hello,i am installing cat 5 cables for 3 seperate office networks , the cables are brough to an hub in each office,if i want to provide for joining the networks at a later stage is it sufficient to run a cat5 cable from hub1 to hub2 to hub3 ,i merely want to provide in case the networks becomes at a later stage ,thanks

the last bit should be in case the 3 networks become one later
