CHAPTER 8. Installing KDB (Keyset Daughter Board)

8.3 iDCS FKDBF (KDB-Full Duplex)

The standard speakerphone mode of operation for an iDCS phone is 'half duplex'.
This means that you cannot transmit and receive speech at the same time. Adding a FKDBF
to your phone 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
phone to activate or deactivate them.

8.4 KDB-DLI

This daughter board can be installed only in the DCS 12 or DCS 24 button phone.
Before performing this procedure, unplug the line cord from the phone and remove the
base wedge.
Place the phone face down on a soft surface and remove the four base retaining screws.
Separate the base from the phone and place the phone aside. Attach the KDB-DLI to the
phone base with the four screws that are supplied. Take care to ensure that the modular
socket shows through the access hole in the base invert the base assembly over the phone
and plug the ribbon cable into the socket on the phone PCB while making sure that no
damage occurs to the phone PCB. Reattach the base to the phone and test to ensure normal
phone operation.

8.5 KDB-SLI

This daughter board can be installed only in the DCS 12 or DCS 24 button phone.
Before performing this procedure, unplug the line cord from the phone and remove the
base wedge.
Place the phone face down on a soft surface and remove the four base retaining screws.
Separate the base from the phone and place the phone aside. Attach the KDB-SLI to the

occurs to the phone PCB. Reattach the base to the phone and test to ensure normal phone
operation.

8.6 Connecting to the KDBS

There are two methods for connecting devices to keyset daughter boards.
The simplest method is to connect the second device directly by means of a line cord.
The second method is to use a multi-pair station cable, connecting separate station jacks to
the first two pairs. A line cord can now be connected between the daughter board and the
second jack.
This returns the daughter board port to the MDF for cross-connection to another cable run.
