Series 1 or 4, etc)) Group count (number of four letter cipher groups in original German signal) Cipher indicator group showing which cipher was being used ( eg. Triton (Shark) or Bertok) and the group for obtaining message setting (starting position of rotor for that message) Allied name assigned to U-boat radio circuit   Series’ 1, 2 3, etc. were allied designations for various U-boat radio circuits.
