PLC – always up-to-date
PowerLink – the versatile solution
PowerLink uses the high-voltage line between trans-
former substations as a communication path for
data, protection signals and voice. This technology,
which has been tried and tested over decades and
adapted to the latest standards, has two main
application areas:
as a communications link between substations■
where a fiber-optic connection does not exist
or would not be economically viable, and
as a backup system for transmitting protection■
signals parallel to an installed fiber-optic link.
A basic distinction is made between analog (aPLC)
and digital (dPLC) systems. Newer digital systems
allow more efficient use of the frequency band,
whereas traditional analog PLC systems offer advan-
tages in cases where transmission conditions areworse (low signal / noise ratio, for example). With
PowerLink, both operating modes are open to you.
You can even combine aPLC and dPLC services in a
single communications network.
PowerLink – developed for thechallenges of the future
PowerLink has numerous outstanding features and
functional units, many of them are patented. The
real hallmark of the system, however, is its openness
and flexibility, which offers you a host of technical
options for the best operation of your communica-
tion networks. You can use PowerLink for the trans-
mission of
Protection signals■
Telecontrol signals■
Voice■
Fax■
Data■
TCP / IP communications■
For this purpose, PowerLink has analog and all cur-
rent digital interfaces. Because these can be com-bined flexibly, you can protect investments you have
already made, and continue to use the older analog
terminals while you gradually switch over to the new
communication technologies. At the same time,
with PowerLink you already have all the possibilities
of TCP / IP communication at your disposal, which is
increasingly emerging as the standard in the power
supply area as well.
A few years ago, it was looking as if digital fiber-optic networks wouldreplace the traditional PLC (power line carrier) systems at power supplyutilities. As it turns out, however, PLC is still an indispensable communi-cations alternative for numerous applications and will remain so in thefuture: This technology ensures extremely high standards of communi-cation in network protection, and can easily be integrated into a widerange of communication networks, as in the case of the SiemensPowerLink PLC system.
Perfect matching to modern communication environments, and built-intechnical potential for the requirements of the future, make PLC systemsmore attractive today than ever before.

PowerLink –highlights in the package
Flexibility for your success
Versatility is one of the great strengths of the PowerLink system.
PowerLink can be matched flexibly to your infrastructure.
Variable transmission power
You can, for example, set the system power via the system software in two
ranges (20 to 50 W or 40 to 100 W) according to the exact requirements
of the transmission route. As far as the transmission itself is concerned,
PowerLink operates with variable data rates and bandwidths in the frequency
band between 24 and 1000 kHz, making it easy to comply with specific
frequency requirements of customers.
Optimum matching to transmission conditions
PowerLink matches the data rate to changes in ambient conditions. This
guarantees optimum transmission power in the network at all times. Due
to PowerLink’s integral prioritization function, which can be configured for
each channel, routing of the most important channels is assured even in
bad weather conditions.
Multi-service devicePowerLink offers the necessary flexibility for transmitting every service the
customer might want in the available band. All services can be combined
in any way within the available bandwidth / bit rate framework.
As a power system operator, your emphasis is onsystem performance. Thanks to a comprehensiveservice portfolio, PowerLink can help you optimizecommunications in your system, utilize band-width efficiently, and permanently improve thereliability of your network operations. The mostimportant aspect of PowerLink is flexibility,always offering you the best possible transmission
performance under all operating conditions.

Automatic crosstalk canceller (AXC)
PowerLink can be operated with or without space
between the transmission and reception bands.
Band to band operation usually requires manual
adjustment to minimize the influence of the trans-
mitter on the receiver. AXC automates this adjust-
ment process, thereby optimizing the transmission
quality. Developed and patented by Siemens, AXC
automatically subtracts the interfering transmission
signals from reception signals (RX-TX). With chang-
ing characteristics of the transmission channel, the
quick adaptation of the AXC ensures optimum trans-
mission quality at all times, without time-consuming
manual adjustment.
Transmission capacity up to 256 kbit / s
PowerLink offers a transmission capacity of
256 kbit / s, and an integrated TCP / IP interface is
available. This means that many different types of
IP terminals can use the power line communications
network effectively.
Maximum efficiency: the integrated,versatile multiplexer (vMUX)
A large number of conventional communication interfaces today
(e.g. a / b telephone, V.24, X.21, etc.) and in the foreseeable
future must be operated in a switching station. For this purpose,
PowerLink uses an integrated versatile multiplexer that bundles
these communication forms together and transmits them by
PLC. The vMUX is a statistical multiplexer with priority control.
Asynchronous data channels can be transmitted in “guaranteed”
or “best effort” modes, to guarantee optimum utilization of
available transmission capacity. The priority control ensures
reliable transmission of the most important asynchronous and
synchronous data channels and voice channels even under poor
transmission conditions. Naturally the vMUX is integrated in the
management system of PowerLink, and is perfectly equipped
for the power line communication requirements of the future
with extended options for transmitting digital voice and data
signals.

Voice compression – less is more
Voice compression is indispensable for the efficient utilization
of networks. Naturally, quality must not suffer, which is why
PowerLink offers comprehensive options for adapting the data
rate to individual requirements. PowerLink offers different com-
pression stages between 5.3 and 8 kbit / s. To prevent any im-
pairment of voice quality, the compressed voice band is routed
transparently to PowerLink stations connected in line, without
any further compression or decompression.
Protection signal transmission systemSWT 3000
A maximum of two independent SWT 3000 systems can be
integrated into each PowerLink. This means that no connection
components are needed. SWT 3000 systems are also fully inte-
grated into the user interface of the PowerLink administration
tool.
One management systemfor all applications
PowerLink not only simplifies your communications, but also
makes communications cost-efficient. The PowerSys software
administers all integrated applications of PowerLink under a stan-
dard user interface. This ensures higher operating security while
cutting training times and costs to the minimum.

PowerLink for data transmission
LAN connection
PowerLink permits establishing a LAN connection
between substations in the high-voltage network.
As well as connecting routers via the X.21 interface,
PowerLink also provides an integrated Ethernet inter-
face. This allows IP-enabled data terminal equipment
to be connected directly at low cost.
Transparent analog data transfer
When PowerLink is used in analog mode, a maximum
of four conventional asynchronous data channels up
to 2400 bit / s can be transmitted transparently bymeans of FSK modulation.
The versatile multiplexer integrated in PowerLink
provides the following functions:
Asynchronous data transmission
Up to eight data terminal equipments can be con-
nected to the PowerLink via the RS232 interface.
These asynchronous data channels can be transmit-
ted in the “guaranteed” or “best effort” modes, and
thus guarantee optimum utilization of the available
transmission capacity.
Synchronous data transmissionPowerLink provides 2 X.21 or 1 G703.1 interfaces
for the data link between plesiochronous (PDH) or
synchronous (SDH) transmission networks.

PowerLink for telephone networks
If you want to set up a telephone network using
PLC units, PowerLink is the reliable way to do this by
simply using your existing TC systems and telephones.
PowerLink is designed for the connection of all
different kinds of telephone systems or for individual
telephones (from analog to IP).
The graphics above provide an overview.
The compressed voice band is routed transparently
with no additional compression or decompression,
so that the voice quality at PowerLink stations con-
nected in between is not impaired. This StationLink
functionality for voice channels is shown in the
following graphic.

The protection signal transmission system SWT 3000can be operated as an integrated system (max. 2
systems) or adapted with PowerLink. Every
SWT 3000 system can transmit up to four protection
commands. Above graphic shows an overview of the
various connection options.
The SWT 3000 system offers you a unique
and varied range of operating options:
Single-purpose mode:■
In this operating mode, the PowerLink transmis-
sion channel is used exclusively for transmitting
protection signals. Maximum transmission ranges
with greatest reliability in the case of pulse noiseand the minimum signal propagation delay are
attained in this mode. A 2-kHz-variant allows the
best possible utilization of frequency space in the
4-kHz band.
PowerLink for protection signal transmission
Multi-purpose mode:■
In this mode voice and data are transmitted
parallel to protection signals.
Alternate multi-purpose mode:■
In this mode, the entire transmission capacity is
used for voice and data as long as it is not needed
for protection purposes. The PowerLink pilot tone
is used as the guard tone in this mode. If a protec-
tion command needs to be transmitted, voice
transmission is interrupted for the duration of
transmission of the protection command. Data
transmission may also be interrupted if the rele-
vant parameter is set.
