DSS1
Digital Speech Memory Module
The module DSS1 makes it possible to save recurring verbal announcements and
to output them on call stations and loudspeaker circuits.
For this there are eight memory banks available each on RAM and flash chips.
The module has four independent sets which can all be run in different modes of
operation. This way different functions can be realized on a DSS1.
Each set can simultaneously access each of the 2 x 8 memory banks.

Application example for the DSS1 with PA and intercom systems
The
DSS1 module can be used as speech memory in all DVS-21 applications in
which a minimum of a call station or a loudspeaker circuit (LK) are included.
The DSS1 module is used, for example, as ringing tone detector for switching on of
radio modules at Deutsche Bahn AG. Here preset sound frequencies are detected
and correspondingly interpreted.

Here the following allocation applies:
• Set 1 low frequency: Recording VKW 26 and
playback VKW 22
• Set 2 low frequency: Recording VKW 27 and playback VKW 23
• Set 3 low frequency: Recording VKW 28 and playback VKW 24
• Set 4 low frequency: Recording VKW 29 and playback VKW 25
