The 110P-type hardware consists of 100-pair wiring blocks, separated
by horizontal patch cord troughs, mounted on a panel. The P-type
comes in both 300- and 900- pair configurations which can either be
connectorized or field terminated. The 110P-type terminal blocks are
made up of alternate rows of 110-type wiring blocks and horizontal
jumper troughs arranged in a vertical column with the troughs located
above the wiring blocks. At the bottom of the terminal block is a partially
closed duct. The field-terminated hardware must be assembled (troughs
and wiring blocks must be fastened to the back panel); the connectorized
terminals come fully assembled and ready for mounting. A 300-pair
connectorized terminal block is shown in Figure 2-6.
There are two types of 900-pair connectorized terminal blocks: one has
a connector field at the top; the other is connectorized with a 40-inch
length of cable terminated with a female 25-pair cable at the bottom
(Figures 2-7 and 2-8).
