You cannot terminate two DSL modems together, you need a DSLAM on the other end of your DSL line. Instead DSL providers offer IP VPN -- which is a type of DSL connection without internet access, but for connecting several branch offices at low cost. This typically costs no more than a regular DSL connection. Think of it as poor man's MPLS cloud. Airtel offers IP VPN. Or ask your telco operator for a leased line, and get them to loop it at the exchange. This works only if both your end points are at the same telephone exchange. What you end up getting is essentially a private copper connection. You can then use any leased line modem and get up to 16Mb/s speeds. BSN offers this setup, but don't tell them you are using 16Mb/s modems! There are 3rd party providers in Chennai (assuming you're in Chennai) who can provide you point-to-point multi-mode fiber connectivity. You can terminate both ends on to a suitable GBIC module and port on a Ethernet switch. Since this is private fiber, you can run up to 10Gb/s on this link. I've never used these myself, so no first hand experience to talk about. Note that you cannot run your own cables through public property without a telco or ISP license. Therefore any suggestions on running your own Ethernet/serial/etc cable, is legal only if it's within your own private property or campus. - Raja _______________________________________________ To unsubscribe, email [email protected] with "unsubscribe <password> <address>" in the subject or body of the message. http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
