VIdeo shows how to setup, terminate, punch down, and make cross-connects on a 110 block. 110 blocks are frequently used as distribution for PBX stations and Telephone company. They have one major advantage over 66 blocks in that the connections are more densely concentrated. Therefore, they take up less space. However, they do lack some of the versatility of 66 blocks. Even though 66 blocks are are larger, there are more ways to make cross connects. For instance you can connect two sets of wires to a Telco line on a 66-block. While on a 110, only one punch-down connection can be made per wire slot. 110 Blocks are like two layers. First layer is the source wiring (telephone lines or PBX ports) fanned out. Then 110 wafers are then punched-down on top of that using a multi-punch tool. Finally, wiring that feeds to inside connections (Station cabling, extended demarc) is punch down after that. Usually the rear layer of wiring is from a telephone demarc. Then, the extended wiring (inside wiring) is punch on the outer connection.

This video briefly shows the use of a 5-pair impact tool for doing terminations on 110 blocks. This tool terminates the 4 or 5 pair 110 wafers all at once. Without this tool, you would traditionally have to use a 110 punch tool to do each wire at a time. In the right hands and for the right situation, this cool could cut cable termination time in HALF! Tool Fluke Networks D-Impactor 5-pair Impact Tool (10059000) DOES NOT require a hammer. Many that I have seen, require you hit the back with a hammer. This one is spring loaded and doesn't require a lot of effort on the part of the technician.
