Lines: 17 Nope, 3000-4000 miles is probably about right. The telephone company isn't a whole lot better aid out than the roads. You first have to make it from your house to the central office (probably 3-5 miles in most places). Then from there you have to go to the toll office where your long distance carrier has its point of presence. This may be halfway across the LATA in the wrong way. For example, our data circuits from north of Princeton run to Hamilton Square (which is precisely in the wrong direction) on their way north. Once you get into the long distance carrier system, you still get routed all over creation. A bit over a year ago a trunk cable was dug up in Oakland. This took out a large portion of the ARPANet. An interesting picture was the map of the ARPANet with the trunks shown as straight lines between the nodes they were connecting. Links that were interrupted as a result of the hole in Oakland were highlighted in blue. It was amazing how many points that aren't anywhere near California were affected. -Ron
