I need to connect a computer at a distance of about 2km(along an existing line) with a LAN(Intranet) for the purpose of accessing database files on the LAN. An existing telephone line ckt for the distance (with or without an EPABX in between) is available. The LAN runs Windows Server 2003 and Windows XP.

Hitherto I was planning to connect it using DSL modems at either end. However I found from one of the dicussions on the forum that it would not work.

Please advise me as to what sort of hardware and software would be required to establish the connection to the LAN(intranet):- The constraint being the media (Cu line) in between.
