    I do have a question

    The exchange needs to switch for you to connect to exchanges from exchanges

    Why cant there be a simpler method so that there's no need to switch

    A direct connect method perhaps?

    This would be the same as networking two computers together with a cable. The only computers you would be able to access would be those two - and no others.

    Switches allow your computer, and telephone, to talk to millions of computers rather than just one.

    If you request a web page from an international site - say one in the UK - you can use the "tracert" command to see which computers the request goes through. Several computers will show in the trace.

    Doing the same tracert at different times of the day may show a different route.

    The actual telephone lines it goes through will be a mixture of copper wires, fibre optic, satellite etc.

    Leaving NZ it will either go through a submarine cable to Australia or via satellite at somewhere like the Warkworth site depending on conjestion on the network. From there it will bounce along using a mix of cables and satellites.

    If you ever go through Warkworth take the turnoff to the satellite site. They have an interactive info room with demos.

    A Telephone Exchange is a Central Office . They usually have one for each town/area.
    If you use dial up, you connect thru your telephone line (land line) to YOUR ISP. (Internet service provider’s modem)
    If You use broadband this is taken from your house via copper or fiber. This goes to the central office and is hard wired to your ISP’s port. The speed is govern red by your ISP and not the Telco or central office.

    Not quite. The ISP will set the maximum speed you can download at - all things being equal.

    The available maximum speed is set by the telecommunications hardware - cables, switches etc

    The physical telephone system creates the inequality. eg me being rural and 5km from the exchange means I can never get the maximum speed that is available elsewhere.

    The exchange, apart from acting as a central point, also does other things, like caller ID, voice mail and so on. The equipment in it is not just a big patch panel.

    Thats why we have exchanges.
