Cabling
For complete rules of cabling and for information useful in
planning network configurations, see ISO/IEEE Publication
8802-3. The AT-1700T is for use with 10BASE-T segments, using
an 8-wire (4-pair) RJ45 jack for the network cable, shown in
Figure 1.

Important 10BASE-T Cable Considerations
A serious problem exists concerning identification of modular
cable. There are various grades of voice-quality and data-quality
cables available. These can appear to be similar externally, and
their DC characteristics are also similar, although their AC
characteristics, and therefore high-speed data transmission
characteristics, are radically different.
