The cable constructed will be a 4-pair "straight thru" cable. A straight thru cable means that the color of wire on one pin on one end of the cable, will be the same as the corresponding pin on the other end. The cable will be wired to TIA/EIA-568-B or A standards for 10BASE-T Ethernet, which determines what color wire is on each pin. T568-B, also called AT&T specification, is more common in the United States. Many installations are also wired to T568-, also called ISDN. Prior to starting the lab, the teacher or lab assistant should have a spool of Cat 5 Unshielded Twisted Pair (UTP). | Cisco SrsTEMS Lab Straight-Thru Cable Construction Objective Build a Category 5 or Category 5e CAT 5 or 5e Unshielded Twisted Pair UTP Ethernet network patch cable or patch cord. Test the cable for continuity and correct pinouts the correct color of wire on the right pin. Background The cable constructed will be a 4-pair straight thru cable.

Prior to starting the lab the teacher or lab assistant should have a spool of Cat 5 Unshielded Twisted Pair UTP cable RJ-45 8-pin connectors an RJ-45 crimping tool and an Ethernet RJ-45 continuity tester available. Work individually or in teams. The following resources will be required One to .9 m 2 to 3 ft length of Cat 5 cabling per person or team Four RJ-45 connectors two are extra for spares RJ-45 crimping tools to attach the RJ-45 connectors to the cable ends Ethernet cabling continuity tester which can test straight-thru or crossover type cables T568-A or T568-B Wire cutters Cabling Pin-out Information for T568-B 1 - 3 CCNA 1 Networking Basics v - Lab Copyright 2003 Cisco Systems Inc.
