My ISP has installed Ethernet/Internet service at my office (3Mbps up/3Mbps down). The provider calls it "3M EIA service". This replaces a DSL connection. My office never has more than 15 PCs accessing the Internet at a time.
Already installed is a Cisco WS-C2950G-48-EI 48-Port Catalyst 2950 Series Switch. I also have available a Cisco 96-Port Catalyst 4000 Series (Model: WS-C4003 Series) hand-me-down that I can install if the 2950 won't work. I've been told that both will work.
I also have available to me a Cisco 1841 router (also a hand-me-down) with a T1 module which I can replace with an appropriate module. However, I've been told that any Cisco 1800 series router won't work. The 1900 series will (expensive for me).
I have never had to connect, configure or otherwise deal with such a circuit. I am very much a newbie to this so I beg your indulgence.
What I need to know is what do I need by way of hardware (router? or other) in order to make this work? Would a D-Link router, e.g., DIR-655 suffice? I really don't need wireless.
Unfortunately, I am on an extremely tight budget (I may have to pay for this out of my own pocket). When I Google for answers, all I get is something from Cisco. While Cisco may be the obvious answer, their solutions are expensive unless they sell suitable hardware at a lower cost. If there are any alternatives, I would like to know.
