Lab Report

1. The term pinout refers to which pairs are terminated to specific pins on a connector.

2. What are the following cable types used for and how are they made? How are they different?

A cross over cable is made by terminating a 4 pair UTP cable using 568-A on one end and 568-B on the other end. This type of cable is used when connecting “like” devices such as connecting one computer directly to another computer.

A rollover cable is made by reversing the pinout or terminating it the complete opposite on one end of a 4 pair UTP cable. For example, one end of the cable the w/brn brn pair is on pins 7 and 8. On the other end of the cable the w/brn brn is terminated on pins 1 and 2. This type of cable is typically used to console into a switch or router.

A straight through cable is made by terminating both ends of a 4 pair UTP cable exactly the same. This type of cable can be used as a patch cable.

3. The pinouts for 568-A and 568-B are as follows:

568-A 568-B

Pin 1 - w/grn Pin 1 – w/or

Pin 2 - grn Pin 2 - orange

Pin 3 - w/or Pin 3 - w/grn

Pin 4 - Blue Pin 4 - blue

Pin 5 - w/bl Pin 5 - w/bl

Pin 6 - orange Pin 6 - green

Pin 7 - w/brn Pin 7 - w/brn

Pin 8 - brown Pin 8 - brn

The only difference is where the white green, green and white orange, orange are terminated. The only pins that change between the two standards are 1, 2, 3 and 6.

4. There are four pairs and a total of 8 wires in a UTP cable

5. The colors used on a UTP cable are white/blue, blue, white/orange, orange, white/green, green and white/brown, brown.

6. A punch down tool is used to terminate UTP cable into punch down jacks. It is also used to terminate UTP cables on to punch down blocks. The punch down jack has insulation displacing conductors which are v shaped conductors that cut into the outside of the pvc jacketing of the cable to make contact with the copper.

7. Cross...
