This chapter was designed to be a guideline for ordering ISDN service in the United States.
For BRI ISDN Service:
If you are using NI-1 lines, try using
EZ-ISDN Codes to order BRI service. If your service provider
does not support EZ-ISDN Codes, try using the NI-1 ISDN Ordering Codes .
If your service providers does not support either types of codes, or, if you are using a non-NI-1 line,
refer to
Ordering BRI ISDN Lines using Provisioning Information .
For PRI ISDN Service:
If you are using PRI lines, refer to
Ordering PRI ISDN Lines .
O RDERING NI-1 L INES U SING EZ-ISDN C ODES
If you are using a NI-1 switch type and your service provider supports EZ-ISDN codes, we
recommend using the EZ-ISDN 1 code. EZ-ISDN 1 provides alternate circuit-switched voice/data
on both B-Channels. There is a CSV/D terminal associated with each of the B-channels.
The B-channels will be given a unique primary directory number capable of making/receiving one
circuit-switched voice or circuit-switched data call. Additionally, calling line Id is also supported.
O RDERING NI-1 L INES U SING NI-1 ISDN O RDERING C ODES
If you are using a NI-1 switch type and your service provider supports ordering codes, we
recommend NI-1 ISDN Capability Package I. This package includes circuit-switched data on two B
channels. Data capabilities include Calling Line Id. No voice capabilities are provided. The lack of
voice feature may save you money. However, package K or M will also work.
O RDERING BRI ISDN L INES USING P ROVISIONING S ETTINGS
If your service provider does not support EZ-ISDN or ISDN Ordering Codes, or you are using a
non-NI-1 line, use this section when ordering your BRI ISDN line.
When the phone company installs the line, they assign it certain characteristics. These are different
depending on the type of ISDN switch to which the line is attached. AT&T’s 5ESS NI-1 and
Northern Telecom’s DMS100 NI-1 are among the most popular.
When ordering an ISDN line, there are general steps to follow that apply to all types, and there are
steps specific to your line type. The general steps to follow are:
1. Contact your service provider to determine the type of available switch.
2. Ask your service provider for the available types of ISDN services.
