Abstract: The present invention describes an automatic calibration method for a measuring circuit for example in an industrial automation or handling process, where only one person is needed to manage the entire procedure. The components are a calibrator (11) which the worker in the field has with him, which can be connected to the starting end of the measuring circuit in order to give an impulse. The quantity to be measured/calibrated has not been limited. The measurement result is seen at the end of the measuring circuit on a screen of the control room, i.e. DCS (13). Depending on the alternative embodiment, the measured numerical value can be steered either to a dedicated server (14) over an OPC connection, and onwards wirelessly or via Ethernet back to the calibrator (11). One alternative is to use a smart device (16) which the worker has, with suitable applications, to which the measured data can be sent over a network, and the data is also presentable in a user-friendly manner in such an application.

Abstract: A telecommunications switch is provided with an internal ethernet link which is connected to a group switch/time switch portion of the switch through a number of interface processors. The group switch/time switch portion functions to switch data communications among and between the subscriber lines, trunk lines and the interface processors. The ethernet link serves as a concentrator for packet data communications carried over the subscriber/trunk lines and handled by switch. The interface processors operate to selectively insert and extract packet data communications to and from the ethernet link. A connection is made via the ethernet link to an Internet access point to allow concentrated data packet communication with the Internet.
