iDCS KDB-DIGITAL LINE INTERFACE (FKDBD)
This is a daughterboard that can be installed only in the 18 or 28 button keyset. The
FKDBD will provide one additional DLI circuit for the connection of any digital station
device such as a keyset, add-on module or DPIM. This FKDBD will only operate when
the keyset is connected to an 8 port DLI card so it can use the second B channel. Each
port on this card is intended for connection to one telephone. Connecting multiple
telephones to a port may result in incorrect operation or damage to the card.

iDCS KDB-SINGLE LINE INTERFACE (FKDBS)
This is a daughter board that can be installed only in the 18 or 28 button keyset. The
FKDBS will provide one additional SLI circuit for the connection of any standard
telephone device. This FKDBS will only operate when the keyset is connected to an 8
port DLI card it can use the second B channel. Each port on this card is intended for
connection to one telephone. Connecting multiple telephones to a port may result in
incorrect operation or damage to the card.
NOTE: The circuitry on a FKDBS does not provide a loop open disconnect signal or
have the over-voltage protection necessary for OPX operation.
iDCS KDB-FULL DUPLEX (FKDBF)
The standard speakerphone 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 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.
DS KDB-FULL DUPLEX (KDBF)
This is a daughterboard that can only be installed in the 21D or 14D button keysets.
The standard speakerphone mode of operation for a DS 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. In addition the KDBF 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.
KDB-DLI
This daughterboard can be installed only in the DCS 12 or DCS 24 button keyset.
Before performing this procedure, unplug the line cord from the keyset and remove the
base wedge. Place the keyset face down on a soft surface and remove the four base
retaining screws (see Figure 7.11).
