在网线长度小于100米时，Gigabit Ethernet 用cat5e与cat6区别不大。如果只在独立屋内布网，Gigabit switch/rouyer放地下室， 那么每根线的长度不会大于100米。
正如sip说的，cat5,cat5e,cat6,cat6a,cat7,cat7a网线都只用4根线。

The 8 Position 8 Contact (8P8C, also backronymed as 8 position 8 conductor; it is often incorrectly called RJ45)[1] plugs and sockets are most regularly used as an Ethernet connector.[2] 8P8C connectors are typically used to terminate twisted pair cable.
8P8C are commonly used in computer networking, where the plug on each end is an 8P8C modular plug wired according to a TIA/EIA standard. These cables are typically used to connect Ethernet or Token Ring network interfaces. Most network communications today are carried over Category 5e or Category 6 cable with an 8P8C modular plug crimped on each end.
The 8P8C modular connector is also used for RS-232 serial interfaces according to the EIA/TIA-561 standard[1]. This application is commonly used as a console interface on network equipment such as switches and routers. Other applications include other networking services such as ISDN and T1.
In floodwired [3] environments the center (blue) pair is often used to carry telephony signals. Where so wired, the physical layout of the 8P8C modular jack allows for the insertion of an RJ11 plug in the center of the socket, provided the RJ11 plug is wired in true compliance with the U.S. telephony standards (RJ11) using the center pair. The formal approach to connect telephony equipment is the insertion of a type-approved converter.
The remaining (brown) pair is increasingly used for Power over Ethernet (PoE). Legacy equipment may use just this pair; this conflicts with other equipment as manufacturers used to short circuit unused pairs to reduce signal crosstalk. Some routers/bridges/switches can be powered by the unused 4 lines — blues (+) and browns (−) — to carry current to the unit. There is now a standardized scheme for Power over Ethernet.
Different manufacturers of 8P8C modular jacks arrange for the pins of the 8P8C modular connector socket to be linked to wire connectors (often IDC type terminals) that are in a different physical arrangement from that of other manufacturers: Thus, for example, if a technician is in the habit of connecting the white/orange wire to the "bottom right hand" IDC terminal, which links it to 8P8C modular connector pin 1, in jacks made by other manufacturers this terminal may instead connect to 8P8C modular connector pin 2 (or any other pin).

... GE requires 250MHz bandwidth (4 pairs)
FE only needs 100MHz bandwidth (2 pairs)
Where do you get extra bandwidth if you always only used 2 pairs?!?!
GE requires all 8 wires. Even if the "connected speed" says 1000 with 2 pairs, that's only the highest common denominator (both capable). But actual wire speed is reduced.
You can MAYBE modulate voice along with ethernet. But what's the point... DSL is a NONO for sure. Even running DSL/FE on the same CAT6 is doubtful, because of the possible noise components

太固执了。
他可能是不太明白。
ＰＬＡ，follow these steps:
１到你的basement的接线板，看电话线都接到哪两根cat5e中的线了，通常是蓝色的和蓝花的。
２到homedepot 买几个电话线加ethernet网的接线盒，双口的，取代你现有的电话单口接线盒，需要几个
买几个。
３把那两根电话线，还接到电话插头上，剩下的１，２，３，６接到你的ethernet接头上。这样，每个屋
子都有电话和以太网接头了。
如果你的路由器（router,/switch)在basement, 就可以直接连接到每个房间的cable上。Homedepot有卖
这样的带socket的接线板。如果是从一个房间到另一个房间，只要找出相应的cable,把对应的４根线连起
来，就行了。
