it is a custom ASIC, perhaps featuring some logic.
without this logic (clocked on ACI line of POP port) your phone would have *only* MONO output (for backwards compatibility with mono headsets).
more on this later.

Maybe it is a stupid question, but i need some pinout for handsfree that will work with nokia 6170 in MONO mode (for talk). I have never dealed with Nokia before, and I failed to find a service manual for this phone. What scheme (or what handsfree model) can i use?
