dc.description	Mobile telecommunications service providers operate numerous geographically dispersed remote sites for the purpose of increasing network coverage and enhancing signal quality in order to deliver acceptable quality voice, data and internet services to their subscribers. It is not practical to have all these sites manned by maintenance personnel. In order to improve reliability, it is the norm to provide built in redundancies in these remote sites so that failure of primary equipment results in handover of function to similar secondary equipment. This is normally implemented in the transmission equipment, servers, power and environmental control equipment such as air conditioners. The most common sources of failure in telecommunications facilities in the remote sites are power failure, environmental control failures and security breaches. Monitoring of these conditions is achieved by use of appropriate sensors to detect failure and/or breaches. Information from these sensors is ferried together with voice and data traffic as an overhead to a central network operation Centre (NOC). The NOC is manned round the clock to ensure conditions at remote sites are monitored and failure information relayed to field maintenance staff through calls and short messages. The quality and availability of telecommunications service is monitored by communication regulators in most countries and is subjected to service level agreements by customers. Both these situations can be very costly to service providers if violated.Recovery at remote telecommunication sites is a race against time. In order to attain quick turnaround during failure, alarm information must reach the field maintenance staff within the shortest time possible. Alarm routing through the NOC normally faces avoidable delays. vi In this research, an overlay monitoring network is designed to monitor alarm information at remote telecommunications sites and relay the same directly to the field response staff. This overlay network is designed as an artifact using a sensor network and a micro controller as the intelligent device. Alarm information is relayed to relevant response teams directly through the use of text messages. Where total telecommunications failure may affect network to the GSM unit in the artifact, a SIM card for a different operator can be used instead.
