Abstract: A process for resolving call collisions in a digital conventional direct mode includes monitoring a direct mode communication channel for transmissions from other direct mode radios in the plurality of direct mode radios. In response to detecting a new call request: identifying a last radio to transmit on the direct mode channel, transmitting a new call request for receipt by the last direct mode radio to transmit, monitoring the direct mode channel for a response from the last radio to transmit, and if a call grant granting the new call request is received from the last radio to transmit, initiating the new direct mode call on the direct mode communication channel. If the call grant is not received, at least temporarily refraining from initiating the new direct mode call.

Abstract: A converged communication device comprises a first processor operable using a first communications protocol and a second processor operable using a second communications protocol. The first processor is configured to detect a factory reset. The factory reset selectively enables one of a multi-tier factory reset comprising: a factory reset of both the first and second processor; a factory reset of the first processor only; and a factory reset of the second processor only. The configuration may be triggered by an external input to the converged communication device.
