MR-1000 user guide V1.3

SATEL MR-1000 redundant master is designed for enhanced reliability in critical VHF /

UHF radio modem networks. SATEL MR-1000 features an automatic redundant controller

with two radio transmitters and up to four receivers (depending on configuration) operating

in hot standby redundant mode.

The redundant configuration of MR-1000 secures the communication even if a failure

occurs in one of the transceivers or power supplies. Redundancy combined with the SATEL

radio modem MTBF of more than 60 years provides utmost communication system

reliability.

The SATEL MR-1000 redundant master supports full remotely manageable network

diagnostic and configuration functionalities via SATEL NMS.
