currently i am using local internet cable which directly goes into the lan port of my pc. now in my building, tata indicom also provides net through that same line. so i would like to know is it possible to use both the connections through same cable? i wanted to use the local cable for my desktop and wanted to configure the tata indicom on my router. i asked the net guy and he said its possible, i needed to buy a switch. can anyone shed some info on this matter regarding whats a switch and is it possible through that? my last option would be to buy another cat5 cable and use the tata connection through that but cabling would be a lot of pain.
