3.12 Requirements for information tones

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 PLMN should be capable of transmitting information tones generated by the PSTN conforming to I‑ETS 300 245‑7.
