Motorola Solutions Inc. 92FT4896 ユーザーズマニュアル

The following special notations identify certain items:

The following are some of the latest creations designed to 
enhance the security, quality and efficiency of APX radios.

DSR ensures the radio system is seamlessly switched to a 
backup master site dynamically in case of system failure. 
DSR also provides additional indication e.g. failure detection, 
fault recovery, and redundancy within the system to address to 
the user in need. Mechanisms related to the Integrated Voice 
and Data (IV & D) or data centric are all supported by DSR.

This feature prevents crosstalk scenario from happening, 
especially when a wideband antenna is used. This feature 
allows the adjustment of the Trident Transmitting SSI clock rate 
in the radio to be varied from the Receiving Frequency. This 
subsequently reduced the possibilities of radio frequency 
interfering spurs and prevents the issues of crosstalk. 

EID provides security encryption and authentication of IV & D 
data bearer service communication between the radio and the 
Customer Enterprise Network.

SecureNet allows user to perform secured communications on 
an Analog or Motorola Data Communication (MDC) channel. 
The MDC OTAR feature will allow users to perform OTAR 
activities on an MDC channel.
