Quality assessment of interconnected digital cellular - public switched telephone networks
Spiros Dimolitsas, F.L. Corcoran, M. Baraniecki · 2002
The quality of interconnected North-American digital cellular and future microcellular networks with 16-kb/s and 32-kb/s digital circuit multiplication equipment/packet circuit multiplication equipment (DCME/PCME)-based switched and private telephone networks is quantified. From these assessments, it is concluded that cellular networks employing the TIA IS-54 8 kb/s vector sum-excited linear predictive (VSELP) algorithm may meet the end-to-end quantization distortion allocation criteria when interconnected with the switched network.>
