Data Sheet
DSS1
Digital Speech Memory Module
The following frequencies are available per default:
1520 Hz
1750 Hz
2135 Hz
Other frequencies are possible for special cases.
Variation "Speech Memory":
In this variation, three further modes of operation can be selected in the con-
figuration software:
- Speech Memory
- Sync Master
- Sync Slave
The features on the card depend on the mode of operation.
Mode of Operation "Speech Memory"
In this mode of operation texts can be recorded on one or several banks (up
to 60s for one text). Here the beginning and end of a speech recording are
precisely defined in terms of time, and public address is terminated when
the text ends.
The texts or tones are recorded in analogue form through a 4NSA on the
DSS1.
The RAM memory is designed for recurring announcements over a short
period of time. Texts can be recorded directly through a ProCom call station.
These are retained until the DVS-21 is switched off or until new texts are re-
corded over them.
Recording on the flash memory can only be done with a detour over the
RAM chip. It is possible to write announcements from the RAM directly into
the flash memory. The memory content of the flash chip is retained, how-
ever, also after the DVS-21 is switched off.
The option "write protection" can be activated in order to prevent uninten-
tional deletion of the flash memory.
The memory times are distributed as follows:
Memory
Type
Time /
Bank
Number of
Banks
Total Time
RAM volatile 7.5 s 8 60 s
Flash permanent 7.5 s 8 60 s
Flash - „ -
1 x 15 s
