ADC Telecommunications, Inc. 109
WIRELESS PROTECTION PARAMETER
The parameters that are visible depend on the settings you make for the Use dynamic key rotation.
Keys 1, 2, 3, 4
The number of characters you specify for a key determines the level of encryption the LPS-20x will provide.
• For 40-bit encryption, specify 5 ASCII characters or 10 HEX digits.
• For 128-bit encryption, specify 13 ASCII characters or 26 HEX digits.
When encryption is enabled, wireless stations that do not support encryption cannot communicate with the
LPS-20x. The definition for each encryption key must be the same on the LPS-20x and all client stations. Keys must
also be in the same position. For example, if you are using key 3 to encrypt transmissions, then each client station
must also use key 3 to communicate with the LPS-20x.
Transmission Key
Select the key the LPS-20x will use to encrypt transmitted data. All four keys are used to decrypt received data.
Key Format
Select the following format you use to specify the encryption keys:
ASCII
ASCII keys are much weaker than carefully chosen HEX keys. You can include ASCII characters between 32 and
126, inclusive, in the key. However, note that not all client station support non-alphanumeric characters such as
spaces, punctuation, or special symbols in the key.
HEX
Your keys should only include the following digits: 0-9; A, B, C, D, E, F (not case sensitive)
