Manual Operation
When Access Protection is set to Enable by the end user of the WebWizard, inbound
data destined for the CPE is blocked at the wireless home gateway. This data is not
allowed to pass through to the CPE, but the local network on the CPE side of the
wireless home gateway remains fully operational. This fully operational state
includes maintaining an "up" status for the link between the wireless home gateway
and the CPE.
Important! When wireless home gateway access protection is set to Enable, the
Network Administrator has the ability to operate, maintain, and provision the
wireless home gateway at all times just as though there were no access protection in
place. The exception to this is that the network operator will not be able to
communicate directly with any CPE while the wireless home gateway is in the
access protection enabled mode, even though the link status to the CPE may read
"Operational."
Notes:
CPE devices bridged together between the USB and Ethernet ports are still able

to communicate with each other, and the Ethernet link status responds as
"Operational" should the Network Administrator ping the wireless home
gateway to determine the status of the CPE links.
After Cable Modem Access Protection is enabled by the CPE through the

WebWizard, the wireless home gateway remains in the Access Protection mode
until the mode is manually set to Disable by the CPE through the WebWizard
interface, or, if necessary, by pressing the wireless home gateway Reset button.
Automatic Mode
Cable Modem Access Protection also supports an Automatic mode of CPE access
protection. In this mode, the wireless home gateway monitors outbound data from
the CPE to the network, and, based on that traffic, makes a decision as to when to
activate the access protection mode.
If no user outbound activity occurs (no user-generated upstream transactions) for a
user-defined period of time, the wireless home gateway activates the protection
mode automatically and remains in that mode until it detects outbound data
activity. When outbound data activity resumes, the wireless home gateway
automatically disables the access protection mode and resumes normal operation.
Important! The user defines the time setting for the duration of inactivity that must
occur before the system automatically enables the access protection mode.
Note: Some background programs running on the CPE may prevent the wireless
home gateway from going into Access Protection. These programs generate Internet
traffic on a regular basis that can reset the automatic timer.
