Abstract: An adjustable guide for cutting building material with a circular saw is provided. The guide includes a base having two section with a space therebetween defining a path of travel for a circular saw blade. The guide includes a rail system having two rails, where each rail is attached to a base section. The space between the base and the rail system provides a channel for receiving one or more stacked layers of building material simultaneously.

Abstract: To measure the quality of service at the application level in a telecommunication network (N), a function (A) is provided for carrying out sessions at the application level on said network (N). Through this activation function (A), sessions are then carried out, measuring (F) and also storing (HK in a set of points (S1, . . . , Sk, Sn) of the network (N) data indicative of the behavior of said network. The possible occurrence of critical situations relating to quality of service is verified (B) and, upon the occurrence of a said critical situation, a trigger signal (Trigger) is generated. By effect of the generation of said trigger signal, the data indicative of the behavior of the network measured and stored in the aforesaid set of points of the network (N) are collected in centralized fashion (H). The data thus collected are indicative of the end-to-end quality of service of the network (N) itself. Preferential application to packet networks like mobile telephony network such as GPRS or UMTS networks.

Abstract: The present invention relates to a test plant (10) for digital mobile radio systems comprising one or more radio base stations (RBSs) (12), a corresponding base station controller (BSC) (11) and a testing apparatus (14) interposed between the RBSs (12) and the BSC (11). The test plant (10), and the testing apparatus (14) in particular, make it possible to check mobile radio system performance while allowing proprietary Operation & Maintenance messages to travel transparently between the RBSs (12) and The BSC (11), and generating, in the apparatus (14), radio protocol messages (Radio signaling Link messages) which in general constitute the portion of information on which testing is carried out and are organized in accordance with predetermined standards.
