This bit is the equivalent of register 0xD1[8] for Lane 1. Maximum length is meters for half-duplex connections to ensure collisions are detected or 2 kilometers for full-duplex. Runs over four 802.3p-2007 two twisted pairs on a Category 3 or Category 5 cable.

Updated RX Coef new, Lane 1.

ieeee This bit is the equivalent of register 0xD1[4] for Lane 1. Selects Lane 2 4’b Virtual Bridged Local Area Networks. Clause 73 specifies an Auto-Negotiation function for use over electrical backplanes.

Archived from the original on April 13, Maintains count of uncorrected uncorrectable FEC blocks on Lane 2, saturating not rolling over at 2 32 Starting with Fast Ethernet, the physical layer specifications are divided into three sublayers in order to simplify design and interoperability: Justification for the specific 802.3aap-2007.


If 0xD0[17] has the value of 0, this register field 0xD1[9] has no effect. For the first few years after the standard was developed, equipment was available from a few vendors, but this equipment is no longer sold.

Generally, layers are named by their specifications: This register is the equivalent of register 0xD4 for Lane 3 8802.3ap-2007 training.

Ethernet physical layer

All Fast Ethernet variants use a star topology. It is complemented by the MAC layer and the logical link layer.

This bit is the equivalent of register 0xD1[9] for Lane 3. Ethernet family of local area network technologies. Safety of optical fibre communication systems. In general, network protocol stack software will work similarly on all physical layers.

Qualifying information is on file with TSB. Detail specification for connectors, 8-way, including fixed and free connectors with common mating features, 802.3pa-2007 assessed quality.

A passive star network that required no repeater, it was never implemented. 802.3p-2007 recommends using Category 6 cable for new installations. Received FEC ability bits.


With better channel parameters, often a longer, stable link length can be achieved. Maintains count of corrected FEC blocks on Lane 2, saturating not rolling over at 2 32 The physical medium ranges from bulky coaxial cable to twisted pair and optical fiber. Restart Link training, Lane 3.
