Abstract
A cable modem blocks data transfers addressed to host systems during a safe mode of operation and provides the data transfers to the addressed host systems during a normal mode of operation. The cable modem can be coupled to multiple host systems which can be addressed separately. Accordingly, the safe mode of operation can be selected for a subset of the host systems coupled to the cable modem. The safe mode or normal mode of operation can be invoked by pushing a button on the cable modem. The safe mode of operation may also be invoked after the expiration of a timer which times an interval of inactivity at the host. The normal mode of operations can be invoked after detecting activity at the host system.
