The MDC OTAR Page

(Secure Configuration, Secure Wide)

The MDC OTAR Page allows you to view or define MDC Over-The-Air Rekeying (OTAR) features. MDC OTAR features apply only when operating in secure encrypted mode and only for Conventional communications. In addition to Rekey Requests, OTAR transmissions include: Delayed Acks, and Power-up Acks. Some of the options selected may also need to be set up at the Key Management Controller (KMC) site to work properly.

	MDC OTAR is enabled on a per Conventional Personality by way of the Non-ASTRO Signaling Type field. The radio is further configured to initiate OTAR commands by enabling that Personality's OTAR Tx field.
	When a Secure / Clear Strapping field is set to "Select" for a certain channel, either the Secure Tx Select button-press, Secure Tx Select switch-toggle, or the Secure menu-selection allows the radio-user to toggle between Secure or Clear communications for that channel.

When the radio is a model / option capable.
