1 Introduction
The following technical manual describes a safety transfer (switchover) switch as
part of the FSA-PLUS family (FSA Switcher —Flexible, Safe, Automatic). The
transfer switch can also reverse all standard communication services with a
bandwidth of up to 60 MHz. The restrictions of the connected services are to be
found within the framework of category three and/or the former category four.

ISDN Primary Rate,
64 kbit/s and 2 Mbit/s and 1.5 Mbit/s permanent leased line
High speed Digital Subscriber Line (HDSL)

Data services, which satisfy the following boundary conditions, can also be con-
nected:
Max. connectable voltage
1
220 VAC / 200 VDC
2
Max. connectable current 11 A 2
Max. connectable power 160 WAC / 30 WDC 2
Max. bandwidth < 60 MHz
LSA-PLUS lines are fitted without primary protection elements for the termination
of the service cable (coming and going).

For reasons of electrical safety in case of accidental contact, only homopolar earthed TNV sig-
nals (telecommunication network voltage) or SELV signals (safety extra low voltage) are permit-
ted in accordance with EN 60950 !

Passing over these limiting values leads to the destruction of the device!

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 cop-
per 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 sys-
tem 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 al-
ways jointly switched over.
The interaction of the two FSA-PLUS Switchers is carried out by means of a per-
manent 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 de-
vice 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.
