Preface
This guide provides descriptions and procedures for using Fujitsu's
Digital Set Feature Phone, called the SRS-1050, when it is attached to a
switch supporting National ISDN.
This guide is for anyone interested in using the SRS-1050 to gain the
benefits of the combined voice and data network capabilities of ISDN
technology.
Read the sections that follow for information on:
•Using this guide efficiently
•Special features of your ISDN telephone
•Background on ISDN technology
For assistance ordering ISDN service from your local service provider,
see Appendix A.
HOW TO USE THIS GUIDE
This section can help you make the most efficient use of this guide. The
section describes the overall organization, aids to finding information,
and conventions.
Organization
This guide is organized in the following chapters:
Chapter 1 has illustrations to introduce the physical layout of
the SRS-1050. It also describes the features and
functions of its components.
Chapter 2 describes use of the basic voice services, such as
placing and receiving calls and using the
speaker/microphone (handsfree mode).
Chapter 3 explains how to set up SRS-1050 features such as
one-touch buttons, unanswered call logging, and the
calendar/clock.
Chapter 4 explains how to use the data terminal adapter to
place or receive data calls.

In procedures, the required actions are noted, with the buttons you press
in capital letters, such as HOLD or REDIAL.
Other important words, such as messages that appear on the display,
also appear in CAPITAL LETTERS.
Menus or screen displays appear as text in boxes.

Helpful Tips About Your SRS-1050
Because ISDN technology is new, some features of your SRS-1050 may
be unfamiliar.

Softkeys
The softkeys are the four keys located just below the display. When you
press the KEY MENU button to their right, function labels appear on
line 2 of the display.
UNA DATA CLEAR REG
1 2 3 4
Key Menu
Standard Softkey Layout
(The DATA softkey label appears only if you have the data model.)
Note: Softkey 1 also serves as the ENTER key (for entering
information as indicated in this User Guide).
Softkeys are a way of simplifying the phone and still supporting the
richness of ISDN features. These keys assume different functions
depending on the feature you are using, thus avoiding the need for a
large number of permanent function keys.
You can display the labels at any time without affecting the tasks you
are performing. The labels do not, however, have to be displayed for
these keys to work.
Timeouts
When you are setting up local features as described in Chapter 3, some
of the data entry displays have built-in timers. If you do not enter
information within six seconds, the display reverts to the menu for
selecting the feature you were setting up. You must reselect the feature
and start again.

Starting Over
If for any reason you become confused while setting up a local feature in
menu mode, you can always press REG, softkey number 4, to return to
the setup menus and start over.
Phone Operation
The following two features of ISDN phones may be different from what
you are used to:
Dialing 9. When you dial for an outside line (usually by pressing 9),
you do not hear a pause and a second dial tone. You can begin dialing
the telephone number immediately.
Onhook dialing. You can dial a number before you get a dial tone. The
number you dial appears on the display and remains there for three
minutes. When you lift the handset and press an idle Call Appearance
button, or press the SPEAKER button for handsfree mode, the phone
initiates the call automatically.
ISDN CONCEPTS: INTEGRATED VOICE AND DATA
ISDN stands for Integrated Services Digital Network, which provides
many voice and communication features. (The SRS-1050 data features,
available with the optional data terminal adapter, are described in
Chapter 4, "Data Operation".)
The basic ISDN service provides two 64,000 bits per second "B"
channels for voice or data communications. Each B-channel can
support circuit-switched or packet-switched data services. There is also
one "D" channel, at 16,000 bits per second, for network signaling and
packet-switched data service. The combination is often referred to as
"2B+D", or the Basic Rate Interface (BRI).

Voice Features
The voice features of an ISDN telephone have several advantages:
•They allow your telephone to handle multiple calls simultaneously,
receiving calls while keeping others on hold.
•They also permit a call coming in to a single directory number to
ring more than one physical telephone. This feature facilitates call
handling within a group.
•They provide easy-to-use-access to powerful features such as call
conferencing and call transfer, to enhance your productivity.
•They allow the incoming directory number to be displayed if it is
available.
Data Features
The optional data features of the SRS-1050 include the following
capabilities:
•Communication on the D-channel using packet switching with an
asynchronous RS-232 terminal at terminal speeds up to 19,200 bits
per second.
•Communication on the B-channel using circuit switching with an
asynchronous RS-232C terminal at speeds up to 38,400 bits per
second.
In order to do data communications, your phone needs to be equipped
with a data terminal adapter. The supporting network data features
must also be assigned to the line.

Multipoint configurations
In older ISDN installations, most phone connections are point-to-point.
Each phone in a point-to-point configuration requires a separate line
into your building. However, most service providers now offer
multipoint configurations as a subscription option. In a multipoint
configuration, up to eight devices (digital sets and/or terminal adapters)
can be connected to a single line. For example, your company could
connect two digital sets and two data terminal adapters to a single line.
The two digital sets could each use one B-channel for voice
communication, and the data terminal adapters could use the D-channel
for packet-switched data calls.
Multipoint operation goes on behind the scenes. The only time you
would be aware of it is if you get "blocked" from using a line. If more
than two users bid for the two B-channels at the same time, the message
B-CHANNEL BUSY appears. Talk to your System Administrator if you
get this message frequently.
SPID
For your SRS-1050 to work on a multipoint line, it must have a valid
Service Profile Identifier (SPID). The SPID number is usually entered
when the SRS-1050 is installed. So if your digital set already has a
SPID number, you don't have to reenter it. If you do need to enter a
SPID number, you can find out what it should be from your System
Administrator or service provider. For the procedure to enter a service
profile identifier, see Appendix B.
CAUTION: Once the SPID number is entered, don't change it unless
your System Administrator tells you to do so. Your SRS-1050 won't
work without the correct SPID number. If the SPID number is
wrong, the set displays the message SPID NG. (The message is
redisplayed a second time if the data terminal adapter SPID is also
invalid.) Enter the correct SPID number and you'll get the normal
dial tone.

System Administrator
ISDN is very flexible in allowing businesses to customize how it works
to meet their specific needs. This User's Guide refers you to your
System Administrator if a customized option may have been chosen
during installation.
Your System Administrator may be your phone company representative
or a member of your telecommunications department.
Call Appearance Preference
The SRS-1050 allows you to specify which Call Appearance button it
selects when you go offhook (lift the receiver or press SPEAKER). You
have four choices:
•Primary line preference. The SRS-1050 always selects button
number 1, the Call Appearance associated with your primary
directory number.
•No preference. The SRS-1050 does not automatically select any
Call Appearance button when you go offhook. You must press the
button you wish to be connected to either before or after you go
offhook.
•Ringing line preference. The SRS-1050 selects the Call
Appearance button that is ringing with an incoming call. You are
immediately connected to the call.
•Idle preference. The SRS-1050 selects an idle Call Appearance.
For more details about Call Appearance preference, see "Selecting CA
Preference," in Chapter 3.
