TASI LOCKING FREQ:
TASI ( TIME ASSIGNMENT SPEECH INTERPOLATION ) IS
USED ON SATELITE TRUNKS, AND BASICALLY ALLOWS MORE THAN ONE
PERSON TO USE A TRUNK BY PUTTING THEM ON WHILE THE OTHER
PERSON ISNT TALKING. OF COURSE, YOU'D NEVER HEAR THE OTHER
PERSON TALKING ON YOUR TRUNK.
WHEN YOU START TO TALK, HOWEVER, THE TASI CONTROLLER HAS TO
FIND AN OPEN TRUNK FOR YOU. BECAUSE OF THIS, SOME OF YOUR
SPEECH IS LOST( BECAUSE OF THE DELAY IN FINDING A TRUNK)
THIS IS CALLED CLIPPING.
WELL, IF YOU WERE TRANSMITTING DATA OVER A TRUNK,
CLIPPING WOULD REALLY FUCK UP THE DATA. SO THERE IS SOMETHING
CALLED A TASI LOCKING FREQUENCY WHICH KEEPS THE TASI FROM
PUTTING ANYONE ELSE ON YOUR TRUNK OR YOU ON ANYONE ELSES
TRUNK. IN ANY CASE THE FREQ. IS 1850 HZ. SENT BEFORE THE
TRANSMISSION).
