Figure 7.11 Adding an iDCS KDBF Keyset Daughtercard Module
iDCS KDB-FULL DUPLEX (FKDBF)
This daughtercard can only be installed in the iDCS 28 and iDCS 18 button phones. The
standard speakerphone mode of operation for an iDCS keyset is “half duplex”. This means
that you cannot transmit and receive speech at the same time. Adding a FKDBF to your keyset
will convert the speakerphone into full duplex mode enhancing its operation. In addition, the
FKDBF may have up to 3 external microphones attached to it for conference room type
applications. These microphones require an “EXTMIC” key programmed on the keyset to
activate or deactivate them.
