This article is devoted to the research of VoIP transmission quality over Digital Power Line Carrier channels. Assessment of quality transmission is performed using Emodel. Paper considers the possibility of joint using of Digital Power Line carrier equipment with different architecture in one network. As a result of the research, the rule for constructing of multi-segment Digital Power Line Carrier channels was formulated. This rule allows minimizing the transmission delay and saving frequency resources of high voltage Power Line Carrier range.
