cable modem updis

The cable modem updis command enables the transmission of an an Upstream Transmitter Disable (UP-DIS) MAC layer message that disables a specified cable modem’s upstream transmitter. Upon receipt of an UP-DIS message, the cable modem autonomously disables its upstream transmitter. Once disabled through an UP-DIS message, the cable modem’s upstream transmitter can only be re-enabled by power cycling the cable modem.

The cable modem updis command is not intended to be a replacement for existing mechanisms for controlling a subscriber’s service. The cable modem updis command provides an additional tool to protect against some forms of denial of service, such as a virus propagated across the Internet, that cannot be controlled with existing management mechanisms.
