The FBSAR board

Highlights

Provides interface to non-selective radio systems (1 base station)
Two relays for busy marking of external equipment and transmitter keying
Two optocouplers, which may be used for mutual busy marking
Provides interface to PA systems (2 PA zones)
DC termination of two subscriber outputs
Two filters to remove carrier for display data signals on two subscriber audio outputs
Second channel may be used as filter / PA adapter only
Galvanic separation between the exchange and the external equipment
If the relay is used, the FBSAR must be powered with +24V from the exchange

-It has filters that remove the display data carrier from the audio. In this way
-excessive heating of power amplifiers is prevented. It also provides DC
-termination of subscriber outputs (corresponding to non-display stations).
-For [[FBSAR - Mobile radio interface|interface to non-selective mobile radios]], it provides two relays that are
-controlled by [[RCO]] /c-wire for busy marking of the external equipment and control
-of transmitter keying. There are also two optocouplers that can be used for mutual
-busy marking.
-The board has two audio transformers that provide galvanic separation between the
-intercom exchange and the external equipment.
-The relays use [[Powering Additional Equipment|+24 V from the exchange]]. If the relays are not used, no power is
-required.
-The FBSAR is fastened onto the mounting rail on the connection field of the
-AlphaCom exchange.
