3.2 Stability Loss

3GPP43.050Release 17Transmission planning aspects of the speech service in the GSM Public Land Mobile Network (PLMN) systemTS

Tools: ARFCN - Frequency Conversion for 5G NR/LTE/UMTS/GSM

The stability loss presented to the PSTN by the PLMN at the POI shall be as specified for the stability loss presented to the PSTN by the 3GPP network in [49], 3GPP TS 26.131.

For a dual mode GSM/3GPP telephone as well as a single mode GSM MS compliance shall be checked according to the procedures described in [50] , 3GPP TS 26.132.
