Daniels Electronics P25 digital fixed station interface enhanced

An enhancement to the P25 digital fixed station interface, in accordance with the TIA P25 fixed station interface standard, has been announced.

It broadens the suite of features within the scope of the DFSI standard for direct digital connection from the company’s LMR radio to P25 dispatch consoles.

The enhancement includes additional features specified in the TIA standard, including local repeat functionality, call alerts, radio check, radio stun/revive, radio monitor and emergency alert.

The company’s digital universal interface card provides the P25 DFSI connection via ethernet from the MT-4 P25 radio system to other LMR subsystems, such as IP-based dispatch consoles in a P25 network.

In accordance with the TIA P25 general system model, this interface interconnects the fixed station (Daniels radio) to a console or RF subsystem at the Ef connection.

The ethernet universal interface provides the P25 encoded (and optionally encrypted) digital audio signal directly to the console, as well as a suite of control signals.

This allows the dispatch console to see and manage all information associated with a call in an IP format, including unit and emergency IDs.
