KDB-F
The standard mode of speakerphone in DS-5021D/5014D phone is ‘Half Duplex’. The
half duplex means that it can communicate in both directions but only one way at a
time. The KDB-F enhances the speakerphone mode to the full duplex, so it can provide
better communication. Connecting up to 3 external microphones to the KDB-F module,
a conference can use this in a very convenient way. To use this function, the phone
shall have the pre-programmed EXTMIC button.
AOM
There is AOM(Add On Module) other than the KDB modules, as for the additional modules
that provide various functions by connecting to the DS-5021D/5014D phone.
The AOM is a button expansion box that is composed of programmable buttons only. The
DS-5021D/5014D phone can connect AOM of 64 buttons. If the AOM module is installed,
that means more programmable buttons are added. Then more functions can be registered
for convenient use.
