Priority Channel Marking |
(Scan Wide, Conventional) |
Enhances Priority
Channel Scan performance
by causing unqualified Priority Scan List
Member transmissions to be "Marked" and temporarily removed
from the scan list. This is particularly
effective when in Landed Scan
Mode on a non-priority scan list member, and when the radio briefly
mutes at specific time
intervals to check for Priority Member
1 or Priority Member 2 Member activity.
This temporary Scan
List Member removal allows this muting period to be a shorter amount of
time, and a shorter interruption for the current call. This feature applies
only
to Conventional
scan list member channels.
|
An analog Priority Channel is ’Marked' when it is unsuccessfully scanned due to no TPL / DPL (PL) code where a PL code was expected, or where the PL code was incorrect. |
|
A digital (ASTRO System) Priority Channel is 'Marked' when it is unsuccessfully scanned due to no Network Access Code (NAC) where a NAC code was expected, or where the NAC code was incorrect. |
|
Once the PTT button is pressed, or when scan finds that carrier has dropped on a ’marked’ Priority channel, or the proper PL/NAC is detected on the 'Marked’ channel, then the ’Marked’ status is removed for that Priority channel and normal priority scanning is resumed. |
|
Analog and digital are determined by the Rx Voice / Signal Type field setting on a per channel basis. |
