No clue about details but this is what we have so far:
"During the tests also confirmed the high efficiency of the new means of communication and a set of electronic warfare (EW) "Vitebsk-25." The complex, in particular, is equipped with a modern digital Jammer (TSSAP) A-370-3C, and can not only assess the radiation enemy radar, but also "inhibit" signals in a wide frequency range. In addition, the complex includes protection against missiles targeting the thermal head, which blinds the enemy ammunition with a laser beam."
Though posters here think it is domestic version of President-S.
