Provides guidance for transmission planning of modern telecommunication networks. The primary emphasis is on provisioning of telephone connections. The transmission plan established by this Recommendation takes into account transmission parameters and impairments, different network configurations and elements and modern transmission techniques, as well as the effects resulting from the combination of the various factors having influence on the resulting transmission quality.
