Chapter 6
Additional Performance Enhancement
The following performance enhancements are some of the latest creations designed to enhance the
security, quality, and efficiency of the radios.
6.1

ASTRO 25 Enhanced Data

ASTRO 25 Enhanced Data is optimized to handle different message sizes and variable update rates
from different applications of the radio. To improve data channel efficiency and enable denser network
traffic, add Enhanced Data to the Integrated Data system with a software installation.
6.2

Dynamic System Resilience

Dynamic System Resilience (DSR) ensures that the radio system is seamlessly switched to a backup
master site dynamically during a system failure. DSR also provides indications such as failure
detection, fault recovery, and redundancy within the system. DSR also supports mechanisms related to
the Integrated Voice and Data (IV&D), or data centric.
6.3

CrossTalk Prevention

CrossTalk Prevention feature prevents crosstalk scenarios and allows the adjustment of the internal
SSI clock rate of the radio. This reduces the possibility of radio frequency interfering spurs.
6.4

Encrypted Integrated Data

Encrypted Integrated Data (EID) provides security encryption and authentication of Integrated Voice
and Data (IV&D) bearer service. This bridges the communication between the radio and the Customer
Enterprise Network.
6.5

SecureNet

SecureNet allows you to perform secured communications on an Analog or Motorola Data
Communication (MDC) channel.
6.6

P25 Digital Vehicular Repeater System

Motorola Solutions offers an MSI Certified APX compatible, third party, P25 Digital Vehicular Repeater
System (DVRS). This provides low-cost portable radio coverage in areas where only mobile radio
coverage is available.
NOTE: Portable subscriber units enabled in the system for Radio Authentication shall be able to
authenticate regardless of whether they are communicating directly on the system or by using a
DVRS.
