A Cipher Unit KY58 is connected and operated in baseband mode. For voice communication,
narrowband audio line NB1 and wideband audio line WB1 are used, carrier activation is per-
formed via keyline PTT_1L low-active. Modulation is in AM or FM. In addition, a Link 11 data
terminal is connected. Data communication is carried out via narrowband audio line NB2 and
carrier activation via keyline PTT_2 high-active. Modulation is in FM (see chapter 3.3.4).
