What's the maximum end-to-end distance a PhoneNet network can be, and what factors does this length depend on? Paul DuBois dubois@primate.wisc.edu

(This is from memory.) The total bus length limit is around 3000 feet, but this assumes a particular wire gauge that I don't recall. You might just go buy one connector kit and read their manual. It is a pretty good intro to Mac networking and PhoneNet connector use. One thing I would definitely recommend is that you know exactly where your wiring goes when you set your network up. Some older buildings are not wired so that you can use existing phone cabling to connect the network. You can extended the total length of your network with repeaters and starcontrollers. Lots of things cut down on the total length of the network. Using LocalTalk connectors, mixing wire types, extended runs with modular wire (the kind you use to hook the phone to the wall jack.) - Allen

The Farallon PhoneNET Connector User's Guide is one of the finest and most useful pieces of technical writing I've ever seen, bar none. Their "conservative guidelines" for normal LocalTalk speeds are as follows: Topology 22 gauge 24 gauge 26 gauge Max # Nodes daisy chain n/a n/a 1800 ft 24 backbone 4500 ft 3000 ft 1800 ft 48 3-branch passive star 1500 ft 1000 ft 600 ft 16 (each branch) 4-branch passive star 1125 ft 750 ft 450 ft 12 (each branch)
