I am setting up a T-1 circuit and the instructions for the WIC on the router request that I use a RJ48C cable. I do not have one. Can I get away using a normal RJ45 Cat5e cable?

Who are the top five ip telephony integrators in the Boston area?

If I subnet my network can the hosts share the same gateway? For example can they use a gateway that is not on their subnet, or do I need to add a gateway for each of the subnets.

Currently I have a class C network that is attached to the internet. I would like to keep my current setup, but extend the class C over a private network to another location. In the end there would be two class C's sharing the same internet connect...

If I was going to break down a class C using a subnet mask of 255.255.255.224 would I lose the first and last subnet? A lot of what I have read says a I would, but is that completely true or is there a work around?
