Assume having $8$ lines fed to a multiplexer; each creates $2K$ bits per second. If the interleaved unit is $2$ Bytes, with no synchronization bits has been added to the frames at the link, then

The duration of each output$-$unit in the Frame equals second.

$($Note: When writing the answer, you must use ONLY numbers, NO units, NOTHING else, and with NO spaces$)$
