... Active - NP (normal polarity (reverse polarity) Mode selected to allow voice signal transmission. When in ACTIVE mode V the voltage drop in on-hook condition is 7.8V. Concerning AC characteristic the STLC30R81 allows to set 2Wire termination impedance by means of external scaled impedance. In ACTIVE mode the SLIC can perform battery reversal in a soft way, with programmable transition time, without affecting the AC signal transmission ...

... This particular ring trip method, allows to operate without DC offset superimposed on the ring signal and therefore, obtain the maximum possible load driving capability, from a given negative battery. After Ring/ Trip detection, DET pin is set Low and remains latched keeping the STLC30R81 in Stand-by mode until the op- erative mode is modified by Input Word. ...
