Abstract
A method, system and computer program product for operation of a cable modem in response to Alternating Current (AC) power outage is described herein. When a loss of AC power is detected, the cable modem is switched to battery backup mode of operation using a single upstream and a single downstream channel. This switch occurs prior to receiving instructions from a cable modem termination system to use a single upstream and a single downstream channel. The cable modem notifies the cable modem termination system of the switch to battery backup mode of operation.
