is it possible (and officially supported) do implement "cable sharing" to use ONE (8 wire, 4 pairs) cable to connect Ethernet (using 4 wire, 2 pairs, 100MB only) and IDSN (using the other 4 wire, 2 pairs) at the same time using a unshielded CAT5 cable (~60 ft, UTP).
There are many contradictory statements which can be found in the web
- some Manufactures offering cable sharing adapters exactly for this purpose say 'yes'
- some administrator forums warn of that and say 'never do' (because of NEXT problems)
So whats the official conclusion ?
Where can I find links that prove that ?
Thanks in advance and have a happy new year !
