When the key has been loaded successfully, one of
the following scenarios occurs:
• You hear a short tone for single-key radios.
• You hear an alternating tone for multikey radios.
Multikey Feature
This feature allows the radio to be equipped with
different encryption keys and supports the DES-OFB
algorithm.
There are two types:
Conventional
Multikey
The encryption keys can be tied
(strapped), on a one-per-channel
basis, through Customer
Programming Software. In addition,
you can have operator-selectable
keys, operator-selectable keysets,
and operator-selectable key
erasure. If talkgroups are enabled
in conventional, then the encryption
keys are strapped to the talkgroups.
Trunked
Multikey
If you use your radio for both
conventional and trunked
applications, you have to strap your
encryption keys for trunking on a
per-talkgroup or announcement-
group basis. In addition, you may
strap a different key to other
features, such as dynamic
regrouping, failsoft, or emergency
talkgroup. You can have operator-
selectable key erasure.
