OTAR Generate Key-Loss Key |
(Secure Wide, General) |
Enables the radio to automatically transmit
a Key-Loss Key signal notifying the ASTRO
OTAR (Over-The-Air-Rekeying) Key Management Facility (KMF) or the MDC OTAR Key Management Controller
(KMC) that the radio needs a new encryption key. This new encryption key
is used for encrypting OTAR messages. Once the Key-Loss Key signal is
received, a new encryption key is transmitted to the radio for the purpose
of receiving additional encryption keys. OTAR is possible from an MDC
or ASTRO - Conventional channel, or an
ASTRO 25 - Trunking
channel.

When the Secure Operation field is set to "Hardware", and
when the OTAR Enable field is enabled, and
when the radio is model / option capable.
When disabled, the OTAR rekey of the
radio is prevented if the radio loses all of its keys.
