Appendix C: UTP Cabling
This appendix discusses various aspects of connection media. The performance of an AutoView
3050/3100/3200 switching system depends on high quality connections. Poor quality or poorly
installed or maintained cabling can diminish AutoView 3050/3100/3200 system performance.
AutoView 3050/3100/3200 switching systems utilize UTP cabling.
NOTE: This appendix is for information purposes only. Please consult with your local code officials and/or
cabling consultants prior to any installation.
UTP copper cabling
The following are basic definitions for the three types of UTP cabling that the AutoView 3050/
3100/3200 switch supports:
• UTP (4-pair) high performance cable consists of twisted pair conductors, used primarily for
data transmission. The twisting of the pairs gives this cable some immunity from the
infiltration of unwanted interference. UTP cable is generally used for networks running at 10
or 100 Mbps.
• CAT 5E (enhanced) cable has the same characteristics as CAT 5, but is manufactured to
somewhat more stringent standards.
• CAT 6 cable is manufactured to tighter requirements than CAT 5E cable. CAT 6 has higher
measured frequency ranges and significantly better performance requirements than CAT 5E
cable at the same frequencies.
Wiring standards
There are two supported wiring standards for 8-conductor (4-pair) RJ-45 terminated UTP cable:
EIA/TIA 568A and B. These standards apply to installations utilizing CAT 5, 5E and 6 cable
specifications. The AutoView 3050/3100/3200 switching system supports either of these wiring
standards. Table C.1 describes the standards for each pin.
