N o t e
A 100VG LAN complies with the IEEE 802.12 standard and supports
category 3, 4, and 5 four-pair, 100 ohm UTP (unshielded twisted-pair) cables.
Category 3 UTP cable is standard, voice-grade, telephone cable. For more
detailed information on supported LAN cables, refer to the included 100VG
AnyLAN Technology Guide and appendix A.
If you presently have a twisted-pair cable network that complies with
Ethernet/IEEE 802.3 Type 10Base-T specifications, generally you can use the
same cables on your 100VG network. Note, though that the 100VG network
technology uses all 4 pairs of the UTP cable, while 10Base-T uses only 2
pairs. Make sure that all 4 pairs are wired correctly. See the included
100VG AnyLAN Technology Guide and appendix A.
To connect end nodes, you can use unbundled or bundled cables. An
"unbundled cable" refers to one that contains only four twisted pairs and is
used to connect a single end node or device. A "bundled cable" refers to a
cable that contains 25 or more twisted-pairs in one sheath and is used to
provide a convenient method of connecting multiple end nodes.
