Cross Connect Drawers
The cross connect drawers provide extra flexibility when provisioning channels.
The cross connect drawer is a separate unit supporting 8 channels for a total of
two channel bands in a protected system. The system is expandable in channels of
8. To cross connect 16 channels, use two cross connect drawers. To cross connect
32 channels, use four cross connect drawers with two cable storage drawers. See
Figure 1-1 .
Table 1-17 lists the equipment you need if you are using the cross connect drawer
in a protected system using line card motherboards with splitter. Table 1-18 lists
the equipment needed if you are using the drawer system in an unprotected system
using line card motherboards without splitter.
Cable Storage Drawer
The cable storage drawer should be installed immediately beneath the chassis.
(See
Figure 1-19 .) Cables connect the MTP connectors on the motherboards are
routed in, through, and out the other side of the cable storage drawer.
