System characteristics:

Flexibility

The FWT 2000i System offers a varietyof modules for the widest possiblerange of transmission tasks. Thanks tothe unlimited equipping options of theframe, virtually all system variantsnecessary for operation can be imple-mented on a customer-specific basis.

Integration in other systems

The modularity of the KS 2000i ChannelUnit is typified by its integration invarious other systems, i.e. its use is notlimited to the FWT 2000i System.

For instance, the channel unit can beintegrated in:

• The PLC-System ESB 2000i;

• The Teleprotection Signaling System SWT 2000 F6;

• Telecontrol systems.

This modularity is possible only becauseall functions have been integrated onone module and a number of differentsupply voltages are possible.

Quick and easy fault location

Fault location is guaranteed to be quickand easy thanks to facilities such as the:

• Local circuit monitors for transmitter and receiver;

• Level monitor for transmitter andreceiver;

• Useful signal level monitor;

• Test code generator;

• Mode selector switch.

Transmitter and receiver as separatemodules

In many cases, users simply require atransmitter in Station A and a receiverin Station B for unidirectional connec-tions. Separate modules that functiononly as a receiver or only as a transmitterare available for this operating method.

Universal for all frequencies andtransmission rates of up to 2400 baud

The basic module of the FWT 2000iSystem is the KS 2000i Channel Unit.It accommodates a complete trans-mitter and receiver assembly.

The KS 2000i Channel Unit is of univer-sal application. All transmission ratesfrom 50 to 2400 baud can be set in allfrequencies within the 30-Hz raster,including in the frequency raster toITU-T.

Transmission in the superimposedfrequency band

The FWT 2000i System permits trans-mission in the frequency range from300 to 7200 Hz.

A second band can thus be used oncable runs along with the normal voiceband from 300 to 3400 Hz. The samechannel assignment is possible in thissuperimposed frequency band as in thebasic frequency band.

Optimization of transmissioncapacity

The transmission capacity of the FWT2000i System can be further increasedby setting up narrow-band channels.

The improved transmission character-istics result in distortion values fornarrow-band channels that are lowerthan the distortion values for broad-bandchannels in older systems, thusachieving optimal transmission quality.

Alternative path switching

For the transmission of important data,transmission paths are frequently dupli-cated. On the send side, the signal isapplied to two paths. On the receiveside, switchover from the main path tothe standby path takes place in theevent of a fault. This function is per-formed by the alternative path switchingmodule (ZWU).

The system’s internal switchover criteriaare the:

• Receive level;

• Signal-to-noise ratio.

Either of these criteria alone or the twotogether can result in switchover.Users can determine the switchoverthreshold within a wide range.In addition to the system’s internalswitchover criteria, switchover can alsobe controlled externally, e.g. by thetelecontrol unit.

The alternative path switching modulepermits the selection of line (LU) orchannel (KU) switchover. Transmissionpath priority is determined by means ofa front connector.

Control frequency transmission formulti-station control systems

The audio-frequency multi-stationcontrol system is a special type of tele-control system. It is used, for example,for changing meter rates and for con-trolling street and traffic lights.

The audio-frequency multi-stationcontrol converter (TRU) converts thecontrol frequency signals for transmit-ting the multi-station control frequency.The signal is output on a VFT transmittervia a V.28 interface. In this way, thecontrol frequency is routed to the cor-responding station using a minimum offrequency space. A VFT receiver routesthe control frequency signal to the TRUreceiver unit, which contains a controlfrequency filter. This filter greatlyreduces the jittering that interfereswith multi-station control. Thus, acontrol frequency of the best possiblequality is supplied to the multi-stationcontrol command unit in the substation.

Data transmission in the voice bandwith SEU 2000i

The SEU 2000i module comprises atransmitter and receiver for transmittinga data channel via a 2-wire or 4-wire linein the voice band from 300 to 3400 Hz.Due to the fact that signal processingis less complex, this module offers aneconomical alternative in cases whereflexibility is limited.

The SEU 2000i module is identical tothe KS 2000i Channel Unit.Since the pin assignment is the same,the SEU 2000i can be installedwherever a KS 2000i can be installed(e.g. adapter module in telecontrolunits).

In contrast to the KS 2000i, only 4 fre-quencies can be set on the SEU 2000i.The first two frequencies are identicalto those of the earlier SEU A,B/STmodules. The second frequency pairmakes it possible to transmit a1200 baud duplex channel via a two-wire cable connection.

The SEU 2000i was designed with aview to possible advantages for users,including economical system manage-ment, transmission security andreliability and short process cycletimes, as well as easy handling.

Compatibility

The FWT 2000i System is fully com-patible with the predecessor systemFWT 2000 and can be operated withother VFT systems.

• The FWT 2000i modules also operatein the module frames of theFWT 2000 System.

• The modules of the old FWT 2000 System also operate in the module frames of the new FWT 2000iSystem.

• The KS 2000i Channel Unit can be installed in any module adapter in which the KS 2000 can be installed.

• The SEU 2000i can be installed in anymodule adapter in which the KS 2000ior KS 2000 can be installed.

• Due to its flexible setting options, theKS 2000i Channel Unit operates in conjunction with all VFT systems.

Optimal security and reliability

Users’ demands for operationalsecurity and reliability are met by thefollowing special features of theFWT 2000i System:

• The effects of temperature and aging are practically eliminated by the use ofdigital signal processors.

• The power supply concept permits secondary voltages of ± 12 V from twopower supply units to be connectedin parallel.

• The power supply units can also be fedwith different primary voltages.

• The receiver unit monitors the level and the signal-to-noise ratio.When transmission ratios worsen,a prealarm is activated.

• When there is no guarantee of data security, the output is applied tocontinuous potential, thus preventingthe system from outputting incorrect data.

• The local circuit to the VFT transmitteris monitored for interruptions. In the event of an interruption, the receiver isset to continuous polarity in order to prevent the output of incorrect data.

• Voltage-carrying modules can beinserted and removed, thus permittingall the other modules to remainin operation.

• The secondary voltage can be suppliedto the alternative path switchingmodule from two power supply units.
