Abstract: Measurements and analyses of telephone in public switches in Calabar were undertaken in Nigerian Telecommunications Limited (NITEL), Calabar exchange. Data collected from 6 routes were analysed. Results show that the answer-bid ratio for the routes was in the range 9.70-47.40, answer-seizure ratio, 10.10-47.80 and call completion ratio, 77.70-100. This means that not up to half the number of calls were effectively carried, thereby implying poor performance compared to international evaluation indices.
