TEBIT 805 User Guide (R8) TEBIT – Introduction
1 TEBIT - Introduction
Authorized and properly trained personnel only is admitted to carry

DANGER out programming, installation, commissioning, maintenance,
troubleshooting and work of the equipment.
Overview
The Teleprotection and Binary Unit (TEBIT) combines two different possibilities of signal transmission, the
very high reliable teleprotection command transmission and the simple transmission of any binary signals.
Signal processing and transmission are completely separated for both teleprotection and binary command
transmission.
TEBIT contains 4 independent teleprotection command in- and output circuits, which can be assigned
flexible to two teleprotection subunits (SbU1 and SbU2). Up to 4 commands are transmitted simultaneously
through one 64 kbit/s channel.
The teleprotection interface of TEBIT complies with IEC 60834-1 allowing the following protection schemes:
 Permissive tripping (under- / overreaching)

 Intertripping (transfer tripping)
 Blocking / Unblocking
 T-off (normal or inverse)
Transmission-speed, -security and -dependability can be chosen in two steps to optimize the transmission
either for speed or security.
The transmission path of each command is monitored by cyclic loop tests. Failures are reported and may be
indicated with relay contacts.
All events on TEBIT are stored in an event recorder. In order to have the recorded events in a fixed time
relation on both transmitting and receiving side, the stations are time-synchronized. For highest accuracy
TEBIT allows synchronization to the GPS (Global Positioning System).
Additionally TEBIT contains 8 binary in- and outputs, which allow remote transmission of any binary contact
information. Similar to the teleprotection commands these binary commands can be assigned flexible to the
two subunits SbU3, SbU4. 8 binary signals are multiplexed into one 64 kbit/s channel.
This Binary interface is not designed to carry any trip commands. The interface is optimized for fast
transmission and is not protected by an additional communication protocol. Therefore an AIS signal
automatically leads to a binary “1” signal.
The binary signal transmission allows Drop and Insert as well as Point-Multipoint connections on single
contact level.

P1, P2 P2, P3, P4 P4, P5 P1, P3, P5
Due to the drop & insert feature of TEBIT, only one 64 kbit/s channel is required to transmit the 5
teleprotection signals P1 … P5. With speed optimization we get the following propagation delay times T0 :
Signal P1 (A-D) Delay T0 < 8ms (2 intermediate TEBIT)

Signal P2 (A-B) Delay T0 < 5ms (no intermediate TEBIT)
Signal P3 (B-D) Delay T0 < 6.5ms (1 intermediate TEBIT)
Signal P4 (B-C) Delay T0 < 5ms (no intermediate TEBIT)
Signal P5 (C-D) Delay T0 < 5ms (no intermediate TEBIT)
Each intermediate station adds approx. 1.5ms delay with speed optimization and approx. 2.5 ms with
security optimization.
As an alternative, a separate 64 kbit/s channel can be used for the signal P1 that links the terminal stations
A and D. By doing this, the signal will be passed through intermediate stations, reducing the overall
transmission delay for P1 to 5 ms.

Block Diagram / Unit Design TEBIT 805 User Guide (R8)
Design
TEBIT is designed as a standard 6U FOX-U / FOX 515 interface with

single module width. All settings are made software controlled by the
universal configuration software tool (UCST)
The customer interface is located at the front, whereas teleprotection and
binary signals have different connectors. Teleprotection signals are
connected with a shielded cable, with a D-connector on equipment side
and a robust 22-pole terminal block on customer side. The binary signals
are connected with a cable fitted with a 37-pole Sub-D connector on one
and single wires for MDF connection on the other side.
TEBIT comprises the following function blocks:
 Teleprotection I/O interface
 Binary I/O interface
 Auxiliary relays
 Auxiliary power supply
 IRIG-B time synchronization
 Signal processing
 Microprocessor Control
Teleprotection I/O interface
The teleprotection I/O interface is an EMC robust interface comprising 4
independent in- and outputs, which are galvanically isolated against earth
and each other.
The inputs do not need any hardware configuration. They are designed to
handle the complete input voltage range. Every input contains an
electronic circuit with its major part, the ASIC ‘BICA’. ‘BICA’ converts the
input voltage into a pulse width modulated signal (PWM). These PWM
signals are fed via opto-couplers to the signal processing part where they
are evaluated.
The outputs are connected to solid-state relays (Power MOSFET), which
are protected against reversal polarity. In order to protect the output
transistor from over-load, the load current is monitored. In case of a
short-circuit the output is disabled.
Binary I/O interface
The binary interface contains 8 galvanically isolated in- and outputs.
 Note: This Binary interface is not intended to carry any trip commands.
The inputs don’t need any hardware configuration either. As the voltage
range is not extremely high the input circuitry comprises of simple opto-
couplers.
The outputs are realized by low power solid state relays. A protection
against reversal polarity is implemented. The binary outputs can be used
to give out Command Alarms or Acknowledge signal.
Auxiliary relays
TEBIT contains 2 electromechanical relays. Each relay has got a
change–over contact. The relay contact galvanically isolated against

TEBIT 805 User Guide (R8) Block Diagram / Unit Design
earth and to each other. These 2 relays are normally intended to give out
alarm states, but can also be configured to give out trip commands or
binary signals.
Auxiliary power supply
The galvanically isolated auxiliary voltage supply is provided to allow dry
contact to be connected to either the binary or teleprotection interface.
IRIG-B time synchronization
TEBIT contains an Event Recorder. In order to have an accurate time
reference a GPS receiver can be connected to TEBIT. TEBIT supports
the standardized IRIG-B protocol. The evaluation is performed in IRIG-B
decoder, which is part of PLD ‘TEBI’. The IRIG-B input is realized by an
opto-coupler circuitry. This polarized input supports a wide range of input
voltage including TTL.
Signal processing
The processing of teleprotection signals is done in the PLD ’TEBI’, which
is the central part of TEBIT. Due to hardware based signal processing all
4 commands can be processed in parallel by which a rapid and
autonomous processing is secured for each command signal. Not only
the command in- and output evaluation but also the teleprotection- and
output cross-connect is performed in PLD ‘TEBI’.
The binary signal processing is split up between Controller and PLD.
The digital pre-filtering is done in the PLD; the C controls the cross-
connect and output.
Transmission channel assignment and control of UBUS connection
is part of PLD ‘TEBI’ too.
Microprocessor Control
The processor controls all processes within the unit such as
configuration and communication with the central card. Moreover
the processor monitors all events on the card and records them in
an Event Recorder. The data are stored in a non-volatile RAM.

TEBIT 805 User Guide (R8) Operation Fundamentals
4 Operation Fundamentals
Teleprotection
Signal transmission
The teleprotection signal transmission is based on the safety frame
concept (SFC), which ABB uses for many years for fast and extremely
reliable transmission of teleprotection data.
The safety frame consists of 32 bits whereas 8 bits are used for
synchronization. The frame evaluation is bit-oriented and thus completely
independent on the byte synchronization of the G.704 2 Mbit/s data
frame. The frame structure is extremely secure. Its concept avoids any
shifting of data or wrong synchronization even during erroneous
transmission. The concept of 8 distributed synchronization bits together
with some checks on data integrity allows to check immediately each
frame for correct transmission on the receiver side. Furthermore, the
frame contains 8 bits for frame addressing, 15 bits for teleprotection
command coding and 1 bit to transfer service data. The frame duration is
0.5 ms. Following figure shows the bit allocation.

0 1 1 1 1 0 0 0 S
Synchronization bit
Frame address
Code word containing the teleprotection commands
S Service bit
Addressing
In order to recognize and in this way to prevent a false routing of
teleprotection data in digital transmission network each transmission
frame contains 8 addressing bits. These 8 bits allow an address range
from 1…254. (00, FF is not allowed). The address is checked each
frame. If there is a false address the frame is discarded. After detection of
an address failure an alarm is raised and the command outputs are
blocked.
Command coding
For the transmission of command and loop test information a special 15-
bit block code with a hamming distance of d=7 is used. The block code
principle allows a simultaneous transmission of teleprotection- and loop
test commands. During the transmission of the loop test command the
hamming distance is reduced to d=6 for that individual transmission
frame.

Operation Fundamentals TEBIT 805 User Guide (R8)
Service bit
The service bit provides a serial data channel with a transmission
capacity of max. 2000 bit/s. This serial data channel is used by the
Controller to transmit reference time and remote alarm information.
Input signal processing
The teleprotection inputs are able to work within the complete possible
input voltage range from 24…250 VDC without any hardware stripping.
This is possible by converting the input voltage in a pulse width
modulated (PWM) signal. The duty-cycle of the PWM is measured, which
gives an indication for the presence of a command signal. As the duty-
cycle decreases when the voltage increases the power dissipation at the
inputs is relative low even with input voltages at the upper voltage range.
In order to ensure a proper conducting of the output contacts of the
connected protection relay, the input current sinks a higher current during
a short time of the rising edge of the input command.
A pre-filtering is implemented in order to prevent short spikes to be
transmitted as teleprotection commands. Depending on the operation
mode the TX command is set active only after multiple receipt of a PWM
signal corresponding to a signal level high as the input threshold.
Moreover the input signal duration can be monitored. Command duration
of > 5s will then initiate an alarm condition.
Operating modes
In order to fulfill the requirements for different teleprotection schemes,

transmission can be optimized either for speed or security. Propagation
delay, dependability and security are influenced by these settings. For
details please refer to the technical data.
With speed optimization an output command is activated after evaluation
of 2 frames, whereas with security optimization 4 frames have to be
identical before an output command is activated. Furthermore there is a
difference between both operation modes also on TX side. With speed
optimization an active TX command is sent after evaluation of 2 PWM
periods of ASIC ‘BICA’ and with security optimization a TX command is
activated only after 4 PWM periods. A BICA period may vary between 0.5
and 1.0 ms depending on the component: typical is 0.7 ms.
Networking facilities and
Command Cross Connect
The teleprotection command cross connect works on single-command
level and supports a high degree of flexibility regarding different operation
possibilities, which are:
 Point-Point set-up:
Fig. 3.6: Point-to-Point set-up, e.g. for 4 commands
 Point-Point set-up into two directions:

Fig. 3.7: Point-to-Point set-up into two directions, e.g. for 4 commands
 Drop-off and Insert:

Fig. 3.8: Point-to-Point set-up into two directions

 T-Operation:
Fig. 3.9: Point-to-Point set-up into two directions
TX command acknowledge
TEBIT has the possibility to acknowledge an incoming trip. The signal
“Command Ack” is an exact copy of the command signal and can be
connected to an output circuit according to the possibilities of the output
cross connect matrix.
Channel monitoring and 1+1 path protection
The received data are monitored continuously for block code errors.
Depending on the operation mode a data bloc contains either 2 (speed
optimization) or 4 (security optimization) frames. A block is faulty if at
least one incorrect frame as been detected. Block errors are counted. A
block error rate (BLER) of > 10-2 generates a non-urgent alarm.
A very fast 1+1 protection switching has been implemented to meet the
requirements for teleprotection. It switches if there are more than 50%
faulty receive frames during a time period of 4 ms. 1+1 switching for
binary signals is different and much slower!
Loop tests and propagation delay measurement
The correct operation of the complete teleprotection command channel is

checked periodically. For that purpose each terminal station sends a test
pattern, which is acknowledged by the partner station. This Loop test is
repeated automatically every minute. The loop tests are carried
independently for each of the 4 commands.
Together with the loop test the propagation delay between the two
terminal TEBIT stations is measured and monitored. This measurement
is based on equal propagation delay in both directions. Delay coming
from command in- and output circuitry is not measured, but typical values

are included in the delay time indication. The time stability of the
transmission path is monitored. Deviations of more than 0,5 ms between
two measurements are recorded in the event recorder.
Trip Counter
For every command there is a volatile trip counter that counts up to 99

trip commands. The counters can be monitored and set to zero by the
user interface UCST. The exceeding of 99 trips causes an event-recorder
entry (i.e. when the trip counter changes from 99 to 01).

Event Recorder
General
TEBIT provides an internal non-volatile event recorder for both card
specific and teleprotection events. Dependent on the available time
reference, events are recorded with a precision of a few milliseconds,
thus providing an accurate log of all trip commands, system failures etc.
The event recorder can be viewed with configurable filters via UCST.
Time reference
In order to evaluate recorded events, both transmitting and receiving
station have to be in a fixed time relationship. For this purpose TEBIT
contains certain facilities to synchronize the time reference of the event
recorders. Time can be taken from the following sources:
 Global Positioning System (GPS)
 Remote TEBIT on SbU1
 Remote TEBIT on SbU2
 Network element time
 None (internal micro-controller clock)
The following examples show three typical time synchronization set-ups.
 Time-Synchronization to GPS in all stations:

The highest accuracy is achieved if all TEBITs in the network are
synchronized directly to GPS. In this case the propagation delay between
the stations does not influence the accuracy. The time is exactly the
same on all TEBITs.

 Time-Synchronization to GPS only in the central station

All TEBIT event recorders have GPS as there time base, but only the
central station is in exact time synchronization to GPS. The subsequent
stations have a time deviation, which corresponds to the propagation
delay of the communication channel.

 Time-Synchronization to Network Element Time

If there is no GPS receiver available all TEBITs are synchronized to one
time master station. In this case all the TEBITs are synchronous to one
master clock, but also as for the above example there is a time difference
between the individual TEBITs. This time difference is equals to
propagation delay of the communication channel.

Binary Signals
General
In addition to the teleprotection signal transmission, binary signals such
status indication or tax impulses can be transmitted through the binary
interface. The binary signal transmission is a second, separate function.
It is completely decoupled from the teleprotection command transmission
using both separate data interfaces and separate transmission subunits.
The requirements for secure transmission are not as high as for
teleprotection signaling; nevertheless a build-in signal filtering ensures a
reliable communication even under disturbed conditions i.e. bit errors in
the communication channel.
Cross Connect Possibilities
The binary signal cross connect offers the following possibilities on
single–signal level
 Point-to Point
 Drop & Insert
 “Wired-Or” Omnibus
Path Protection
For binary signal transmission reversible and non-reversible 1+1
switching are based on the FOX-U / FOX 515 standard 1+1 function
using CAS. The switchover time is about 100 ms.
Data Transmission
The binary interface can be used to transmit slow data such as tax pulses
at a rate up to 20 baud.
Interconnection with FOX20/FOX6Plus Binary Interface N3BH
As both interface units use the same data structure, a direct co-operation
between FOX20/FOX 6Plus Binary Interface N3BH on one side and
TEBIT Binary Interface on the other side is possible.

possibilities to established teleprotection network solutions. Besides
simple point-to-point configurations, many sophisticated network
solutions, including T-Operation as well as Drop & Insert, are possible.
The user can choose between different ‘Pre-configurations’ or set up the
connections individually by means of the buttons within the cross
connects matrix itself.
In addition to the cross-connect, Multiple Output connection can be
configured in this mask too.
Fig. 3.18:

 Pre-configuration
From a drop down list several predefined applications can be chosen,
which are
Point-to-Point with 4 commands in one direction
T- Operation with 1, 2, 3 or 4 commands
Inverse T-Operation with 1, 2, 3 or 4 commands
 Individual configuration
Individual configurations are possible just by clicking on either the
connection points or the blocks at the output line. The blocks at the
output line can have three different states:
- through connection [ I ]
- OR connection [ 1 ]
- AND connection [ & ]
‘OR’ resp. ‘AND’ connections are necessary if there are more than one
signal input per output line.

Note: Not all connections are possible. If so, the ‘OK’ button is grayed indicating that the chosen
connections are not allowed.
 Multiple Output
If not all outputs are occupied these outputs can be used for other signals
to establish multiple outputs. Please refer to Fig. 3.23 for an example
Application examples of Tele-

protection Networking Solutions
Examples of typical Teleprotection Applications:
 Point-to-Point transmission of 4 command in one direction

Pre-configuration according to fig. 3.18

 Point-to-Point set-up with 2 commands into two directions

Fig. 3.19:
 T-operation (T-off) with 1 command

Fig. 3.20:

 Inverse T-off with 2 commands

Fig. 3.21:
 Drop Off and Insert with Cmd 1, Cmd2; Cmd 3, Cmd4 in Transit
Fig. 3.22:

 Simple Point-to-Point connection with 1 command given out to 4 outputs (Multiple Output)
Fig. 3.23:

Output Configuration ‘Unit Configuration’ / ‘Parameters...’ / ‘Board’ / 'Output Cross

Connect'
The output cross connect matrix assigns the output signals
coming from ‘Binary Cross Connect’ and ‘Teleprotection Cross
Connect’ to output circuits. In addition to the binary and
teleprotection signals the ‘Command Alarm Signals’ and the
‘Command Acknowledge Signal’ can be assigned to output
circuits too.
Fig. 3.24:
 TPO (Teleprotection Output)

The TPOs are the solid-state power outputs capable to control line
protection terminals. They are normally used for teleprotection
application, but can also be used for Binary or Acknowledge Signals, if
there is a demand for more power.
 BOUT(Binary Output)
The BOUTs are low voltage and low power sold-state outputs and
intended to give out other control signals than teleprotection commands,
including Alarm and Acknowledge Signals.
 Aux (Auxiliary Relay)
The AUX outputs are robust electromechanical relays with one
changeover contact. They can be used for any of TEBIT’s signals, but

they are especially intended to be used as Alarm outputs. Up to 4

Command Alarm Signals can be ‘Wired-Or’ connected to 1 Auxiliary
Relay output building a Common Alarm output.
 Note: In order to have a Wired-Or alarm connection it is necessary to

configure the ‘Alarm State’ to ‘Output Open’.

Automatic Loop Test Commands: Automatic Loop Test Settings'
In order to ensure correct operation, all command paths can be
monitored automatically. A loop test command is sent to the
partner station every minute, answered with an acknowledge
signal.
Fig. 3.25:
 Automatic Loop Test

Per default the loop test is enabled. Normally the automatic loop test
stays enabled except when a command is not connected to a partner
station.
Time Reference ‘Unit Configuration’ / ‘Parameters...’ / ‘Board’ / ‘Time Reference’

The ‘Time Reference’ defines the source to synchronize the real
time clock of the Event Recorder. To follow the time sequence of
events on both transmit and receive side it is necessary that both
side are synchronized to the same time reference.
Fig. 3.26:

 Source
There are 4 different sources that can be used to synchronize the TEBIT
event recorder time. To choose a source, click on the source and give a
priority to that source by selecting the priority from the drop down list
‘Priority’.
If a source shall be disabled priority ‘None’ is to be selected.
 Note: It is recommended to use a correct time reference (preferably GPS), so

that all events could be merged properly in the database of other
management systems.
 Note: After each power interruption the network element date and time should
be re-entered externally (UCST/FOXMAN-UN) if the event recorder
uses this time reference.
 Note: If all sources are configured with priority ‘None’ TEBIT’s clock is free
running controlled from the micro controller quartz.
Teleprotection Transmission ‘Unit Configuration’ / ‘Parameters...’ / ‘Traffic’ / ‘Teleprotection

Parameters (SbU1, SbU2) Command Parameters’
The transmission parameters define the channel addressing and
teleprotection operation modes i.e. transmission optimized ‘For
Speed’ or ‘For Security’
 Note: Transmission parameters, i.e. Addressing and Transmission

Optimization, are applied to the complete bundle of 4 teleprotection
commands.
Fig. 3.27:
 RX, TX Address
To prevent wrong tripping due to routing failures in the
telecommunication network, an 8 bit address signal is implemented to the
teleprotection signal. Both TX address of the transmitting unit and RX
address of the receiving unit must correspond otherwise the channel is
blocked and an alarm initiated.
 Note: RX and TX should not have the same address in order to recognize
loops in the transmission network. Be sure that your address is unique
in the network.

To choose the address either scroll the drop down list or type it directly
into the field RX- or TX Address. The allowed address range is from
1…254
 Optimize Transmission
This parameter is set according to the teleprotection scheme
- Permissive tripping (under- / overreaching)  ‘For Speed’
- Inter-tripping (direct transfer tripping)  ‘For Security’
- Blocking / Unblocking  ‘For Speed’
Path Protection Operation ‘Unit Configuration’ / ‘Parameters...’ / ‘Traffic’ / ‘Mode’

Mode SbUs 1-4
TEBIT supports path protection facilities. From a drop down list,
one of the 3 operation modes can be chosen.
Fig. 3.28:
 Normal
No 1+1 path protection
 1+1
1+1 path protection with Default and Reserve time slot. Both
transmission paths are entitled on the same rights, i.e. a switch-over to
the reserve path will not be change back to default path after recovery.
 1 + 1 Reversible
1+1 path protection with Default and Reserve time slot. The Default time
slot is the main transmission path, i.e. a switchover to the reserve path
will switch back to default as soon it is available again.

Event Recorder ‘Unit Configuration’ / ‘Status/Maintenance…’ / ‘Board’ / ‘Event

Recorder
TEBIT stores in a non-volatile RAM two different categories of
events: the Teleprotection Command and the System Events.
These two categories are stored in two different memory sections
and are presented under UCST with two different lists. Division
into two categories results in separate event recorders. This
prevents an overwriting of the very important Teleprotection
Command Events by a toggling System Event (alarm). The
defined events are manifold. Later on a summary of all events can
be found. Different types of filters help with interpretation of the
event lists.

Note: It is possible to export the event list into Microsoft Excel the following
way.
Select the commands to be copied. Then press ‘Ctrl’, ‘C’ to copy the
data into the clipboard. Open an Excel sheet and ‘paste’ the event list
into that sheet.
