4. CROSS-CONNECT JUMPER ROUTING RULES
A.Cross-Connect Cabling
4.01Cross-connect jumpers should be routed as
shown in Figure 2. Whenever a cross-connect changes
direction, it should do so at a point where a ring, tray
or fanning strip is placed. This allows the cross con-
nect to be dressed neatly without strain or interference
with any other portion of the bays.
4.02All cross connect jumpers should use the hori-
zontal cable ways between bays, and vertical cable
ways within bays. To prevent unnecessary jumper
buildup and congestion, all discontinued cross con-
nects should be removed from the DSX cable ways.
Jumpers should be sized to the proper length, including
a maximum of 3 inches of slack at each end.
