66 block wiring cross connect voice or data to a proper punch down. Telco or
voice cross connecting of pairs can be done on 66 blocks.
1 pair or more can be connected to the block. Cross over clips can be used to connect the
pair coming in to the block to the pair leading out of the block.
Mount these on the wall of your equipment room or phone closet and punch
down all the phone connections you need, and expand from block to block with
wiring clips. Most units come with their own wall mount
bracket. Usually phone lines will be punched on the left and cross connected
to the right of the block. Bridging clips are used to complete the connections.
