Dynamic Channels
In this mode of operation, the DVIM processes Aegis calls that are not
assigned to dedicated channels. The DVIM assigns the call to the first
available non-dedicated channel. The only limitation with this mode of
operation is all dynamic channels must have the same DVIU key.
To configure a dynamic channel, change the channel equipped field for
that channel to a "Y" (this channel must be connected to a DVIU).
Leave the Group Alias and Group ID fields blank when the channel
equipped field is set to "Y" to indicate it is for dynamic allocation.
Dedicated Channels
Dedicated channels will always process calls assigned to that channel.
This allows DVIUs to be dedicated to Aegis groups. Therefore, a
system, agency, fleet or group call may be assigned a dedicated DVIM
channel, each of which may have a different DVIU cryptographic key.
For example, an agency may be assigned to channel 1 of the DVIM and
a group within that agency may be assigned to channel 2 of the DVIM.
The agency calls will be encrypted/decrypted by the DVIU connected
to channel 1 of the DVIM and the group calls will be
encrypted/decrypted by the DVIU connected to channel 2. The 2
DVIUs may have different cryptographic keys.
To dedicate a DVIM channel, set the Channel Equipped field to "Y"
and select the desired group from the Group Alias drop-down list box.
A warning message will be displayed if the group is already dedicated
to a DVIM channel.
Undedicate
Choose the
Undedicate
button to undedicate a channel. The channel
(if previously equipped) will become dynamic and the Group Alias and
Group ID fields will become blank.
Save and Send DVIM Configurations
When the channels are configured, the configuration must be sent to the
DVIMs. Each DVIM stores the database in its Non-Volatile RAM
(NOVRAM) so it will remain present after resets. The data does not
have to be uploaded again unless the configuration is changed or the
NOVRAM is reset on the DVIM. Action in both the
DVIM Channel Configuration dialog box and the
