970 ISDN Telephone

Your new Lucent Technologies 970 Telephone is
developed for use with ISDN service. ISDN (Integrated
Services Digital Network) is one of the ways you can
get local telephone service from your local provider.
ISDN service has been around for a while and is
extensively used by large companies. Now the service
is affordable and attractive to small companies and
residences with telephone needs that stretch the limits
of traditional service.

Before you can use your telephone, you need to apply
for ISDN service from your local telephone service
provider. There are various packages of service
available, and you need to consider the differences
carefully.

You have a long list of features available to you with
your combination of ISDN service and your Lucent
Technologies ISDN 970 Telephone. Together they give
you an ISDN System that can be customized to fit
your needs. Because of these capabilities, there are a
few steps to be completed to set up your system, after

which you can customize your system as much or as
little as you require. (See the Installation and Setup
Manual.)

Here are a few terms you will want to understand as
you customize your ISDN system.

Call Appearance: With traditional telephone service,
you had a “telephone line” on which you could have a
single “call appearance.” Then came call waiting, and
you had two call appearances per telephone line: you
talked on one call appearance and the other call came
in on the second. You could toggle back and forth
between the two call appearances by putting one call
appearance on hold. ISDN service can provide you
with multiple call appearances.
