ISDN BRI, ZEPHYR, AND YOU
This section applies to users in North America and is intended to help you when
it comes time to order your ISDN line. We assume you have read the description of
ISDN in the manual and are familiar with ISDN’s basic concepts. If you have not read
that section, doing so now will help you better understand the information that follows.
ISDN (Integrated Services Digital Network) is the information superhighway at your
front door. Because ISDN has only been recently introduced, there is a great deal of
confusion about what it is and how to get it. If you know who to call and provide them
with complete information, the ISDN ordering process can be simple and
straightforward. This guide takes you through the process step- by- step. Telos
Customer Support is available by phone or fax to answer any further questions you may
have.
From the perspective of the telephone network, each channel appears to be a separate
line with it’s own number and independent dial- out capabilities. Since each has to be
dialed or answered separately, they appear to be “lines” to users also. We refer to a B
channel as a “line” on the Zephyr menus and LEDs.
The Zephyr’s internal interface (sometimes called by it’s generic name “Terminal
Adapter”) is used to connect to digital ISDN telephone lines. It easily adapts to the
various types of service offered by the range of Central Office (CO) switches installed by
telephone companies in the USA and Canada.
Ordering ISDN
Dealing with the Phone Company
As is often the case when broadcasters interface with phone people, the lines of
communication on ISDN can get a little tangled.
The first order of business is to find someone who knows what ISDN is. While your
usual account agent will be the normal entry point, you will probably be talking to a
number of phone people before you find one who understands your needs.
Some of the regional Bell companies offer a single point of contact number for switched
digital services. Note that in many cases the phone company will need to do a “loop
qualification” (line loss test) from your site before they can verify that ISDN will be
available. Some telephone companies use “resellers”. If this is the case you should
inquire what experience this reseller has with installing ISDN for audio codecs.
Here are some contact numbers we use – if you have particularly positive or negative
experiences with these offices, please let us know.
