KX-TDA6181X 7.2.4. Bell Signal Detection During on-hook, transmitting the bell signal to the AC loop in the CR series circuits (C2 and R2) detects the current by Photo Coupler (PC1,2), and it determines the presence of a bell signal. Software performs the operation for recognition and determination of a pattern of bell signals.

KX-TDA6181X 7.2.7. 2W-4W Conversion This converts 4W-voice signal inside PBX and 2W-voice signal on SLT or Trunk. It is configured by Op-Amp and BN (Balance Network) in CODEC. It affects the return loss of the voice and the frequency characteristic, and is determined by setting the best value of Infineon CODEC and a software register.
KX-TDA6181X 7.2.10. Power Failure Port At the time of the power failure, for enabling a direct call to the extension phone, 4lines out of 16lines can be connected to the SLT port, which provides a switching relay for power failure on the extension card, by a cable. It connects CN3, CN4 with the connector for power failure on the extension card.
