9.7 Intercom radio 2
Program to switch on radio stations with differentiation of frequency bands when using the DSS1 module
in the DB-Radio (Tone call) mode
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)
Address, Port, Line
Address and port of the module to which the call station is connected
and the line (key) in use. (4NSA)
Input/call station (Setting Analog)
Address AF, Port
Address and port of the module to which the AF line of the call station is
connected. (4NPA)
Address 24LI, Port, Line
Address, port and line of the module to which the control line of the call
station is connected. (24LI)
Keying line
Keying in frequency band.
(Key is illuminated continuously, PTT key flashes)
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
used. (26/27/28/29)
(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.
