Type Connecting Blocks
Three-pair station circuits are run from the equipment room to the
satellite closet white field and four-pair station circuits are run from the
satellite closet blue field to the information outlets. Connections to both
the three- and four-pair circuits can be made with connectorized or
field-terminated cables depending on the type of connecting blocks
used.
Labeling
Figure 4-6 shows the fill direction for the blue and white fields at a
satellite location. Lead designations are written on the connecting
blocks using a permanent felt-tipped pen as described in Chapter 3 in
the section Labeling the Cross-Connect Field.
