System Wide Key Select

When the ASTRO OTAR field is "Enabled" for the current Trunking System, this Key Select value is chosen from the Secure Hardware Encryption Key References List of the Secure KMF Profile selected in the KMF Profile Index field for the current Trunking System.

Be aware that the CPS is actually pointing to the Keys of the Encryption Key List for this selection; individual Keys from the Secure Hardware Encryption Key References List reference the Encryption Key List's Keys from the Hardware Key Reference field. Therefore any key selected when ASTRO OTAR is enabled must first be defined in the Secure Hardware Encryption Key References List.

When the ASTRO OTAR field is "Disabled" for the current Trunking System, this Key Select value is directly chosen from the Secure Wide Window's Encryption Key List.
