Abstract:
Web Based Cable Connectivity Monitoring System was the title of the project chosen to develop for Sri Lanka Telecom PLC in my partial fulfillment of the requirement of the degree of M.sc in Information Technology of the University of Moratuwa.
Sri Lanka Telecom is the owner of the largest copper network in Sri Lanka which spans all over the island. Variety of services such as PSTN Voice Calls, ADSL Broadband Connections, IP-TV connections, Leased Line Connections uses this copper network as the communication media. So it is important to keep a track of this copper network, especially trunk cables which contain large number of wire pairs in order to provide uninterrupted and satisfactory service to subscribers. Currently there is no online monitoring system for this. SLT was seeking for a proper system to monitoring disconnected or damaged cables for last few years because it is so important to identify those disconnected cables as soon as possible and rectify them. Also Sri Lanka Telecom has to take rapid reactions to avoid stealing of these expensive cables.
Therefore, under this project, monitoring trunk cable disconnections from a remote location by using an embedded system which contains Rabbit Core RCM 4010 microprocessor module and SNMP technology was proposed. This unit will send disconnected cable information with its position or segment using SNMP trap messages through Ethernet to SNMP trap detection unit which will be in a central location. And this will acknowledge the authorized persons in few seconds via email. This system also reduces the number of points have to be checked and makes easy to locate the fault. This system will detect, display & record cable disconnections with other features such as fault localization & security.
This will reduce time taken to report cable faults and rectify them which will make a direct impact on customer satisfaction. And also will increase revenue of Sri Lanka Telecom by effectively using manpower.
