Viking VM600 Mobile Radio Operating Manual

Secure Communication (Encryption)
- The data channel icon goes out (once the radio returns to a control channel), but the
data context icon stays on.
If the data context icon is not on, you do not have an SNDCP context (i.e., you are not data
registered).
Once the radio has a data context, if it is configured for OTAR and has a UKEK, it will
attempt to OTAR register. Depending on timing, the radio may stay on the data channel
for a longer period of time (the second step above) while it OTAR registers, an action
which can kick off an OTAR update procedure. Eventually the radio will leave the data
channel. The radio will be told by the system when it should the data channel.
A sign that has not successfully OTAR registered is that the radio’s data context icon will
be on, but the radio will periodically keep going back to the data channel (the data channel
icon will periodically come ON and then OFF). The number of times the radio will
attempt to OTAR register and the amount of time it will wait between events is configured
in Armada.
