single spark twisted pair !!!!!!

Matching RJ45 wire numbers (1 2 3 4 5 6 7 8)
P1 = 4 and 5 (for the phone company)
P2 = 3 and 6
P3 = 1 and 2
P4 = 7 and 8
The comment splitter phone can induce a command error, which is my case !!!!.

I was looking out 4 telephone lines from the same line, not to pass 4 telephone lines in a RJ45 socket.

So if you want to explode a telephone line 4, do not order this article.
This product is only used to spend 4 phone lines on a single RJ45 cable.
The RJ45 cable has 8 son, and the phone only uses 2.
2 (son) x4 (phone) = 8 son.
