The DKT2010-S, DKT2010-SD, DKT2020-S and DKT2020-SD models enable users to make
both internal and outside calls without lifting the handset (see Table 32).
The DK2020-FDSP enables handsfree speakerphone use with the option to switch between “full-
duplex” (concurrent speech) and “voice switch” (alternating conversation between telephones). It
has also been designed to work with an optional, external, super-directional microphone (RFDM)
for enhanced full duplex performance.
