1. EIA/TIA-568 or EIA-TIA-568 TSB-36 compliant.
2. Cisco does not supply Category 5 UTP RJ-45 cables. However, they are available commercially.
3. Data Terminal Equipment (DTE to DTE), see
4. DTE to Repeater to DTE, see
5. 4B/5B encoding or block coding, encodes four data bits into a 5-bit transmission sequence.
