6.2 Ringing signal reception
6.2.1 Ringing signal detector sensitivity
The ringing detection circuitry or ringer of the TE shall be activated
within the time t r (ms) when ringing
signals generated by an ac source "e" connected in series with a dc
source (V f ) are applied to the line
terminals (see figure A.6.2.1). The requirements shall be met in the
specified voltage ranges DU(ac) and
DV f , in the specified frequency range Df and with the series
resistance DR f . The requirement values DU,
DV f , Df and DR f are shown in table 6.2.1.
Compliance shall be checked using the test outlined in A.6.2.1.
