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.
Page 9
Fujitsu SRS -1050 (
Starting Over
If for any reason you become confused while setting up a local feature in
menu mode, you can always press REG, sof tkey 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 circuitswitched or packet-switched data services. There is also one "D"
channel, at 16,000 bits per second, for network signaling and packetswitched data service. The combination is often referred to as "2B+D", or
the Basic Rate Interface (BRI).
Page 10
( Fujitsu SRS-1050
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.
Page 11
Fujitsu SRS -1050 (
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.
Page 12

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.

SRS -1050 Overview ( Chapter 1
Special features, such as call
forwarding, are provided by the
ISDN network. These features are
selected by your System
Administrator and assigned to
buttons on your phone during
installation.
In order to simplify ordering and
line installation, Fujitsu has
included pre-set assignments for
some of the most frequently used
network based features. See
Appendix A for these
assignments.
You use Call Appearance (CA) or
Directory Number (DN) buttons
to handle your calls, as described
in the next two sections. Pressing
a Call Appearance button
connects you to a phone line.
This line can be idle with dial tone
for making an outgoing call, a line
containing an incoming call, or a
call on hold.
The upper right button is
normally used as a MIC-OFF
function key, and is set this way
when the unit is shipped. When
pressed, the MIC-OFF key turns
red and mutes the speaker or
handset microphone, allowing
you to hold a private
conversation. See the section
Activating the MIC-OFF key in
Chapter 3 for the procedure to
deactivate this feature. You can
then reassign this button as a
one-touch button or to some
other local feature.
If you are on an active call,
pressing a Call Appearance
button automatically puts the call
on hold. This feature is called
autohold.
Multiple Directory Number
Appearances
Each SRS-1050 associates its
primary Directory Number with
multifunction button 1. Multiple
appearances of the same
Directory Number are always on
adjacent Call Appearance
buttons. (The button at the end
of a row is "adjacent to" the
button beginning the next row
up.)
Note: This guide uses the term
directory number appearances
to refer to directory numbers
that appear on more than one
Call Appearance button. The
Nortel term for Call
Appearances that can handle
more than on call is Additional
Functional Calls.
A telephone can also be
assigned additional directory
numbers. Each such number
can then be assigned to
adjacent buttons as well to
allow multiple call handling on
that line.
Page 1-6
Chapter 1 ( SRS-1050 Overview
Any Directory Number assigned
to one phone can also appear on
another phone, which can then
share the use of that line.
Figure 1-4 shows an SRS-1050
whose primary Directory Number
is 747-3456, with two additional
Call Appearance buttons
assigned that same number. The
telephone's secondary line is 7477890, which has two appearances.
In the illustration, this set also
has a button assigned to the
number 747-3482. This could, for
example, be a shared line using
someone else's primary Directory
Number.

Assignment
Call Handling Example with
Multifunction Buttons
Suppose your Directory Number
is 747-3456, and the first three
multifunction buttons on your
SRS-1050 have been assigned
that number.
What does it mean to have three
Call Appearance buttons
assigned to one directory
number? It means you can have
up to three calls at the same time
using that single Directory
Number, though you can talk on
only one at a time.
For example, if you have no calls
in progress and someone di als
747-3456, your telephone rings
and the LED for the first Call
Appearance button associated
with 747-3456 flashes green. You
can answer the call by pressing
that Call Appearance button and
picking up the handset. (The LED
turns steady red.)
After answering the call, you can
press the second 747-3456 Call
Appearance button to originate
another call. The first call is
automatically put on hold. If
another call comes in, you can
press the third Call Appearance
button representing 474-3456 to
answer the third call. The second
call is also placed on hold.
You would then have three calls
on your 747-3456 Directory
Number. Only then is your 3456
number "busy", that is, when all
three assigned Call Appearance
buttons are in use.

the following screen:
For an incoming call, the calling
party's number appears if the

INTRODUCTION TO
VOICE FEATURES
The Fujitsu SRS-1050 provides
superior call-handling and
simultaneous voice/data
communications. It is one of the
family of Fujitsu Integrated
Services Digital Network (ISDN)

For the familiar tasks of dialing,
holding, and answering calls, this
phone operates like others you
have used. However, it also
includes the many special
features explained in later
chapters.

to do if you are not talking on
another call, and what to do if you
are talking on another call.
• Switching between handset
and handsf ree modes
• Placing a call using the

To make the best of handsfree
mode, you should be sure that the
MIC-OFF key feature is active on
the button at the upper -right of
the array. This feature is set
active by default when you
receive your SRS-1050. If for
some reason this feature is not
active, see “Activating the MICOFF Key” in Chapter 3 for the
activation procedure.
(See also "Handsfree, Handse t,
and Headset Modes", in Chapter
