Works great - because if you know what you're doing.

These two adapters are ideal if you only have one network connection in the room, but on the PC and would like to provide its the fax. Therefore one must indeed u. U. occupy the cable for the fax machine itself, because the occupation is documented but on the adapters, this is no problem with the right plugs and a crimping tool. The adapters have solved my problem in a charming way, without that I had to tinker a lot. Very nice parts.
