Configuration Related to a KMF Profile
Up to 5 KMF Profiles (for 5 units) can be created by using KPG-D1/ D1N.
In a P25 Conventional system, a KMF Profile is configured for each Personality. The multiple KMF Profiles created can be
used separately for each Personality.
In a P25 Trunking system, a KMF Profile is configured for each system.
The following are the functions related to the KMF Profile used for OTAR:

0
KMMs which are encrypted and authenticated
0
KMMs which are only encrypted
