I have consulted a number of references (Cisco Press books, CCO, exam guides) and some descriptions are vague while others are outright contradictory. What is the duplex rating for 100Base-T4 and what category of cable does it require. I understand that it requires 4 pair (rather than 2 like -TX) and the 100 in 100Base means 100Mbps. My understanding is that it is capable of full duplex and works over cat 3, 4, and 5. Also, has this specification been revised recently? If so is there one correct answer for production and another for Cisco CCNP exams?
