3 Transfer Switch
The FSA-PLUS Switcher is designed as a relay-based reversing switch with the
switch function of a change-over contact. With each switching action, all relays will
be switchover together. The max. switching capacity amounts to 100 x 200 copper
pairs. The reversing switch consists of up to five identical groups of components
(Moving Card MOC). Each one of these groups of components switches 20 copper pairs over to 40 copper pairs. The FSA-PLUS Switcher can be equipped with
a random number of MOCs, up to the maximum number. Retroactive fitting or
stripping down by adding or removing MOCs is also possible.
Failures of the power supply do not alter the interconnection state (due to the
bistable relay used!).

4 Applications of the FSA-PLUS Switcher
The FSA -PLUS Switcher can be used both for the switching of one device or system over to another device or system (single mode) and for the switching of a
transmission path over to another transmission path (double mode).
4.1 Application in Double Mode
The FSA-PLUS Switcher can be used in double mode for critical connections
which do not permit interruptions in the event of disturbances on the line level
(e.g. connections to banks, air traffic control, hospitals, etc.).
In double mode, two FSA-PLUS Switchers form a system which, by means of
variable reverse switching criteria, can switch from one transmission path over to
another transmission path. In each switch-over, both FSA-PLUS Switchers are always jointly switched over.
The interaction of the two FSA-PLUS Switchers is carried out by means of a permanent modem connection which enables a distance range of up to 10km. The
modem interface required for this is integrated in the FSA-PLUS Switcher.
The complete signalling of both FSA-PLUS Switcher for switch status and possible
alarms is carried out on the central FSA-PLUS Switcher. The external
FSA-PLUS Switcher limits the signalling to the display of its own switch status as
well as its own alarms.

The reverse switching criterion for the FSA-PLUS Switcher can be selected from
among the following possibilities:
Automatic Reversing
In the case of automatic reversing, the line quality of a copper pair is applied as
reverse switching criterion and this is monitored by means of the external
FSA-PLUS Switcher. At the same time, the line is tested for disturbance and a
minimum insulating resistance of wire to wire and wire to earth. After falling
short of specific limiting values, it is automatically switched from the main path
(SIDE1) over to the reserve path (SIDE2) and a special alarm is set to on.
The switching from the reserve path over to the main path is only possible after
a selectively targeted manual reset.

Manual Reverse Switching
Manual reverse switching can only be carried out via the central FSA-PLUS
Switcher. The criterion for reverse switching is determined (according to the
configuration) either by a local switch on the Switcher or by a remote switch.
The distance of the remote switch can run to several hundred metres.

4.2 Application in Single Mode
In single mode, an FSA-PLUS Switcher forms a reverse switching system which
switchover, by means of variable reverse switching criteria, a device A from a device B over to a device C (e.g. subscriber‘s extension stations, etc.).
The criterion for reverse switching for the FSA-PLUS Switcher can be selected
from among the following possibilities:
Manual external reverse switching
Manual external reverse switching is carried out by means of an external
switch, which can be situated at a distance of up to several hundred metres
away.
Manual local reverse switching
Manual local reverse switching is carried out by means of a switch positioned in
the device.

5 Monitoring and Alarms
The FSA-PLUS Switcher provides extensive options for monitoring as well as the
alarms resulting from this, independent of the configuration.
5.1 Monitoring and Alarms in Double Mode
In double mode, the monitoring and signalling of alarms for the central and external FSA-PLUS Switcher is different, since only the central FSA-PLUS Switcher
receives all the information from the complete system (both FSA-PLUS Switchers). The signalling in the case of the external FSA-PLUS Switcher is limited to its
own status and its own alarms.
5.1.1 Monitoring and Signalling of FSA-PLUS Switcher (Central or External
FSA-PLUS Switcher)
Signalling of switch status
Signalling of operating conditions (auto / manual operation)
Monitoring of all moving cards by means of cyclic write / read operations and
alarm in the event of failure
Recognition of the number of moving cards
Comparison of the number of moving cards (double mode only)
Alarm in the event of failure of an internal voltage
Alarm in the event of failure of the primary supply voltage (DC version only)
Monitoring of the modem connection
Alarm in the event of failure of the modem connection
Monitoring and signalling of the interface for the measurement of the line. In the
case of operation with automatic reverse switching, there is an alarm in addition
to the signalling.
5.1.2 Additional Monitoring and Signalling of the Central FSA-PLUS
Switcher
The central FSA-PLUS Switcher monitors the whole system, i.e. it monitors both
FSA-PLUS Switchers according to the criteria cited in section 5.1.1.
In addition, there is a specifically targeted alarm with details of the alarm as well
as the alarm source which is effected by the central FSA-PLUS Switcher.
In the event of failure of the primary supply voltage (DC version only) or an operating voltage of the external FSA-PLUS Switcher, this failure leads to a specifically
targeted urgent alarm in the FSA-PLUS Switcher.

6 Interfaces
6.1 Power Supply
The FSA-PLUS Switcher is available in an AC version (Alternating Current) and a
DC version (Direct Current).
The power supply of the AC version is designed in such a way that 115 V / 60 Hz
as well as 230 V / 50 Hz can be used for the primary supply. The adjustment of
the power supply to the primary supply voltage occurs automatically.
The power supply of the DC version satisfies the requirements of the European
standard EN ETS 300 132-2 with a possible range of input voltage of
40.5V - 72V DC. The adjustment of the power supply to the primary supply voltage
occurs automatically.
Permitted range of the input voltage
(AC version):
85 - 264 VAC (50 Hz - 60 Hz)
Permitted range of the input voltage
(DC version):
40.5 - 72 VDC in accordance with
ETS 300 132-2
In the case of reverse poling of the interface for the power supply on the FCU
(control card) there is no possibility of normal operation. Reverse poling is nondestructive.

6.2 Modem Interface
The accommodation of two FSA-PLUS Switchers is carried out by means of a
permanent modem connection. This connection is a necessary condition for the
operation of the device. A breakdown in the modem connection causes a specifically targeted alarm to be set off. In this case a reverse switching of the FSAPLUS Switcher is not possible.
Transmission rate 1200 baud/s, half duplex FSK Modem in accordance with
ITU-T V.23

Monitoring of the communication: start bit; stop bit; check total, time out moni-
toring
Satisfies the requirements of ETSI TBR 15 (Jan. 97) and the Dutch regula-
tion T14-01
Control of the communication is carried out by means of the polling principle. The
external FSA-PLUS Switcher is the master with regard to communication.
With every polling cycle, the external FSA-PLUS Switcher informs the central
FSA-PLUS Switcher of the switch status and the alarm status.
The required connection and the monitoring of the switching operation is carried
out by the central FSA-PLUS Switcher.

6.3 Interface for Line Measurements (Double Mode only) or for an External
Switch (Double Mode or Single Mode)
Interfaces for line measurements (double mode only)
The interfaces for line measurements are monitored by an in-circuit copper pair for
a specified minimum insulation resistance (a-wire to b-wire and a-wire or b-wire to
earth) and for a possible opening of the circuit.
Two interfaces are required in order to perform this measurement which is carried
out by an FSA-PLUS Switcher continuously. One interface forms the source with
the appropriate evaluation and the other interface forms a necessary terminal
(see picture2, Chapter 4.1).
The guaranteed values are as follows:
Threshold value for the insulation,
measured a-wire to b-wire and a-wire or
b-wire to earth
Guaranteed values over the whole
specified temperature range
Minimum possible insulation value,
which still does not trigger any alarm
(Lower values must have triggered off
an alarm)
R
Insulation_min
> 1.5 M
Notice: The max. permitted loop resistance

7 Considerations for Use
7.1 Operation and Connecting Plans for the Control Card (FCU)
7.1.1 Path Switching (Double Mode)
With path switching, all the cables are switched together from one bunch of trunks
over to another bunch of trunks. Two FSA-PLUS Switchers are required to perform this reverse switching and these must be installed on each end of the bunch
of trunks. The accommodation of the FSA-PLUS Switcher is carried out by means
of a permanent modem connection.
In the case of automatic reverse switching, a copper pair is applied as the switch
criterion, on which the insulation and the loop resistance are monitored. In the
event of falling short of the defined thresholds (see Page 15) it is automatically
switched from the main path (SIDE1) over to the reserve path (SIDE2).
In double mode, after a connection of the central FSA-PLUS Switcher, a comparison is carried out of the number of recognised moving cards of the two FSA-PLUS
Switcher. In the event of unequal numbers of recognised moving cards, this gives
rise to an alarm and signalling (flashing of LED 3,4,8 or 9). A switch operation is
not possible then.
An automatic switching over to SIDE2 is a once-through operation, independent of
the monitored line data. This switch behaviour will prevent any multiple switching
over from taking place. In addition, it is therefore possible to carry out the switch
back from SIDE2 to SIDE1 to a self-defined time.
In the event that the FSA-PLUS Switcher has automatically switched to SIDE2
and a failure of the distribution voltage or the operating voltage +15V subsequently occurs, this switch status is filed in an internal memory and after restoration of the voltage is used once again as switch status. An undesired switch back
on SIDE1 is therefore prevented.
For a direct switch back onto SIDE1 involves two possibilities. The first possibility
is an application of key S3 (see Page 20) of the external FSA-PLUS Switcher.
When the key is pressed, the LED 4 lights up in acknowledgement. This LED, in
the case of the external FSA-PLUS Switcher, has no other function.

The second possibility is a reversed configuration of the central FSA-PLUS
Switcher in manual mode with the subsequent reversed configuration once again
in automatic mode. In this case, the internal memory is erased. The system there-

Technical Manual

Page 18
fore sets itself automatically at normal status SIDE1 (assuming that the lines are
perfect).
The installation of the lines required for automatic reverse switching should be carried out in accordance with the following installation plan.
The main path (path in the event of perfect operation) is installed on SIDE1.
The reserve path (reserve path) is installed on SIDE2.
The modem connection must be installed with the bunch of trunks from SIDE2
in order to guarantee the communication even in the event of damage to the
cable of the main path.
The monitoring of the cable in the main path must be carried out by means of
the external FSA-PLUS Switcher. In the event of a failure of the lines in the reserve path (SIDE2), it is then possible to determine whether the failure is
caused by the modem connection or the lines.

7.4 Settings and Configurations
7.4.1 Addressing the Moving card (MOC)
Each moving card (MOC) of the FSA-PLUS Switcher must be addressed oncethrough before the start of operation. With this coordination, each MOC will allocate a unique fixed address which enables a specifically targeted triggering and
signalling. Addressing is carried out on the10-pin connecting block and a plug-in
bridge. The configuration of the MOC will differ in MOC1 .... MOC5. MOC1 is the
lowest and MOC5 the highest placed moving card in the Switcher. The names
MOC1..MOC5 are imprinted on the respective pins of the connecting blocks and
are easily visible.
An address of the MOC must never be assigned more than once. This leads to a
malfunction in the FSA-PLUS Switcher. A defined switching of the FSA-PLUS
Switcher is then no longer guaranteed.
The addressed moving cards are tested and indicated in the switch-on process
(see Chapter 7.5.1)
In double mode, following the connection of the central FSA-PLUS Switcher, a
comparison is made of the number of recognised moving cards of both FSA-PLUS
Switcher. In the event of unequal numbers of recognised moving cards, an alarm
is activated.

7.5 Signalling
7.5.1 Signalling during the Switch-On Process
After the FSA-PLUS Switcher has been switched on, a test routine is carried out
with the following signalling, independent of the configuration which has been set:
During the first 3 seconds, all the LEDs light up for a LED test (LED Test)
During the following 3 seconds, all perfect recognised moving cards (MOC) are
displayed. Each MOC is assigned to a LED as follows:
MOC 1
ON
OFF
1
4
MOC 2
MOC 3
MOC 4
MOC 5
Picture 11: Front view of the function control unit (FCU)
The status of ”no MOC recognised” leads to a fatal error. This will be signalled by
the flashing of all the LEDs.
This is followed by the stable signalling of operational status
The test routine can be repeated at random without this leading to any variation in
the switching status of the FSA-PLUS Switcher.
There the FSA-PLUS Switcher is turned off and then turned on again after a waiting time of approx. 5 seconds. The signalling occurs once again as described
above.
In double mode, after the central FSA-PLUS Switcher has been switched on, a
comparison is made of the number of recognised moving cards (MOC) of both
FSA-PLUS Switcher. In the event of an unequal number of recognised moving
cards, an alarm is activated.

7.6 Refresh
The FSA-PLUS Switcher carries out a refresh process every 20 hours. This process is a test routine to test the availability of all the moving cards. In this test routine, all moving cards are switched once again to the side on which they just find
themselves. This process has no influence on the switched connections. The
monitoring of failures is carried out up to the driver of the relay. A direct monitoring
of the delay is not supported.
The recognition of a defective moving card activates an alarm. A reverse switching
is not possible then.
8 General Characteristics and References

10 Trouble-shooting
There is always an alarm when LED 1 is activated for a collective alarm.
Every other type of status in the signalling reflects normal operation in the corre-
sponding configuration.
Example: The LED 11 lights up in manual mode and selected local reversing
switches permanently when the interface is not connected. The FSAPLUS Switcher recognises the interruption of the loop on this interface.
Due to the activated local reversing switch, this information will not be
used for control. This signalling is only used for information.
