1. The 10BASET data cable requires a minimum of two twisted pairs
(transmit pair and a receive pair). The type wire used should conform
to the AT&T D-inside wire (DWI & PDS), or IBM Type 3, or Category
3 or 5 data grade or equivalent specifications.
2. The maximum length of a 10BASET data cable can not exceed 328
feet (100 meters). Typically to increase the distance each DNH will
connect to a hub or other type of repeater/medium converter.
3. The cable should be terminated at both ends with RJ-45 STP male
connectors. The table below shows the RJ-45 wiring connections for
the DNH end of the cable.
