Is there a limit to LocalTalk network length?
Yes. LocalTalk networks constructed with Apple-proprietary cables can only be up to 1000 feet (about 305 metres) in length. With repeaters, this can be extended to the length allowed by the repeater (which varies). If you use PhoneNet in a trunk configuration with 22 AWG wire, you can make a LocalTalk network up to 4000 feet (1220 metres), and with standard modular phone cord, you can make one up to 2000 feet (610 metres). Again, this can be extended if necessary with repeater devices.
