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.
CrossTalk Prevention
This feature prevents crosstalk scenarios from
happening, especially when a wideband antenna is
used. This feature allows the adjustment of the
internal SSI clock rate of the radio. This subsequently
reduces the possibility of radio frequency interfering
spurs and prevents the issues of crosstalk.
Encrypted Integrated Data (EID)
EID provides security encryption and authentication
of IV&D data bearer service communication between
the radio and the Customer Enterprise Network.
SecureNet
SecureNet allows user to perform secured
communications on an Analog or Motorola Data
Communication (MDC) channel. The MDC Over-the-
Air Rekeying (OTAR) feature will allow users to
perform OTAR activities on an MDC channel.

Conventional Talkgroup and Radio Scan
Enhancements
A few enhancements have been made to the
Conventional Talkgroup at the system. These
enhancements improve the Scan feature operation
significantly when multiple agencies are using a
single conventional radio frequency channel. These
enhancements allow users to use Selective Squelch
to operate on only the subset of talkgroups that are
relevant to the users rather than all talkgroups on the
channel. These Scan improvements have been made
to eliminate the audio holes that were present and to
turn on the busy LED when activity is present on the
channel. Mixed Vote Scan and Standard
Conventional Scan configurations are supported.
Priority Operation is also supported.
Up to 30 different talkgroups can be supported using
conventional channels. A maximum of four talkgroups
can be supported when Vote Scan channels are
being used.
Smart PTT is supported with this enhancement as
Smart PTT prevents users from transmitting while
other users are on the channel.
