wall with 2 screws. The cable from the DVS-21 central system is set up through 4 or
6 plug contacts.

DTA-xxxs are connected through the analogue low frequency (LF) interface module

out with a modem connection.

Busy indication, voice acknowledgments and call signals are indicated by the LEDs.
The display and blink behaviour of the LEDs can be programmed with the system
software ICS of the DVS-21.
