      Instantaneous voltage 5 Vpp requirement (TBRs 21
      and 37, normal loud signals)
History

Studies the possibility of using pseudo-speech signal as test stimulation for level limitation requirements. This applies to TE transmitting voice signals and having 2-wire analogue voice band interface.
