IP-based networks developments highly integrate the communication systems and significantly reduce the installation cost. Digital PLC systems with the capability of Ethernet and VoIP services are designed because of the demand of new communication services in the electric power industry. Also due to the limited bandwidth in digital PLC systems, there are several techniques for optimal use of transmission capacity. In this paper, the possibility of using VoIP services in digital PLC systems has been investigated. Many conventional standards are studied for several parameters such as total algorithm delay, voice payload size/duration, packets per second, and bandwidth to select the best codec. Finally, a proper codec is recommended to employ in the digital PLC's VoIP service according to the two important factors in quality of voice services, i.e. available bandwidth and latency.
Voice codec, Bandwidth, Delay, Digital PLC, PLC Link Transition, VoIP.
