    I made a hard research about it. However, I truly couldn't get a clear result. I really do wanna learn whether routers are different than modems while accessing the Internet. In houses, there are devices produced DSL modem/router to feature as both of them. But in enterprises, SOHOs , is the situation different ?


    In enterprises, are routers sufficient while accessing the Internet for employees inside the enterprise?(especially
    doing VPN between sites)

    which type of routers act also like a modem if Internet is the case?

    did you really research it that hard? You can read all about modems here http://en.wikipedia.org/wiki/Modem

    The dsl or cable routers that one gets from an ISP are really multi-layer multi-function devices. You could also stick a DSL WIC in a cisco router - you can read about that here: http://www.cisco.com/en/US/prod/col...0aecd8028aa5a_ps5853_Products_Data_Sheet.html

    Surely you learned a little bit about WAN technologies/the internet - frame relay/T1/vpn in your studies for the CCNA.

    i know that modems are used mainly for telephone lines. But routers?

    so what is the answer for enterprises? routers built-IN WICs?

    Main part of that page that applies: http://en.wikipedia.org/wiki/Modem#Broadband

    .. I just wrote a line and thought.. "seriously?", anyway...

    If an enterprise is using an analog connection to connect their LAN to the "internet" (and yes ADSL is a form of analog, just highly complex) then a modem would be needed - also of course the modem provides the authentication with the ISP on the other end.

    And for Fiber Optic connections, Google's service sums it up very well: http://www.google.com/tisp/install.html

    I still see one problem on the horizon: I have two palms, but only one face.

    EDIT: I will attempt to give a more constructive answer: This is why we recommend getting real-world experience before pursuing the CCNA.

    More likely though, is you will connect your router to their router using ethernet. Their router will have a circuit coming into your building, but this can be presented many different ways.

    Uuuhhh, guys, we all know kobem but it does no-one any good if everyone just gives smart@rse replies instead of just passing it over.

    To be fair mate, we've tried giving constructive advice, we've even tried being blatantly direct. Neither worked....

    Why even bother replying then?

    Why do people even choose to enter threads when they see they are created by him?

    I always find it funny when people wade in to decry posting in threads when there is no point. Especially since I see the very same people doing similar things elsewhere... Funny that.

    I tried that in the past. Unfortunately it doesnt do the one thing I would want it to do - remove threads started by them from the new posts listing. Its a shame really, otherwise it would be a brilliant feature. I've used it once or twice though, even without that.

    All i'm saying, is if his posts annoy you, why enter the thread in the first place? I don't get it.
