Abstract: Performance test carried out along the Calabar-EPZ Nigeria Telecommunications Limited (NITEL) Digital Exchange Route shows good agreement of signal strength. The result also shows that the route is in a very good condition. It also shows that voice transmission along this route has good voice clarity with a Bit Error Rate (BER) in order of 10-3 which requires a Signal to Noise Ratio (SNR) of about 16 dB to achieve the error performance level. The route has a bandwidth of about 34 MHz, which makes transmission faster along this route and makes it easy to carry other transmission data. Findings show that the network manageability of this route is very good.
