Notice!
128-bits AES Rijndael encryption can be used in DCN Wireless systems. The encryption key is
not stored in the Wireless Access Point (DCN-WAP), but in the Central Control Unit (DCN-
CCU2). The DCN-WAP receives the key after connecting to the DCN-CCU2.The DCN-CCU2 and
Wireless Discussion Units (version 4.0 or higher) have a default encryption key. Wireless
Discussion Units with older versions or with changed encryption keys can not be subscribed
and can therefore not be used with a DCN-CCU2 that has the default key and has encryption
enabled.The encryption key of the DCN-CCU2 and Wireless Discussion Units can be changed
with the Download & License Tool delivered on the DVD that came with the central control
unit.By keeping the key field in the Download & License Tool blank (empty), the default
encryption key of the DCN-CCU2 and Wireless Discussion Units can be restored.
