A method and apparatus for a computer and telecommunication network which can receive, send and manage information from or to a subscriber of the network, based on the subscriber’s configuration. The line-to-line distance when the first and second signal lines SL1 and SL2 are disposed in parallel is shorter than the line-to-line distance when the third and fourth signal lines SL3 and SL4 are disposed in parallel. The heat source loop may also include a heat storage medium to allow continuous operation even when the source of heat is intermittent.
