The 110P-type hardware can be used in the equipment room for the Trunk/Auxiliary and all
Distribution Fields (port, auxiliary, and station). The 110P-type hardware used with the
system is described below. The use for each type of terminal block will be described later.
110PB1-300CT Terminal Block—A factory-assembled 300-pair connectorized terminal
block that provides termination for 72 four-pair circuits. Twelve 25-pair female
miniature ribbon connectors are located at the top of the terminal block. The
connectors are factory-terminated on the wiring block in continuous numerical order.
110PC1-300CT Terminal Block—A factory-assembled 300-pair connectorized terminal
block that provides termination for 96 three-pair circuits. Twelve 25-pair female
miniature ribbon connectors are located at the top of the terminal block. The
connectors are factory-terminated on the wiring block in continuous numerical order.
110PB1-300FT Terminal Block—A set of parts to permit field termination of cables
on a 300-pair terminal block that provides termination for 72 four-pair circuits.
110PC1-300FT Terminal Block—A set of parts to permit field termination of cables
on a 300-pair terminal block that provides termination for 96 three-pair circuits.
110PE1-300CT Terminal Block—A factory-assembled 300-pair connectorized terminal
block that provides termination for 32 three-pair and 48 four-pair circuits. Twelve
25-pair female miniature ribbon connectors are located at the top of the terminal
block. The connectors are terminated on the wiring blocks in continuous numerical
order.
110PE1-300CT/FT Terminal Block—A partially factory-assembled 300-pair terminal
block that provides termination for 32 three-pair and 48 four-pair circuits. Four 25-
pair female miniature ribbon connectors are located at the top of the terminal block
to provide connectorized termination to the 3-pair circuits. The connectors are
terminated on the 3-pair wiring block in continuous numerical order. The 4-pair
wiring blocks are provided as a set of parts to permit field termination of the 4-pair
circuits.
110PE1-300FT Terminal Block—A set of parts to permit field termination of cables
on a 300-pair terminal block that provides termination for 32 three-pair and 48 four-
pair circuits.
110PB1-900CB Terminal Block—A factory-assembled 900-pair connectorized terminal
block that provides termination for 216 4-pair circuits. Thirty-six 25-pair female
miniature ribbon cables are located at the bottom of the terminal block. The cables
are factory-terminated on the wiring blocks in continuous numerical order and
extend 40 inches from the bottom.
110PC1-900CB Terminal Block—A factory-assembled 900-pair connectorized terminal
block that provides termination for 288 three-pair circuits. Thirty-six 25-pair female
miniature ribbon cables are located at the bottom of the terminal block. The cables
are factory-terminated on the wiring blocks in continuous numerical order and
extend 40 inches from the bottom.
110PB1-900CT Terminal Block—A factory-assembled 900-pair connectorized terminal
block that provides termination for 216 four-pair circuits. Thirty-six 25-pair female
miniature ribbon connectors are located at the top of the terminal block. The
connectors are factory-terminated on the wiring blocks in continuous numerical
order.
