RDM-12 allows you to:
- to create 12 of the subscriber telephone channels and 1-remote service channel
- create 1 to 4 local phone calls
- bring together after three telephone channels to the four broadband channels for transmission of telegraph signals at speeds up to 16 000 Bd
- bring together all 12 channels into a single broadband channel for transmission of telegraph signals at speeds of up to 48 000 Bd
- assign to any participant of the telephone channel by using the device of the tonal telegraphy STT one telegraph channel
- using the phone utajovacího device may be any participant of the telephone channel used for the transmission of classified phone call
