Transmission Planning for Private/Public Network Interconnection of Voice Traffic Series G: Transmission Systems and Media Digital Systems and Networks International Telephone Connections and Circuits - Transmission Plan Aspects of Special Circuits and Co
Most of the ITU-T Recommendations in the G-series are presently based on configurations where the national part of an international connection is usually terminated by a single analogue telephone set or by a digital terminal. Consequently, these ITU-T Recommendations do not take into account PABXs (Private Automatic Branch Exchange) or private networks. However, modern private networks, mainly those of large size and/or using new technologies, will contribute in a specific, possibly significant amount to the overall transmission quality.
