Group Alias Update
Group Alias update is a message sent to a given Talkgroup while on a voice channel to
alert the receivi
ng radio of the transmitting radio’s alias/ID configured in the Provisioning
Manager on the console. The updated Group Alias data is received by the members of
the Talkgroup and their Unified Call List (UCL) is updated. The DVRS passes the Group
Alias Upda
te to the local ‘DVRS Enabled’ PSUs so that their UCLs can get the update
even while they are not directly connected to the trunked system but are proxied via the
DVRS.
NOTE:
The updated Alias will be displayed on the receiving PSU only when the PSU is directly
affiliated on the trunking system. When affiliated through the DVRS, the PSU will still
display the Unit ID of the transmitting PSU but it will not display the programmed or the
updated Alias for that transmitting Unit ID.
NOTE:
When the MSU is operating on TDMA mode, the MSU may receive group services but
will not proxy those to the DVRS / Local PSUs.
