Hey, I have numerous computers in a business atmosphere, all of which are replica models of each other. Unfortuantly, broadband is not available in our area and we are restricted to dial up connection. However, the facility already has all of the central wiring into hubs and I know that if I were to add a router, I could just use it for the network. However, I can not find such a thing as a dial-up router. Is there such a creature? For the ammount of internet use we are going to use, broadband isn't really a must...

Sure. It used to be very common. Here is a example. Router vendors like Cisco support external modem connections as well, if not modular modem add-ons (these are much more expensive than the 3com one).

The SMC Barricade 7004 series of routers has a serial port that can be used for fallover dialup. I have used it for as an internet connection with an external modem only dialout. My only problem was configuring disconnect when not in use.

You can buy a router capable of sharing a dial-up connection, and you can also use a junker computer with a modem to perform ICS. You might also want to look into ISDN service in your area.
