I had an opportunity to buy a second hand Anderson Jacobson AJ211 acoustic
coupler.
Unlike the AJ311, the AJ211 provides the originate mode only.
However, the housing and the printed circuit give the impression that an
hardware-upgrade would be not too expensive.
Does anyone know how the A211 would have to be modified or has anyone the
circuit layout of A211 and/or A311?

Thanks in advance,
Alexander Ortloff
