In either case, the authentication key entered in the Configuration page establishes the
encryption key. For this reason, the authentication key must be the same on each end of
the link. See Authentication Key on Page 212.
Feature Availability
Canopy AES products run the same software as DES products. Thus feature availability
and functionality are and will continue to be the same, regardless of whether AES
encryption is enabled. All interface screens are identical. However, when encryption is
enabled on the Configuration screen
◦ the AES product provides AES encryption.
◦ the DES product provides DES encryption.
Field-programmable Gate Array
Canopy AES products and DES products use different FPGA (field-programmable gate
array) loads. However, the AES FPGA will be upgraded as needed to provide new
features or services similar to those available for DES products.
Signaling Rates for Backhaul Modules
DES BHs are available in both 10-Mbps and 20-Mbps signaling rates. AES BHs are
available with only a 10-Mbps signaling rate.
Upgradeability
Canopy DES products cannot be upgraded to AES. To have the option of AES
encryption, the service provider must purchase AES products.
Interoperability
Canopy AES products and DES products do not interoperate when enabled for
encryption. For example, An AES AP with encryption enabled cannot communicate with
DES SMs. Similarly, an AES Backhaul timing master module with encryption enabled
cannot communicate with a DES Backhaul timing slave module.
However, if encryption is disabled, AES modules can communicate with DES modules.
22.3 MANAGING PASSWORD ACCESS
22.3.1 Configuring Display Only and Full Access Passwords
The Display-Only Access password protection interacts with the Full Access password
protection as described in Table 51.
