Run the telephone cable underneath the field-terminated block.
Strip 12 inches (31 cm) of jacketing off the cable, exposing the

Make sure each pair keeps its twist up to the index strip. (Each
pair is split by a raised tooth on the index strip.)
Use the 788J1 impact tool to seat and trim the conductors. See

Continue seating and trimming conductors from left to right for
