repairs to this product. No installation, adjustment, maintenance or repairs should be performed by
either the operator or the user.
Handling Energized Products
General Safety Practices
Do not touch or tamper with the power supply when the power cord is connected. Line voltages may be
present inside certain products even when the power switch (if installed) is in the OFF position or a fuse is
blown. For DC-powered products, although the voltages levels are usually not hazardous, energy hazards
may still exist.
Before working on equipment connected to power lines or telecommunication lines, remove jewelry or any
other metallic object that may come into contact with energized parts.
Unless otherwise specified, all products are intended to be grounded during normal use. Grounding is
provided by connecting the mains plug to a wall socket with a protective earth terminal. If an earth lug is
provided on the product, it should be connected to the protective earth at all times, by a wire with a
diameter of 18 AWG or wider. Rack-mounted equipment should be mounted only in earthed racks and
cabinets.
Always make the ground connection first and disconnect it last. Do not connect telecommunication cables
to ungrounded equipment. Make sure that all other cables are disconnected before disconnecting the
ground.
Connection of AC Mains
Make sure that the electrical installation complies with local codes.
Always connect the AC plug to a wall socket with a protective ground.
The maximum permissible current capability of the branch distribution circuit that supplies power to the
product is 16A. The circuit breaker in the building installation should have high breaking capacity and must
operate at short-circuit current exceeding 35A.
Always connect the power cord first to the equipment and then to the wall socket. If a power switch is
provided in the equipment, set it to the OFF position. If the power cord cannot be readily disconnected in
case of emergency, make sure that a readily accessible circuit breaker or emergency switch is installed in the
building installation.
In cases when the power distribution system is IT type, the switch must disconnect both poles
simultaneously.
Connection of DC Mains
Unless otherwise specified in the manual, the DC input to the equipment is floating in reference to the ground.
Any single pole can be externally grounded.
Due to the high current capability of DC mains systems, care should be taken when connecting the DC supply
to avoid short-circuits and fire hazards.
DC units should be installed in a restricted access area, i.e. an area where access is authorized only to
qualified service and maintenance personnel.
Make sure that the DC supply is electrically isolated from any AC source and that the installation complies
with the local codes.
The maximum permissible current capability of the branch distribution circuit that supplies power to the
product is 16A. The circuit breaker in the building installation should have high breaking capacity and must
operate at short-circuit current exceeding 35A.
Before connecting the DC supply wires, ensure that power is removed from the DC circuit. Locate the
circuit breaker of the panel board that services the equipment and switch it to the OFF position. When
connecting the DC supply wires, first connect the ground wire to the corresponding terminal, then the
positive pole and last the negative pole. Switch the circuit breaker back to the ON position.
A readily accessible disconnect device that is suitably rated and approved should be incorporated in the
building installation.
If the DC mains are floating, the switch must disconnect both poles simultaneously.
Connection of Data and Telecommunications Cables
Data and telecommunication interfaces are classified according to their safety status.
The following table lists the status of several standard interfaces. If the status of a given port differs from
the standard one, a notice will be given in the manual.

TNV-3 Telecommunication Network Voltage-3:
Ports whose normal operating voltage exceeds the
limits of SELV (usually up to 120 VDC or telephone
ringing voltages), on which overvoltages from
telecommunication networks are possible.
Always connect a given port to a port of the same safety status. If in doubt, seek the assistance of a
qualified safety engineer.
Always make sure that the equipment is grounded before connecting telecommunication cables. Do
not disconnect the ground connection before disconnecting all telecommunications cables.
Some SELV and non-SELV circuits use the same connectors. Use caution when connecting cables.
Extra caution should be exercised during thunderstorms.
When using shielded or coaxial cables, verify that there is a good ground connection at both ends. The
earthing and bonding of the ground connections should comply with the local codes.
The telecommunication wiring in the building may be damaged or present a fire hazard in case of
contact between exposed external wires and the AC power lines. In order to reduce the risk, there are
restrictions on the diameter of wires in the telecom cables, between the equipment and the mating
connectors.
Caution
Attention
To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cords.
Pour réduire les risques s’incendie, utiliser seulement des conducteurs de
télécommunications 26 AWG ou de section supérieure.
Some ports are suitable for connection to intra-building or non-exposed wiring or cabling only. In such
cases, a notice will be given in the installation instructions.
Do not attempt to tamper with any carrier-provided equipment or connection hardware.
Electromagnetic Compatibility (EMC)
The equipment is designed and approved to comply with the electromagnetic regulations of major
regulatory bodies. The following instructions may enhance the performance of the equipment and will
provide better protection against excessive emission and better immunity against disturbances.
A good earth connection is essential. When installing the equipment in a rack, make sure to remove all
traces of paint from the mounting points. Use suitable lock-washers and torque. If an external
grounding lug is provided, connect it to the earth bus using braided wire as short as possible.
The equipment is designed to comply with EMC requirements when connecting it with unshielded
twisted pair (UTP) cables. However, the use of shielded wires is always recommended, especially for
high-rate data. In some cases, when unshielded wires are used, ferrite cores should be installed on
certain cables. In such cases, special instructions are provided in the manual.
Disconnect all wires which are not in permanent use, such as cables used for one-time configuration.
The compliance of the equipment with the regulations for conducted emission on the data lines is
dependent on the cable quality. The emission is tested for UTP with 80 dB longitudinal conversion loss
(LCL).
Unless otherwise specified or described in the manual, TNV-1 and TNV-3 ports provide secondary
protection against surges on the data lines. Primary protectors should be provided in the building
installation.
The equipment is designed to provide adequate protection against electro-static discharge (ESD).
However, it is good working practice to use caution when connecting cables terminated with plastic
connectors (without a grounded metal hood, such as flat cables) to sensitive data lines. Before
connecting such cables, discharge yourself by touching earth ground or wear an ESD preventive wrist
strap.

Internal Jumpers
In order to avoid the possibility of electrical shock, always disconnect the
power cable from mains before opening the SPS-3S.
Warning
The SPS-3S main board has a number of internal jumpers. Refer to Figure 2-2 and
use the following descriptions of the more important jumpers.
INIT - NOR jumper, JP25
The JP25 jumper is used to select the default set of configuration parameters
stored in the unit. The jumper has two positions:
•
NOR – Normal operation. SPS-3S uses the parameters selected by the user
during the last configuration session.
•
INIT – Initialization. Upon turn-on, SPS-3S loads the default configuration
(determined by the factory and common to all the SPS-3S units). To select the
default configuration, refer to the RAD Packet Switching Guide.
The factory setting is NOR.
JP1
JP1 is not used. It is for future applications only.
The JP1 factory setting is NORMAL-NVRAM.
JP21, JP22
JP21 and JP22are not used. It is for future applications only.
The factory setting for JP21 and JP22 is RTS.
JP2
This jumper is used to set the unit when an IR-ETH or U-INT interface is used.
•
IR-ETH
JP2 is shorted to pins 2 and 3 (towards the front panel)
•
U-INT
JP2 is shorted to pins 1 and 2 (towards the back panel)
The factory setting for JP2 is U-INT.
BRG1, BRG2, BRG3, JP4, JP5, JP6
These jumpers are in use when working with the X.21 interface in the DCE mode.
To work the X.21 interface in the DCE mode, the jumper must be connected in
accordance with the interface in use.
For example, if you are using the X.21 interface in DCE mode, JP4 (BRG2) must be
connected to Link 2. To work with Link 1, connect JP5 (BRG1). To work with

Installation and Operation Manual
In order to avoid the possibility of electrical shock, always disconnect the
power cable from wall plug before opening the SPS-3S.
Each interface board can be configured as DCE or DTE by changing the main
jumper. The main jumper consists of multiple jumpers that must be changed
together. Each board is marked DCE DTE. The UI-X21 interface board is shown
in Figure 2-3.
Figure 2-3. UI-232 Interface Board
The interface board determines the physical layer configuration of a SPS-3S link.
When the board is set as DTE, the link must be used with a flat cable to connect to
a terminal. The link receives its clock from outside and the clock parameter must
be configured as external clock.
When the board is set as DCE, the link uses the internal clock, and the clock
parameter must be configured as internal clock (for more information, see the
RAD Packet Switching Guide).
Jumper Setting Procedure
In order to avoid the possibility of electrical shock, always disconnect the
power cable from the wall plug before opening the unit.
Warning
To access the printed circuit board of SPS-3S, loosen screws on the bottom of the
unit and remove the top cover.
Refer to Figure 2-2 or Figure 2-3and identify jumper locations and settings. Change
settings as required.
Replace the SPS-3S cover, gently push it down until it clips into place and fasten
screws.

Installation in 19" Racks
SPS-3S can be installed in 19" racks. Unit height corresponds to 1U (1.75"). The
width of the unit is slightly less than the available mounting width.
An adapter kit provides the hardware necessary for installation of the unit in 19"
racks. The paragraph below provides step-by-step instructions for this procedure.
Disconnect the units from AC power while performing the following
procedures.
Warning
Installation of the Unit
The rack adapter kit for the installation includes two long-arm brackets. The
brackets are fastened by means of screws to the two side walls of the case. The
installation of SPS-3S is shown in Figure 2-4.
To prepare the unit for rack installation, attach the two brackets to the side walls of
the unit. Each bracket is fastened by means of two screws (with flat washers),
which are inserted into the two front holes on the side wall (nuts are already in
place, on the inner side of the wall).
After attaching the brackets, the unit is ready for installation in the 19" rack. Fasten
the brackets to the side rails of the 19" rack by means of four screws (not included
in the kit), two on each side.

Cable Connections
General
SPS-3S has three connectors located on the rear panel that serve the synchronous
links, and an RJ-45 connector located on the front panel for the asynchronous data
channels.
Asynchronous Data Channel Connections
The SPS-3S channel interfaces are configured as data communication equipment
(DCE) interfaces, thereby allowing direct connection, via RS-232 port cables, to
data terminal equipment (DTE). When modems are used to extend the range (tailend circuits), cross-over cables are required. Channel interfaces are asynchronous,
therefore clock signals are neither supported, or required.
The Packet Switching Guide lists pin allocations in SPS-3S data channel connectors,
and provides typical wiring diagrams for straight-through and cross-over cables.
Synchronous Links Connection
Each interface board can be configured as DCE or DTE by changing the main
jumper. The main jumper consists of multiple jumpers that must be changed
together. Each board is marked DCE DTE. The X.25 link connectors type
depends on the SPS-3S interface:
•
V.24:
25-pin D-type, female connector
•
X.21:
25-pin D-type, female connector (via adapter cable)
•
V.35:
25-pin D-type, female connector (via adapter cable)
•
V.36:
25-pin D-type, female connector (via adapter cable)
•
RS-530:
25-pin D-type, female connector
•
IR-ETH:
10BaseT, UTP cable, RJ-45
•
ISDN
S-interface, UTP cable, RJ-45
•
DDS:
8-pin RJ-45, female connector.
Appendix A provides the pin allocations.
Note
The user data cables and the synchronous links cables should be shielded, in order
to comply with FCC rules. The SPS-3S and its data interfaces will work well even if
the cables are not shielded, but some radio interference may occur.
Power Connection
AC power should be supplied to the SPS-3S through the 5 feet (1.5m) power cable
terminated by a standard 3-prong plug. Connect the cable between the AC mains
connector on the SPS-3S rear panel and a standard grounded AC outlet.

Warning
Chapter 2 Installation
BEFORE APPLYING POWER TO THIS UNIT, the protective earth terminals of
this instrument must be connected to the protective ground conductor of the
(mains) power cord. The mains plug should only be inserted in a socket outlet
provided with a protective earth contact. The protective action must not be
negated by use of an extension cord (power cable) without a protective
conductor (grounding).
Make sure that only fuses with the required rated current, as marked on the
SPS-3S rear panel, are used for replacement. The use of repaired fuses and
the short-circuiting of fuse holders must be avoided.
Whenever it is likely that the protection offered by fuses has been impaired,
the instrument must be made inoperative and be secured against any
unintended operation.
Any interruption of the protective (grounding) conductor (inside or outside the
unit) or disconnecting the protective earth terminal can make this unit
dangerous. Intentional interruption is prohibited.
