What are the main types of punchdown blocks?
The most common punch blocks are the 66 and 110 blocks. The 66 block has been widely used for splicing 25 pairs of telephone wires together. Evolving from the 66 block for voice is the 110 block for data, which is made up of rows of four IDCs that are used to splice pairs together.
What is a 110 punchdown block?
110 block: A type of punch down block used to connect sets of wires in a structured cabling system. 110 is also used to describe a type of Insulation-displacement connector used to terminate twisted pair cables which punch-down tools.
Are 110 blocks still used?
A 66 block is an older style of phone block. They’re still used but 110 blocks allow for faster transfer speeds and can be used for networking or voice. A punch down tool can be a cut or non-cutting blade.
What is punchdown termination?
Both styles of punch block use a punch down tool to terminate the wires to the block. To terminate a wire, you place it into the terminal and then push it down to make contact with the punch down tool. The punch down tool fits around a 66 block terminal or into a 110 punch down block terminal.
Why is it called a 66 block?
The term 66 block reflects its Western Electric model number. The 25-pair standard non-split 66 block contains 50 rows; each row has two (E) or four (M) or six (A) & (B) columns of clips that are electrically bonded.
What is the purpose of a punchdown block?
A punchdown block is a mechanism used to cross-connect sets of wires through a metal peg system in telecommunications closets or local area networks (LAN). Solid copper wires are punched into short and open-ended slots that serve as insulation displacement connectors.
What is a 66 block used for?
A 66 block is a punchdown block containing rows of four IDC style clips. It is used for terminating 22-26 AWG solid copper cross-connect station wiring for many types of phone systems. Bridge clips are required to complete the circuit between the left and right side of the 66 block.
What is a punchdown block used for?
What is the main reason to use 110 blocks?
Advantages. 110 style blocks allow a much higher density of terminations in a given space than older style termination blocks (66 style or wire wrap) because of their stacking capability. Some 110 blocks meet specifications for higher bandwidth data protocols such as Category 5 and higher.
Which of the following are the two major parts of a Bix punchdown block system?
The BIX cross-connect system is primarily composed of two parts: the mounts, and the connectors.
What type of cable should be used on a 66 block?
66 blocks are designed to terminate 22 through 26 AWG solid copper wire.
