PREFACE
This manual gives a description of the installation, testing and firmware loading of the SOPHO
Supervisor Model 25 (SV25) and SOPHO SuperVisor Model 35 (SV35).
Information contained in this manual is intended for Customer Engineers, responsible for the
installation and maintenance of the SuperVisors model 25 and 35.
Documentation references:
- SOPHO SuperVisor Model 25 or 35 User Guide.

1. INTRODUCTION
1.1. GENERAL
The SOPHO SuperVisor Model 25 and 35 (SV25 and SV35) are operator consoles which can
be applied for the complete range of SOPHO-S and SOPHO iS3000 series.
Model 25 has less functionality than model 35. Model 25 is equipped with an analogue interface
and an S0bus interface. You can choose the interface which is required for your system. Model
35 is equipped with only an S0bus interface.
The functionality of model 25 is depends on the functionality which is available via the system
interface. Therefore, be aware of the fact that the available functionality on model 25 differs
for the two types of interfaces. In this document a distinction is made between model 25 on
the analogue interface and model 25 on the S0bus interface. The following references are
made:
- Model 25-S0, if used with an S0bus system interface.
-Model25-A, if used with an analogue system interface.
Model 35 is equipped with only an S0bus system interface.
In the table below an overview is given of the SuperVisor consoles in relation to the systems.
For the model 25-A the interface circuit in the system is also given in the table. For Model 25-
S0and model 35 the interface in the system is always a DTX-I, a DLC-C/D/U or a DOC in
conjunction with a PNT1 (version 2).

WARNING: DO NOT CONNECT MORE THAN TWO SV25/35 PER BOARD IN
THE IS3000 (NOT RELEVANT FOR MODEL 25-A)
DO NOT USE THE REMAINING CIRCUITS OF THE BOARD FOR
CSTA INTERFACES, TRUNK LINES OR ACD AGENTS; USE THOSE
CIRCUITS FOR NORMAL ISDN EXTENSIONS ONLY.
DO NOT CONNECT MORE THAN TWO SV25/35 PER PM IN THE
IS3000.
Table 1-1 Overview of SOPHO SuperVisors in relation to ISPBX System Types.
The S 0 bus interface protocol is 1TR6 (+proprietary elements) with TMP protocol.
The consoles provide all the basic call handling facilities of an operator desk. In addition to this,
features and facilities are provided to improve the operator and system administrator
efficiency. The system administrator can be e.g a communications manager or operator
supervisor.
Each user is able to switch the SOPHO SuperVisor to night condition by pressing a certain key.
The system is switched to the night condition when all the operators are switched to the night
condition. Switching the console to day condition can be password protected.
1.2. FACILITIES
Model 35 offers a great number of facilities. Depending on the System Software in the ISPBX,
the SuperVisor facilities can be fully used, or used with a limited capacity/functionality.

Model 25 offers a reduced set of facilities, in comparison with the facilities in the model 35. In
the table below an overview is given of the facilities which are present in model 25 and model
35. Note that in the table also a column is defined which denotes the facilities of the SV30.
The SV30 is the predecessor of model 35.
In the table, Call handling is not mentioned as a facility of the SuperVisors. The possibilities in
call handling depend to a certain degree on the software in the system.

Table 1-2 SuperVisor Facilities.
The following gives a short description of the facilities which are mentioned in the table above.
• Abbreviated dialling
You can store numbers in a memory and dial these numbers by means of short codes.
Also you can save and repeat the last dialled number.
• Alarm Monitoring
If a fault condition occurs in the system, it is displayed on the Supervisor display. By means
of Operator Desk Commands the alarm buffers in the system can be read out. These
contain a history of alarms with qualifiers and additional information.
• Auxiliary output for Recorder control
By means of this auxiliary output a recorder can be switched on when the handset is
activated to handle a call.
• Braille Interface
The Braille interface is a V.24 interface, which can be used to connect a Braille Unit for
visually handicapped operators. This unit represents the information of the display in

braille format.
• Call Charging Display
The operator can mark an outgoing call for call charging. After completion of the call the
cost (number of metering pulses or call duration) can be displayed (iS3000 facility). If the
call is free of charge, it is also displayed.
• Calling Number Display (In case of ISDN trunks)
If an ISDN directory number is passed on by the public exchange to the ISPBX, this calling
number is displayed on the display of the console.
• Communication Interface
The communication interface is a V.24 interface which can be used for the following
purposes:
- Directory up/down loading;
- Speed dialling key data and Status Monitoring data up/down loading from PC;
- Dialling;
- Braille interface;
- Program downloading.
•DemoMode
Various windows (e.g. name display) are standard available for training, and demonstration
of the features of the console. The Demo Mode can only be used if the console is set 'Out
of Service'. Model 25 has also the facility to demonstrate the VPU (Voice Processing Unit)
for call handling.
• Directory Handling
Directory handling is a feature of model 35. It is equipped with an internal directory
memory of 50 kb. The directory information (name, DNR etc.) is stored according to an
algorithm. Therefore it is not possible to denote the maximum number of entries. If all
number and branch information is unique for 600 entries of 80 characters, all entries can
be stored. In case the entries are 40 characters average (typical value), at least 1200 entries
can be stored. In practice more entries can be stored as result of the storage algorithm.
• Directory Up/downloading
The directory data can be up/down loaded to/from a PC.
• Enhanced Keyboard Layout
Model 35 has a alpha numeric keyboard layout. This means that the keyboard can also be
used to enter names messages etc. Two different keyboards are available:
- International (QWERTY standard);
-German(QWERTZstandard).
The tops of the keys on the keyboard are different. A number of them are hollow and a
number of them are flat according to a logic pattern. This allows easy orientation for
visually handicapped users.
• Firmware Uploading
Initially the factory stores the firmware in the FEPROMS. In case of a firmware update or
in case of firmware problems, it can be uploaded from a PC via the V.24 interface to the

9
console. A software tool is available which must be installed on a PC. This tool requires
operating system MS-DOS and can be installed on IBM compatible PCs (e.g. XT, AT, 386,
486 etc.).
• Fully Symmetrical Call Status Information
If the System Software supports this functionality, call status (e.g. diverted, alerting,
answered) is displayed for the 'A' party as well as the 'B' party. If the System Software does
not support this functionality, only the status information of one party is displayed. This is
called asymmetrical call status display.
• Individual Monitoring
The operator can mark an external call for special attention. This can be e.g. an important
customer or a long distance call who/which does not want to be kept waiting. If a call is
marked, it is indicated on the display in such a way that the operator is reminded that this
call is waiting and needs attention.
•GiveaLine
The operator can give a line to an extension user who wants to dial an external number
himself, but is not allowed to do that.
• Messaging
Model 35 supports end-to-end messaging, as it is available for the SOPHO-SETs. This
facility can be used in two different ways:
-Freemessaging
This is done by sending a short (ASCII) message to an extension, which is stored (in
that receiving set) together with the date, time and originators identity.
When the Supervisor dials a SOPHO-SET and the SOPHO-SET is ringing, it can send
and receive messages. Also in speech connection the SOPHO-SET can exchange
messages with the SuperVisor model 35.
- Message receiving
When an extension is dialled from the console and a message is stored in the
extension, the message is displayed immediately at 'number complete'. The message
is displayed on the dialogue line on the display.
e.g. An extension user programs the message "Holiday" on his/her set. When the
operator attempts to make a call to this extension the message will be displayed on
the display of the SuperVisor console.
As soon as a key is pressed, the message is automatically removed from the dialogue
line and deleted.
In case the operator is in the 'softkey' mode (special mode to access configuration data
in the console) the message will be lost.
• Password Protection
Unauthorised use of the model 25-S0and model 35 is prevented by password protection.
Password protection is based on the password protection structure in the system.
Therefore it depends on the software package in the system, how the password
mechanism is implemented.

10
For systems with SSW 300, this means that the operator passwords will be validated by
the CPU of the ISPBX. More than one password can be specified per console, which
means that each operator can have it's own password. On the console, passwords can be
entered, updated and deleted.
If a password has been forgotten a new password can be assigned to the operator DNR
(or to a USIN, User Identification Number) with an OM command.
For systems with SSW 735, 740 and 8xx the password is defined in the signalling data. If
more than one password per system is required, more signalling groups have to be created
each containing its own password. These signalling groups can be assigned to the different
Supervisor circuits.
• Queues
Model 25 and model 35 are able to handle the queue structure as defined in the system.
• Series Call
The operator can connect an external party to several internal parties in series.
• Speed Dialling Keys (only model 35)
The operator can program the 12 keys of the softkey menu with important numbers (e.g.
alarm and emergency numbers). By pressing the 'speed dialling menu' key and after that
one of the 12 pre-programmed softkeys a call is setup.
• Status display
The status (with busy indication) of extensions can be displayed in pages of 100 extensions.
By means of the keys SD1, SD2 and SD3 the pages 1, 2 and 3 are selected. By pressing
'Shift' SD1, 'Shift' SD2', or 'Shift' SD3 the pages 4, 5 or 6 are selected. The DNRs of the
extensions are ordered on the display in 10 rows of 10 extensions, in such a way that the
Least Significant Digit (LSD) of a DNR is not shown. If (during programming) in a DNR the
LSD is left out, that (incomplete) DNR applies to ten DNRs. In the field behind every
(incomplete) DNR, the status of the 10 extensions is displayed in the following way:
- last digit of the extension normal video : extension is ringing.
- last digit of the extension in inverted video : extension is busy or off hook.
- full stop '.' displayed in stead of the last digit : number unobtainable (not existing
extension number, extension out of service).
Also a row of ten trunk lines can be monitored, instead of a row of ten extensions.
• Voice Synthesis for Instruction
Voice synthesis for instruction is build-in in the console. The console generates a voice
signal if a key is pressed. By this means a visually handicapped operator can learn to locate
the functions of the keys.
• Voice Synthesis for Call Handling
Model 25 is able to do 'call handling' voice synthesis for visually handicapped operators.
Model 35 does not support Voice Synthesis for Call Handling but a braille unit is used to
communicate with the visually handicapped operator. Model 25 is not able to control a
braille unit.
A large number of displayed items on the display are converted to spoken messages.

11
The following languages are implemented in model 25-A:
- English
-Dutch
-German
-French
-Danish
- Italian
-Spanish
-Portuguese
-Swedish.
The language is the same as for the display. This can be selected by means of the soft key
menu.
1.3. HARDWARE
1.3.1. General
The consoles are based on the 68302 CPU. The firmware is stored in FEPROMs. Firmware is
uploaded from a PC to the console via the V.24 interface. Also the directory data is stored in
the FEPROM.
As result of the FEPROMs the console is not equipped with a battery for RAM backup
purposes.
The consoles are equipped with the following interfaces:
-S
0bus connection for both models and an 'Analogue Operator Interface' connection for
model 25;
- Recorder output (analogue signal and control);
- Announcer interface (to control up to 4 announcers);
- V.24 connector for:
- Braille interface
- Downloading firmware
- Up/down-loading directories
- Status monitoring
- Speed dialing.
- Connectors (left and right side) for headset/handset.
-Buzzeroutput.
The analogue interface on model 25 is the same as the analogue interface at the SV20.
Therefore it can be connected to the system types as denoted in section 1.1. The S0bus
interface of model 25 and model 35 can only be connected to a DTX-I or PNT1 (version 2).

12
In the interface only one B-channel is used. The D-channel is used for signalling information.
The consoles require 2,5 Watt power from the S 0 bus. This means that no power is left to
connect other terminals to the S0bus. The other B-channel is therefore not available to
support other terminals on the S0bus.
The recorder output comprises an audio output (same audio as on the handset) and a control
signal to switch on the recorder if a call is handled.
1.3.2. Braille Unit
Model 35 has an interface to connect a braille unit. A braille unit is defined for this purpose.
The braille unit must be connected to the V.24 interface. This means that if the braille unit is
connected, the interface cannot be used for other purposes. Some pins of the V.24 interface
on model 35 are also used for signalling purposes (e.g. signalling to an announcer). Therefore
a special cable is available which is equipped with at one side a male 25p D-connector and at
the other side a female 25p D-connector + a female 9p D-connector. (The female 9p D-
connector is compatible with the 9p D-connector on the SV30.)
1.3.3. Exchange Name Announcers
An exchange name announcer can be connected to the system via the audio input connectors
at the back. With two control (address) outputs up to four name announcers can be selected
for an incoming call. One trigger signal is present to start the announcer/announcement.
1.3.4. Recorder
A voice recorder can be connected to the Supervisor for voice registration of incoming calls.
A control signal is available to switch the recorder on or off.
1.3.5. Buzzer
The buzzer output is a relay contact which is closed when the buzzer is activated. This allows
the connection of an external buzzer.

13
2. INSTALLATION
2.1. GENERAL
In the installation procedure, the following actions are distinguished:
- Hardware Installation (different for model 25-A and model 25-S0/model 35;
- Projecting the Supervisor in the ISPBX;
- Supervisor Firmware Installation (see chapter 4. "MANAGEMENT TOOLS".
Note that the installation description is valid for the various types of ISPBXs. The installation
procedures are valid for the model 25 and model 35. The installation procedure for model 25
differs for the installation with analogue interface and S0bus interface. If installed with analogue
interface, the procedures refer to the console as model 25-A. If installed with S0bus interface
the procedures refer to the console as model 25-S 0.
Choose the procedures and steps which are applicable to your system configuration.
2.1.1. Safety Requirements for Power Provision from the System
- Analogue Operator Interfaces of all SOPHO ISPBX systems meet the following
requirements:
- The power provision agrees with the requirements for SETV circuits: EN 60950.
- The power provision from the ISPBX system is protected against short circuit and
overload by means of a glass fuse which is conform the IEC 127 requirements. The
specifications for this fuse are: 3,15 A slow blow, 250 V AC
-S
0bus Operator Interfaces of all ISPBX systems meet the following requirements:
- The output current from the system is limited to 100 mA.
- The voltage from the system is limited to 40 V.
2.2. HARDWARE INSTALLATION OF MODEL 25-A
Model 25 with analogue interface is connected to an analogue operator interface board. In the
table below the analogue interface boards are denoted together with the ISPBX type. Figure
2-1 "Connection between ISPBX and Model 25-A." depicts the interface boards with the cable
layout.

14
Table 2-1 Interface Boards in ISPBX for Model 25-A.
Execute the following steps to install the hardware:
- Connect the console to the appropriate interface board in the ISPBX according to Figure
2-1 "Connection between ISPBX and Model 25-A.". If there are more than one operator
circuits in the ISPBX, check which circuit is to be used. If more information is required on
the interface connections, consult the ISPBX documentation.
- Check that a dummy connector is installed in the S 0 bus interface connector on the
console. If not, install a dummy connector in the S0bus interface. This connector is
required for safety reasons.
A special cable is required to connect the console to either the interface board or to the
connector box. The connector box is required if the cable length of the special cable is not
sufficient. By using a connector box the cable length can be increased to up to 300 meters.
Consult also the Installation Manual or Customer Engineer Manual of your system for more
information on connecting an analogue operator console.

- Cable impedance : 100 ohms at 96 kHz;
- Loop attenuation : < 10 dB/km at 96 kHz;
- Round trip delay : < 1 sec / 100 m;
- Wire diameter : 0,5 mm;
- Bit error rate : 10-7.
Note: If wires are connected together, joints give additional attenuation. Also an Intermediate
Distribution Frame in the cable effects the overall cable characteristics.
More information on the S0bus agreements is found in the CCITT 1.430 recommendation.
At the ISPBX side model 25-S0or model 35 can be connected :
- directly to a DTX-I
- via a PNT1 to a DLC-U, a DLC-C/D or a DOC
- via a PNT1/L to a DLX-U/L
- directly to the PMC-G on board S0bus.
The DOC (Digital Operator Card) is located on a PMC-MC/HR/LU (not on the PMC-G). In
case the PNT1 is used the maximum allowed cable length is increased with 1500m (depending
on the cable characteristics). Note that for the connection between the DLC-C/D/U or the
DOC and the PNT1 only one twisted pair is required. In the figure below the possible
configurations are depicted.
Figure 2-2 Connection Configuration for Model 25-S0or Model 35.

2.3.2. S0Bus Wall Socket Cabling/Wiring
Although the S0bus connector is a 6 pins type, the S0bus wall socket is an eight pin modular
socket. This means that a special cable is required for the connection of the Supervisor to the
wall socket. This cable is delivered together with the console.
The figure below gives an example of the wiring between the DTX-I and the wall socket
together with the Supervisor. In this example circuit 2&3 of the DTX-I are used.
Figure 2-3 Example of S0Bus Cabling with DTX-I.
Figure 2-4 "S0 Bus Wall Socket." depicts an S 0 bus wall socket with the pin assignments. The
power provision is done via pin 3&6 (positive polarity) and pin 4&5 (negative polarity).
The terminating resistor (100 Ohms) which is depicted in Figure 2-3 "Example of S0 Bus
Cabling with DTX-I." and marked with a *, does not necessarily have to be present or installed
in the wall socket. The following configuration rules must be applied for the resistor:
- If the cable length is more than 100 m the terminating resistors are mandatory.
- Only one resistor per wire pair may be installed. Check whether resistors are installed in
the wall socket or (if applied) in a Y splitter.
- If the resistors are installed in a splitter or in a wall socket, the cable length between the
resistor and the console may not exceed 100 m.
Note: A splitter with terminating resistor is enclosed in the packing box of the SV25 and SV35.

Figure 2-4 S0Bus Wall Socket.
In Figure 2-5 "On-site S0 Bus Wiring (with Connector Pin Assignments)." the on-site wiring is
depicted. Again circuits 2&3 are used in this example.
Figure 2-5 On-site S0Bus Wiring (with Connector Pin Assignments).
If your console is model 25, check that the analogue interface connector on the console is
covered with a dummy plate. If not, install the dummy plate. The dummy plate is enclosed in
the packing box of the SV25 and SV35.
2.4. PROJECTING MODEL 25-A IN THE ISPBX
Projecting of model 25-A is done in the same way as all other analogue operator circuits. If
model 25-A replaces an already existing Analogue Operator Console no further projecting is
required.
If model 25-A must be added to an ISPBX, project the interface board in the same way as for
other Analogue Operator Consoles. To do this consult the appropriate system (OM or PE
commands) manuals.
2.5. PROJECTING MODEL 25-S0AND MODEL 35 IN THE ISPBX
Projecting of model 25-S0or model 35 in the ISPBX is done by projecting the DTX-I, the DLC-
C/D/U or the DOC.
