Abstract: A method and system for transparent file proxying allows an intelligent storage appliance (ISA) that connects a remote computer connected to a local area network (LAN) through a wide area network (WAN) to locally provide to the remote computer files that would otherwise be obtained from a computing device connected to the LAN over the WAN. Based upon policies that include user policies, group policies and corporate policies, selected files are transferred (or mirrored) from the computing devices connected to the LAN to the ISA. When the remote computer desires to access a file, the ISA intercepts and analyzes the file request. If the ISA determines that the requested file is one that is locally stored on the ISA, the ISA intercepts and services the request locally (thereby preventing the request from traversing the WAN), and transparently proxies the selected file to the remote computer. A user of the remote computer views the file, unaware that the file is locally provided by the ISA.

Abstract: For single line telephone service, let red/green denote a pair that is connected to the central office, and yellow/black denote an unused pair, but which also appears at the connections to the subscribers equipment. Any computer or other device that is to be interruptible by an ordinary handset is connected to red/green through a phone service re-allocation circuit that is also connected to, and that monitors, yellow/black. An extension allowed to cause an interrupt is connected to yellow/black. For RJ-11 connections an adapter routes the yellow/black (in the wall) over to the terminals normally used for red/green. An off hook condition of the interrupting equipment connected to the adapter now serves as part of a signal to the re-allocation circuit. Upon a signal, the re-allocation circuit terminates the access of the interruptible equipment to the red/green pair, and bridges the red/green pair to the yellow/black pair instead.
