Theorem Lopez

Product : Structured cabling.
Part involved : category 5 and category 5e.
Summary : The pipe is full without space to tending another utp cabling. It needs to dig into wall.
Scenario : The new data port will be installed at some office, but this office has 4 data port working and they need to install one more.
Company : Institute of cancer illness - INEN.
Reference date : January 2004

My co-worker Erick Lopez gave me the guideline to resolve the trouble, that is the reason that i called "Theorem Lopez"; he considered to reassign the wired functions into utp cable to reach with solution. Be very carefull because I tested with success but solution is out of the standard EIA 568A and EIA 568B and works but up to 10Mbps, no more. Up to this time I did not see any like that we suggested next :

1.- In category 5 and category 5e wired 4,5,7,8 are not used, only if the jack connector works as data port.

2.- Into one utp cabling we are going to carry two computer data signal.

3.- The first computer is assigned to wired 1,2,3,6

4.- The second computer will be assigned to wired 4,5,7,8

5.- At the patch panel side and the face plate side (computer) we need to install two RJ45 Plug at every side of the cable. Then the cable will start with two RJ45 plug and the same cable will end with two RJ45 plug, that is in both sides.

/**Working on one side of the cable, after that repeat the same procedure in the other side.**/

6.- The first RJ45 plug should be conectorized following the order of wired (1,2,3,6) while the rest of wired (4,5,7,8) they would be go empty into RJ45 pin position.

7.- The second RJ45 should follow the next positions : wired 4 into position1, wired 5 into position 2, wired 7 into position 3, wired 8 into position 6. Position means the number of pin into RJ45 plug.

8.- At telecomunication room, put one patch cord for every extension of RJ45 plug to establish connection through port switch

9.- At work area extend every RJ45 plug through patch cord connection to computer.

Considered it as temporary solution while you are looking to migrate or implement your solution according to the international standards of structured cabling.
