DES ENCRYPTION
DES (Data Encryption Standard) is a secret key encryption scheme. The basics of DES are that it
performs a series of bit permutations, substitutions, and recombination operations on blocks of
data utilizing a secret key. On the Cyclone system, DES encryption of the over the air link is done
on a per access point module or backhaul timing master module basis and does not affect the
performance or throughput of the system. The Cyclone modules contain unique factory
programmed secret keys to establish the encrypted link.
INSTALLATION
The following steps are required to install the Cyclone module:
Unpack the Cyclone products
Configuration of the modules
Installation of the modules
Alignment
UNPACK THE CYCLONE PRODUCTS
Upon receipt, carefully inspect all shipping boxes for signs of damage. If there is damage,
immediately notify the transportation company.
Unpack equipment, making sure that all ordered components have arrived. It is recommended
that you save all the packing materials. They can be used for transportation of the equipment to
and from installation sites.
CONFIGURATION OF THE BACKHAUL MODULES
In all cases, when a configuration parameter is modified, the change must be saved and
the module must be rebooted.
All backhaul modules, from the factory are configured as backhaul timing slaves. The following
are items that an operator will need to verify and/or configure for each module:
Will the module be a timing master or timing slave?
If it is a Timing Master
There are two methods that can be utilized to configure each of the backhaul timing masters. The
first method is to utilize the Quick Start feature of the product. For more information on Quick
Start see The Interface Screens. The second is to manually set each of the parameters.
Will the backhaul module need to generate its own sync pulse or will it receive it from the
cluster management module?
The operator will assign a RF frequency for the module to transmit.
The operator will assign an IP address to the module for the network it will be installed on
and assign an appropriate subnet mask and network gateway.
The operator must configure the appropriate color code on the backhaul timing master
module so that the backhaul timing slave module can register with it. The color codes
must match for registration.
