The following table lists the provisioning settings for DMS-100 Custom service provided by a Northern Telecom DMS-100 switch. Some features are set for each of the directory numbers (telephone numbers) for your ISDN service.
*If you will not use the Conference, Drop, or Transfer features of the Pipeline, this can be any number from 1 to 64.

A Service Profile Identifier (SPID) is a number that identifies ISDN equipment attached to your ISDN line. Depending on the type of ISDN service you have, there are one, two, or no SPIDs. When you order ISDN service, the telephone company should give you the necessary SPID or SPIDs, which you then use when configuring your Pipeline.
Note: You normally don't need to know about SPIDs; you simply enter the numbers when configuring the Pipeline. If, however, the telephone company does not provide the necessary SPIDs or provides SPIDs that are incorrect, the information in the following sections can help you explain to the telephone company what you need.
A SPID is normally derived from a telephone number for the ISDN BRI line. It may or may not include the area code, and it may have a special prefix and/or suffix. The SPID formats used by most telephone companies are described in the following sections.
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 these generic SPIDs, which is the same for all switches, is as follows:
For example, if the telephone company 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.
For National ISDN-1 (NI-1) service from an AT&T 5ESS switch, SPIDs are normally in this format:
For example, if the telephone company 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, SPIDs are normally in this format:
For example, if the telephone company assigns the telephone numbers 769-6001 and 769-6002 to the ISDN BRI line, the SPIDs are 0176960010 and 0176960020.
There are no SPIDs for AT&T Custom Point-to-Point service.
For National ISDN-1 (NI-1) service from a Northern Telecom DMS-100 switch, SPIDs are normally in this format:
-- 0, 1, or 2
A different digit is normally used for each of the two SPIDs for the ISDN line.
If it is two digits, it must be one of the following two-digit pairs:
-- 00, 01, or 02
A different pair is normally used for each of the two SPIDs for the ISDN line.
For example, if the telephone company assigns the telephone numbers 769-6001 and 769-6002 to the ISDN BRI line, 01 and 02 are the SPID suffixes, and 00 is the two-digit code for both SPIDs, the SPIDs are 51076960010100 and 51076960020200.
For DMS-100 Custom service from a Northern Telecom DMS-100 switch, SPIDs are normally in this format:
-- 0, 1, or 2
A different digit is normally used for each of the two SPIDs for the ISDN line.
If it is two digits, it must be one of the following two-digit pairs:
-- 00, 01, or 02
A different pair is normally used for each of the two SPIDs for the ISDN line.
For example, if the telephone company assigns the telephone numbers 769-6001 and 769-6002 to the ISDN BRI line, and 00 and 01 are the SPID suffixes, the SPIDs are 510555121200 and 510555121201.
