Installing the Krone cross-connect system (UK)
In the Krone cross-connect system, one terminating strip holds ten pairs of
cable. When cross-connecting a 25-pair cable on this system, eight of the
ten terminating points are used on each strip. One 25-pair cable, therefore,
occupies three terminating strips:
8 pairs per strip by 3 strips = 24 pairs
