3bp, IEEE Draft Standard for Ethernet Amendment: Physical Layer Specifications and Management Parameters for 1 Gb/s Operation over a Single Twisted Pair Copper Cable, defines physical layer (PHY) specifications (including optional single- pair autonegotiation
and Energy Efficient Ethernet) and parameters for full-duplex 1 Gb/s Ethernet operating in harsh environments found in automotive and industrial applications.
3 Working Group adopt its autonegotiation
technology, referred to as "NWay," into the Fast Ethernet standard.
It features one 10/100/1000-Ethernet port operating in autonegotiation
mode for seamlessly adapting to Ethernet infrastructures, and supports all relevant encryption methods, including WPA and WPA2.
The TC3240 provides 10/100-Mbps autonegotiation
and automatically adapts to full- or half-duplex mode.
The four Ethernet ports support autonegotiation
, allowing connections with half and full duplex, 10 and 100 BaseT devices plus auto MDX, eliminating the need for crossover cables.
rate adaptation feature ensures ease of use, as it allows the Prestige 641 to automatically adapt to whatever ADSL line settings are being used.
While maintaining the autonegotiation
feature, the latest release also offers the ability to disable autonegotiation
and force the copper port to 10 Mbps or 100 Mbps, and to force both the copper and fiber ports to full or half duplex.
The adapter supports autonegotiation
for full-duplex, master/slave, automatic MDI crossover and pause flow control over the hosts SERDES and/or the Category 5 interface.
The AQ1002 is a monolithic, low-power, full-reach 10G/1G/100M PHY, which brings the benefits of twisted pair cabling and autonegotiation
to 10GE networking.
The copper port supports 10/100/1000-Mbps speeds and half or Full-duplex autonegotiation
, with both hardware and software manual override controls to set the desired speed and duplex mode.
The Services Line Card supports copper-to-fiber (R851-1S) or fiber-to-fiber (R851-SS) connectivity with 10/100/1000Mbps autonegotiation
on the copper port.
provides automatic selection of either the 10- or 100-Mbps data rate, and the MDI/MDIX feature allows the use of either straight-through or crossover electrical interface cables to simplify installation.
