Preface
This guide provides descriptions and procedures for using Fujitsu's
Digital Set Feature Phone, called the SRS-1050, when it is attached
to an AT&T 5ESS switch.
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
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.

Conventions and Layout
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. This section describes features you may find
surprising.
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.

Fujitsu SRS-1050 (
Page 10
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 fifteen 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.

(Fujitsu SRS-1050
Page 11
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 data model, 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.

Fujitsu SRS-1050 (
Page 12
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 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 have a
data terminal adapter installed. The supporting network data
features must also be assigned to the line.
Multipoint configurations
In older phone installations, most phone connections are point-to-
point. Each phone in a point-to-point configuration requires a
separate line into your building. However, many service providers
now offer multipoint configurations as a subscription option. ISDN
supports both point-to-point and multipoint operation. 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.

(Fujitsu SRS-1050
Page 13
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 Chapter 3.
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
An important person for you to know is your System Administrator,
who may be your phone company representative or a member of
your telecommunications department.
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.

SRS-1050 Features
1) Handset/Headset. Use the
familiar handset, the speaker and
microphone, or a headset to make
or answer calls.
2) 9) Speaker/Microphone. The
speakeris located directly under
the handset. In handsfree
operation, it lets you hear the
other parties in a telephone call.
The microphone on the front edge
of the front edge of the phone
picks up your voice, unless
switched off with the MIC-OFF
key.
3) Numeric Keypad. You use
these twelve keys to enter the
number you are calling or the
special characters *(asterisk) or
#(pound sign).
4) Display. The display shows
call information such as the
telephone number of the other
party, call duration, and time of
day.
5) Softkeys/KEY MENU. Four
buttons below the display with
changeable functions. The KEY
MENU key displays the current
functions on line 2 of the display.
6) Multifunction buttons. These
buttons are assigned to Call
Appearances, one-touch
numbers, or local features.
7) Volume/Contrast buttons.
Increase or decrease display
contrast (when no Call
Appearance is active), or speaker
volume (when a CA is active).
8) Function keys. Single-touch
keys for ISDN features (see
Function Keys).
