5000 Series Keyset Daughterboards
[DS-5014D, DS-5021D and DS-5038S Keysets Only]
DS-5014D, DS-5021D and DS-5038S keysets support one of three different types of daugh-
terboards installed on them to enhance operation or to provide an additional local port de-
pending on the type of daughterboard.
KDB-Digital Line Interface (KDB-DLI)
If your keyset is connected to a Digital Line Interface (DLI) port that supports
2B+D operation, you may install a daughterboard that provides a Digital Line
Interface (DLI) port for connection of a digital station device such as a keyset
or 64 button add-on module.
KDB-Single Line Interface (KDB-SLI)
If your keyset is connected to a Digital Line Interface (DLI) port that supports
2B+D operation, you may install a daughterboard that provides a Single Line
Interface (SLI) port for connection of a standard telephone device such as a
cordless phone.
KDB-Full Duplex (KDB-F)
The standard speakerphone mode of operation for 2-line LCD keysets is "half
duplex". This means that you cannot transmit and receive speech at the same
time. Adding a KDB-F to your keyset will convert the speakerphone into full
duplex mode, enhancing its operation. In addition, the KDB-F may have up to
three 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.
