Figure 3-5. 110A-Type 300-Pair Terminal Block
The 110A-type hardware can be used for the Trunk/Auxiliary Field and all Distribution
Fields (port, auxiliary, and station). The 110A-type hardware used with the system is
described below. The use for each type of terminal will be described later.
110AE1-75FT Terminal Block—A set of parts to permit field termination of cables on
a 100-pair wiring block (110AW1-100) that provides termination for 8 three-pair and
12 four-pair circuits.
110AB1-100FT Terminal Block—A set of parts to permit field termination of cables
on a 100-pair wiring block (110AW1-100) that provides termination for 24 four-pair
circuits.
110AC1-100FT Terminal Block—A set of parts to permit field termination of cables
on a 100-pair wiring block (110AW1-100) that provides termination for 32 three-pair
circuits.
110AB1-300FT Terminal Block—A set of parts to permit field termination of cables
on a 300-pair wiring block (110AW1-300) that provides termination for 72 four-pair
circuits.
