ITU-T A.5 reference justification

These physical layers support twisted pair copper cabling only. This register is the equivalent of register 0xD3 for Lane 3 link training.

Maintains count of corrected FEC blocks on Lane 3, saturating not rolling over at 2 32 Original standard uses a single coaxial cable into which you literally tap a connection by stf into the cable to connect to the core and screen. Clause 73 specifies an Auto-Negotiation function for use over electrical backplanes. Only over Cat-6 copper cabling. General requirements and measuring methods and Amd.

Ethernet family of local area network technologies. With better channel parameters, often a longer, stable link length can be achieved.

ANSI recommends using Category 6 cable for new installations. Register 0xD3 refers to Lane 0. Most twisted 802.3zp-2007 layers use unique encoding, so most often just -T is used.

This bit is the equivalent of register 0xD1[0] for Lane 2. Now obsolete, as CAT5 cabling is the norm. F1 is encoded in bits D Updated RX Coef new, Lane 3. This was designed to leave the other two pairs free for analog telephone atd.
