2.2CABLE RECOMMENDATIONS/TROUBLESHOOTING

The following sections describe common cable problems and recommendations for correcting them.

Crosstalk

Crosstalk is interference caused by signal coupling between the different cable pairs contained within a multi-pair cable bundle. Multi-pair cables should not be used for UTP lobe cabling. UTP lobe cabling should be dedicated to carrying token ring traffic. Avoid mixing token ring signals with other applications (voice, etc.) within the same cable.

Noise

Noise can be caused by either crosstalk or externally induced impulses. If noise induced errors are suspected, it may be necessary to reroute cabling away from potential noise sources (motors, switching equipment, fluorescent lighting, high amperage equipment), or to ensure that the electrical wiring in the area is properly wired and grounded.

Temperature

The attenuation of PVC insulated cable varies significantly with temperature. Plenum-rated cables are strongly recommended at temperatures greater than 40˚C to ensure that cable attenuation remains within specification. Check the cable manufacturer’s specifications.

In addition to complying with the preceding cable specifications, the following recommendations should be followed to minimize errors and help to obtain optimum performance from your network:

UTP cabling should be free of splices, stubs or bridged taps.

No more than two punch-down blocks between TCU ports and wall outlets.

Metal troughs, ducts, etc. carrying token ring signals should be properly grounded.
