Appendix
Appendix F: Ordering ISDN BRI (2B+D) Lines
Two ways to specify your ISDN line configuration to your service provider are:
• Use ISDN
ordering codes
where the user and the Local Exchange Carrier (LEC) or
Internet Service Provider (ISP) use common nomenclature to describe elements of
service.
service.
• Use a
building block approach
where the naming conventions are not standard, and
the user and provider must establish a set of provisioning options.
Several lists of contacts for ISDN service providers are located at the end of this
appendix.

Loop Qualification
The first step in ordering (
provisioning
) an ISDN BRI line is to contact your LEC and
verify ISDN BRI loop availability in your location. There is a distance limitation of
approximately 2 miles (1800 Kf) from the BRI loop. Each request for BRI is handled on a
case-by-case basis. Once qualified, the LEC requires information on the type of
equipment and protocol used. Most ISDN BRI is configured as
approximately 2 miles (1800 Kf) from the BRI loop. Each request for BRI is handled on a
case-by-case basis. Once qualified, the LEC requires information on the type of
equipment and protocol used. Most ISDN BRI is configured as
voice and data.
(Since
LEC network primarily is analog, ISDN digital technology converts the digital signal into
analog, transports it over its analog lines, and then re-converts it into digital data at the
other end). As a general procedure, when ordering an ISDN BRI (2B+D) line:
analog, transports it over its analog lines, and then re-converts it into digital data at the
other end). As a general procedure, when ordering an ISDN BRI (2B+D) line:
1. Plan ahead. The BRI line order may take four weeks or more to get provisioned.
2. Contact your LEC representative early in the process to ensure ISDN BRI loop
availability for your location.
3. Provide the LEC representative with
• Your correct address for the BRI service.
• The type of equipment (e.g., Multi-Tech ISIHI-2S) and the protocol specifications
it supports. Use the
ISDN BRI (2B+D) Line Ordering Checklist
provided later in
this document for protocol specifications.
• The type of jack required by the ISIHI-2S (i.e., RJ-45 male 2-wire U Basic Rate
Interface).
4. Wait for installation notification from the LEC. Ask the LEC representatiave what type
of switch is used (AT&T 5ESS and NT DMS-100 are most prevalent).
5. Ensure availability of an
auxiliary
analog line (if you plan to use the TA’s
AUX
RJ-11
analog connector for a standard telephone connection). Make sure you have a 115
VAC (60 Hz) power outlet near your computer for the TA’s two-prong outlet-mounted
power transformer.

6. Record all of the information provided by your LEC.
