Hi. I've been reading through many of the forum topics and some other sites. I see conflicting information on what type of cabling to use between the Smart Jack and the CSU/DSU.

Can I use a regular RJ45 male connector with the proper pinout and UTP, or must I use an RJ48 male connector with STP?

Can I simply use 4 wires from an existing 100 pair wire? Would this cause interference frame errors, etc...?

Also, are there any side effects of having a break the cable, connected in a punch down? If I do have a break, must I connect 7 & 8 to a ground? I didn't know if it was necessary to run have a home run from the Smart Jack to the CSU/DSU.

Sorry for all of the questions in one post.

Thank you in advance.
Jim
