ETSI ETSI TS 143 050 V13.0.0 (2016-01)73GPP TS 43.050 version 13.0.0 Release 131 Scope The present document describes the transmission planning aspects pertaining to the speech service in the G
23、SM PLMN system. Due to technical and economic factors, there cannot be full compliance with the general characteristics of international telephone connections and circuits recommended by the ITU-T. The present document gives guidance as to the precautions, measures and minimum requirements needed fo
24、r successful interworking of the PLMN with the national and international PSTN. The present document identifies a number of routeing and network configurations. The objective is to reach a quality as close as possible to ITU-T standards in order to safeguard the performance seen by PSTN customers. T
