Fault Tracing ASB 150 02

## General

These fault locating instructions shall serve as a guide for servicing an ASB 150 02 telephone exchange (PBX). This document presupposes that all installation and start-of-operation instructions have been adhered to. This document covers only such faults (errors) as equipment malfunctions or some incorrect programming. When beginning start by classifying the fault type (see Fault locating).

Generally, when servicing a PBX a hardware fault can only be remedied by replacing the faulty hardware on site and the faulty unit(s) are to be returned to the supplier with a claim for compensation. No repairs are to be done in the field.

The PBX has operation and maintenance programs installed which can be accessed via the PC-program RASC and Cordless System Manager software (CSM). These programs run on a PC that can be situated either in a remote service centre or locally next to the PBX.

The service personnel shall be familiar with the system, in particular regarding RASC and CSM with their possibilities, as RASC and CSM are the best fault locating aids.
