## Tools for fault locating

Fault locating from an operation and maintenance (O&M) centre requires a PC with RASC and CSM installed and a Hayes-compatible V.32bis modem.

Fault locating on site requires a (portable) PC with RASC and a V.24-cable connected to a free V.24-port. Additionally required tools are: a voltmeter (DVM), a system telephone, board extractor and a set of screwdrivers. As the boards are sensitive to electrostatic discharges please use a grounding wrist strap correctly connected to ground when handling the boards.

The Cordless System Manager software contains functions for Cordless System part regarding initialization, system maintenance and updating, system fault finding and repair. As RASC cannot detect IC-LU boards installed in the system it is advisable to locate these boards to the right of the IC-CU_ board.

The Cordless System Statistics is an extension to the Cordless System Manager. It collects and interprets statistical information from the Cordless System. It gives an overview of the traffic load of the total Cordless System, load per Base Station or per portable telephone. Important data of telephone calls are stored, for example the duration of calls, the number of hand over and errors like failed calls or portable telephones that could not be reached.

The Cordless System Manager software has a menu driven user interface. Separate text files permit you to translate and obtain the menus in the desired language.
