The default for all 4 keys is a string of 10 zeros (no key).
Wireless Media Security
Wireless media security is provided by preventing the ability to perform
data sniffing on the air. Encryption functionality is achieved by using
the modem scrambler. The scrambling algorithm is based on two
parameters - a polynom and a seed. In order to be able to extract wire-
less data the receiver must have the same polynom and seed as the
transmitter. The wireless media security feature enables changing the
polynom and the seed used for the scrambling operation, thus insuring
that only units with the same polynom and seed may interact with each
other. Enhanced security is achieved by using 16-bit length seeds and
up to 16-bit polynoms.
The available parameters are:
! Encryption Seed – Defines the index of the 16-bit encryption seed
to be used for wireless media security.
Valid values are from 1 to 127.
The default is
7 .
! Encryption Polynom Index - Defines the index of the up to 16-bit
encryption polynom to be used for wireless media security.
Valid values are from 0 to 9.
The default is
0 .
