The convergence of telecommunications and computers has expanded the role of telecommunication facilities in all human activities. Constant availability of these facilities is dependent largely on formidable effective maintenance policy in the telecommunication industry with a view to developing a policy that will ensure maximum efficiency of utilization and growth of telecommunication infrastructure in Nigeria. In this paper, the data were collected with the aid of questionnaires and interview guide were analyzed accordingly using descriptive statistics, while three hypotheses were tested using chisquare to determine the relationship between maintenance on both effect of external factor and policy effect. The result revealed that observed value using 0.05 level of significant is 9.488 and chi-square calculated is 197.1 and 105.91 for both external factor effects and effect of policies on maintenance respectively. This actually showed that external factors and effect of policies have significant effect on maintenance. Also, from the table obtained, it was concluded that there was not significant different in faults in the sites. The result indicated that existing telecommunication were poorly maintained and overstretched. Appropriate strategy that could be incorporated into a comprehensive policy on manpower training, pre-start up and post-start up documentation, funding organization, proper coordination and harmonization of the activities of the government agencies and proper education for technicians/engineers involved in maintenance activities were proffered.
