The signal input (IN) is reproduced at the outputs (T1-T10), shifted in time by an amount determined by the device dash number (See Table). For dash numbers less than 20, the total delay of the line is measured from T1 to T10. The nominal tap-to-tap delay increment is given by one-ninth of the total delay, and the inherent delay from IN to T1 is nominally 1.5ns. For dash numbers greater than or equal to 20, the total delay of the line is measured from IN to T10. The nominal tap-to-tap delay increment is given by one-tenth of this number.
