Abstract: A P25 radio can be configured to implement a key management facility to thereby manage keysets for and provision the keysets on other P25 radios in a communications system. The P25 radio, as a radio, can directly communicate with the other P25 radios to provision keysets in accordance with the OTAR protocol. The P25 radio may also be configured to function as a key fill device to thereby provision keysets manually on any of the other P25 radios to which it may be physically or wirelessly connected. The P25 radio may also be configured to use the keysets to communicate securely with any of the other P25 radios.

Abstract: A device and method for adjusting speech intelligibility at an audio device is provided. The device comprises a microphone, a transmitter and a controller. The controller is configured to: determine a noise level at the microphone; select a voice tag, of a plurality of voice tags, based on the noise level, each of the plurality of voice tags associated with respective noise levels; determine an intelligibility rating of a mix of the voice tag and noise received at the microphone; and when the intelligibility rating is below a threshold intelligibility rating, enhance speech received the microphone based on the intelligibility rating prior to transmitting, at the transmitter, a signal representing intelligibility enhanced speech.

Abstract: A secure digital format card that includes two interfaces to a processor is provided, comprising a housing, and a processor that includes a secure digital input/output (SDIO) interface, a second interface, and further connections different from the interfaces. A first set and second set of pads are located at the housing, a subset of the first set for communicating with the processor via the SDIO interface. A subset of the second set for communicating with the processor via the second interface, and a further subset of the second set for communicating with the processor via the further connections. The processor is configured to: enable the subset of the second set of pads via the second interface when enable data is received via the one or more further connections, from the further subset of the second set of pads.
