RTU-292 Operations Manual
1.3.4 OPTIONS
RTU-292 options include the: The Voice Prompt Option, which gives verbal prompts to the
user as an aid in all aspects of unit operation; The Local Phone Option, which allows a DTMF
telephone set to be plugged into the unit, allowing control and access from the phone set; and
the VMM-100 module, used to add VMR (Voice Modulation Recognition) and DSP noise
reduction capability. Among the Software Options are the Squelch Break Access Option,
which allows a radio to contact the system via series of squelch breaks and the DTMF Access
Option, which allows a radio user to contact the system via a DTMF keypad. Other Software
Options include Call Logging and Remote Control of an URC-200 radio. Various spares kits
are also available. The STU-III option allows a STU-III phone to be connected to the RTU-
292. This allows an encrypted STU-III conversation to be decrypted at the RTU-292. The
decrypted signal is patched into the connected radio system.
