DS-KDB-FULL DUPLEX INTERFACE (DS-KDBF)
This is a daughter board that can be installed only in the DS 5021D or DS 5014D keysets. The standard speaker-
phone mode of operation for a iDCS keyset is "half duplex" . This means that you cannot transmit and receive
speech at the same time. Adding a KDBF to your keyset will convert the speakerphone into full duplex mode
enhancing its operation. The FKDBF does not require a second "B" .
Note: Only one KDB can be installed on a keyset.
