although some accessories and assemblies are certified to lower categories. The
usual caveats apply to maintaining pair twist up to the point of termination, as with
the other systems.
Krone Connecting Blocks.
The Krone (pronounced krohn´-ah) connector system,
shown in Fig. 7.11, features 8-, 10-, and 25-pair basic connector modules that can
be mounted in several configurations. The 8- and 10-pair connectors can be
installed in separate module mounts that each have a capacity of 20 connectors.
These mounts can therefore terminate a total of either 160 or 200 pairs. The 8-pair
connector is typically used to terminate two 4-pair station cables. The module
mounts can be individually wall-mounted or can be installed in triples in a 19-inch
wall or rack-mount frame. For 25-pair applications, a 25-pair connector and mount
is available.
The 25-pair connector module is a feed-through design with a front and back
piece, similar to the 110 system. As with the 8- and 10-pair connectors, the 25-pair
connector is installed horizontally into its mounting bracket. A special assembly of
two of the 25-pair connector modules is available with a mounting bracket that is
the same size and footprint as the standard 66 block. These assemblies terminate 50
pairs, as do 66 blocks, and are ideal for replacement of the older blocks for higher
