Priority Handling of priorities ( see Section 9.1 )
Own/Analog Selects the type of call station (ProCom or analog call stations).
Input/call station (Setting Own )

PTT line
Line (key) for the PTT key
Switches the AF to the module specified under Radio AF . (AF line of
the radio station)
The fixed AF channel specified under
Audio channel - Radio AF is

(see Table
Fixed audio channels of the DSS1 ) module
When pressing the PTT key, the
Line and the Flag (OUT) specified
under Transmit switch are activated.
Clear line The connection can be broken via this Line (key).
Tone call
To differentiate radio coverage, the Railway radio stations recognize three call tones (1520, 1750 and
2135 Hz). The
DSS1 module can detect and evaluate these sine frequencies. The Radio AF is therefore
switched permanently in idle mode to the fixed AF channel specified under Audio channel - Radio AF .
No DSS1 (e.g. 24LI)
The module specified by Address, Port, Section line is not a DSS1 . The
Tone call evaluation takes place externally.
Section line
When a call frequency is detected, the DSS1 module activates the
respective Line .
The lines are permanently assigned to the frequencies. (5=1520Hz,
6=1750Hz, 7=2135Hz)
(see Lines of the Module
DSS1 )
Audio channel - Radio AF
Fixed audio channels of the DSS1 module for reception (Audio channel
26 - 29) (depending on port)
DSS1 busy line No.
The DSS1 module is already active and no evaluation can take place.
( Line 1)
(see Lines of the module DSS1 )
Freely programmable if switched on externally.
