Abstract: A method for analysing performance of a media recording system in a telecommunications network comprising the steps of selecting an extension within a telecommunications network, the extension capable of exchanging communication media, designating a time period within which communication records for the extension should be analysed, receiving communications data for the network extension, the communications data comprising data associated with communications involving the extension with the time period, receiving media data for the network extension, the media data comprising data associated with recorded media content of communications involving the extension within the time period, comparing the communications data with the media data to determine the performance of the communications recording system.

Abstract: A support structure for a tool comprising a boom or arm for supporting the tool, a pendulum pivot supporting the tool with respect to the boom or arm in a manner which allows the tool to pendulate and self monitoring and operating dampening means for controlling the pendulation of the tool on the pendulum pivot with respect to the boom or arm.

Abstract: A rotatable cutting tool with a shank for locating the rotatable cutting tool on a work face, a body and a hard tip wherein said body is of a generally tapered shape and has at least one flight wherein said at least one flight extends longitudinally and at least partially around the body whereby movement of the rotatable cutting tool through a substrate urges the tool to rotate.
