I need to extend a LAN connection by about 300 feet from one building to another. CAT5 or similar cabling is not feasible but phone lines already are in place. Does anyone know if you can connect 2 DSL modems together that would transmit data between two building? Will they communicate with each other? I have several B90 Westell DSL modems sitting around that I could use if anyone has any suggestions about this possibility.

Well you could use a phoneline network which could get you aprox. 11Mbps if you have the line already running for that. However I myself would probably go for the hammer drill, jack hammer and ditchwitch =o)(You will also need some conduit, concrete and or asphault.) and use one of the following most likely 100BASE-Tx or fiber unless the distance is needed for 10BASE5 You could however if in the budget get seperate access in the other building and create a WAN instead of a LAN. Here are some length specs: 10BASE5 (10 Mbit/s, baseband, 500-metre segment limit) - this is the original type of ethernet and uses a large-diameter coaxial cable; it is therefore colloquially known as thick-wire ethernet. 10BASE5 is not recommended for new installations. 10BASE2 (10 Mbit/s, baseband, 185-metre segment limit) - this uses a thinner and cheaper coaxial cable and is therefore known colloquially as thin-wire ethernet or, sometimes, cheapernet. 10BASE2 is not, in general, recommended for new installations but, in some instances, it may be sensible, e.g. for extending an existing installation or for linking between repeaters within a single building where the distance is too great for a 10BASE-T inter-repeater link. 10BASE-T (10 Mbit/s, baseband, twisted-pair) - this is colloquially known as twisted-pair ethernet and is the recommended local area network technology for new installations. It supports a segment length of 100 metres of which 90 metres should normally be allowed for fixed wiring and 10 metres for fly-leads. 10BASE-F (10 Mbit/s, baseband, fibre-optic) - at the time of writing, an amendment, numbered 14, to the ISO/IEC 8802-3 CSMA/CD standard is in an advanced state of development and the current standard only provides for fibre-optic inter-repeater links (FOIRL). FOIRLs are needed for inter-linking repeaters over distances that are greater than the 100 metres allowed by 10BASE-T (or 185 metres of 10BASE2), for links between buildings, or for links between different equipotential earth zones. http://www.netmasters.com
