? Section "10BASE-T Signal Encoding", Sub-section "Physical line signaling", first paragraph |
Using balanced differential signalling, it's not the case that, "In each wire pair, one wire is used to carry the positive amplitude of the differential signal (from 0 volts to +2.5 volts), and one wire carries the negative amplitude of the signal (from 0 volts to –2.5 volts)." Rather, one wire is used to carry the signal (either +2.5 volts or -2.5 volts) and the other wire carries the inverse of the signal. The differential receiver then sums (subtracts, actually) the signals, reinforcing the signal while rejecting common mode noise. |

Printed | Page 66-67 Last paragraph on 66. First paragraph and Figure 5-1 on page 67. |
Figure 5-1 on page 67 lists two computers connected. Computer A is listed as connecting at 10Base-T but the paragraph above states that computer A is capable of 10/100. Also, according to the same paragraph, computer B only supports 1000Base-T, yet it connected at 100Base-T. If the switch, computer A and computer B all support Auto-Negotiate, then shouldn't computer A connect at 100 Mpbs and computer B at 1Gbps? |

The last sentence states "minimum of 25.50 watts". Should that be "maximum" instead? |

Its states "The standard groups the cable specifications together as 10GBASE-S for short-reach multimode and 10GBASE-S for long-reach single mode". Are they suppose to be duplicated in name or is this a typo? |
