Q: We have set up our 10Base-T network with our station wire on 66E blocks and our concentrators on 110 blocks, running crossconnect wire to each station that needs connection to the local area network. By doing it in this way I`m able to keep our communications closets orderly. By the way, this is in a Category 3 wiring scheme. As we go to a Category 5 wiring scheme and 100Base-T, I would like to keep this wiring the same. I`m aware of Category 5 66E blocks and Category 5 crossconnect wire but

By doing it in this way I`m able to keep our communications closets orderly. By the way, this is in a Category 3 wiring scheme. As we go to a Category 5 wiring scheme and 100Base-T, I would like to keep this wiring the same. I`m aware of Category 5 66E blocks and Category 5 crossconnect wire but would I still be able to build our closets in the same way? I`ve seen what wiring closets can become after moves and changes using patch panels and cords and would like to continue to use crossconnect wire to do my moves and connections to the local area network.

A: Your approach, while unconventional, is certainly acceptable. While I agree that patch panels and patch cords can become a "rat`s nest," I question why you would want to continue using two different types of termination hardware (110 and 66 blocks) in the same closet. Your technicians must either carry two termination tools or be constantly changing blades. I would suggest that you choose one type of termination hardware and plan to use it throughout your new Category 5 cabling system.
