OK, then I stand corrected regarding the 1GB. But I never said that I was quite sure, so I don't feel that I have made a complete fool out of myself.

Fine though that you can confirm my statements regarding 100MB (and 10MB) connections.

>Oops, you're right. Just now got a link with nfo :
>"1000Base-TX standard for using 4-pair CAT5 or CAT5e UTP (unshielded twisted pair) cable.
>Gigabit Ethernet now can run on the same Category 5 Cable or better (Cat5e, Cat6, etc) twisted pair cables with the same RJ45 connectors that are used in 10/100Mbps networks. If your cables are good for 100Base-TX, they should work for Gigabit Ethernet.
>Note: Gigabit Ethernet over copper requires all 8 wires to acheive its bandwidth so you must use all four pairs of the ethernet cable. "
>Funny all others I read up to date were saying it has something more to do with twists count. I have to read the TIA standard once again when Gb arrives :(

>>Hi Tore,

>>The spec for 1000BT calls for all 4 pair - I thought you might have something else in use that got you around that. Off the shelf equipment needs 4 pair. I am surprised that you have no problems at 100 Mb splitting out pairs. Your luck is better than mine :-)

>>>PLease forgive me if I am wrong, I have many computers and a mix of 100MB and 1GB. The 100MB I can positively confirm, about the 1GB I am not quite sure, but I belive it also only 2 pair? I must confess that where I have the mix of lan and PABX on the same cable, I only use 100MB. But at my office I have some offices where I needed more connections than I had prepared for, so I have splitted one connection into two, by using 2 pairs for connection one, and 2 pairs for the other connection.
>>>I am almost sure I also get 1GB connection speed in those cases, but I am not willing to bet, I may be wrong.
