BIX blocks
BIX blocks are used to interface between inside and outside cables in multi-tenant or commercial buildings.
They are also common in large homes with many inside wire runs to a "star connection" point. In these
environments, they represent the demarcation point. They are designed to be installed in a business
entrance terminal (BET), metal inside terminal (MIT) box, an indoor closet or equipment room. They are also
used occasionally in pedestals.
BIX blocks replace legacy R66 Quick connect terminations. They are laid out to count from left to right.
Connectors have a slip-in fitting that automatically strips wire as it is punched down.
Cables can enter the mount from either the top or the bottom. BIX blocks feature back to back connections.
The standard identification for BIX blocks is green labels for feeder pairs and blue labels for distribution or
house pairs; however, this standard is not always followed. If your work changes their designation, you
should be sure to update these circuit labels.
Pair 1 is always on the extreme left side and pair 25 is on the right side. The tip is the left side of the
protrusion and the ring is the right. There are different types of BIX blocks, single pair and multiplied strips, so
it is important to use the correct type for the application.
110 blocks
The 110 block is a type of punch block used to connect sets of wires in a structured cabling system. The "110"
designation is also used to describe a type of insulation-displacement connector that terminates twisted pair
cables. It uses a punch-down tool, similar to that used for BIX blocks.
110 blocks are laid out to count from left to right, like BIX blocks.
On the 110 block, wires are fed from the front, and (like BIX blocks) the 110 features back to back
connections.
R66 blocks / Quickconnect
The R66 is a legacy block that you may see in multi-tenant or commercial buildings, although it has been
increasingly replaced by the BIX block. The R66 uses a special tool to punch in wires. The pins are connected
together in either horizontally or in a two-level fashion.
R66 blocks are laid out to count from top to bottom.
The 66 block is designed with contact accessibility from the front, and wires are fed in from the side.
