摘要
A hybrid fiber/coaxial cable is attached to an autonomous controller which includes a wireless receiver, transmitter, and antenna. Typically, the autonomous controller is connected near the end of the cable which is remote from the headend. At least one other hybrid fiber/coaxial cable connected to the same headend or distribution hub, provides connectivity for cable data modems and set top boxes in an adjacent neighborhood or community. The second cable is attached to its own, respective autonomous controller which also has a wireless receiver, transmitter, and antenna. The two antennas in the adjacent neighborhoods constitute an antenna cluster. When the first cable's connection to the common headend is interrupted, thereby preventing service to the first neighborhood, its autonomous controller senses the interruption and responds by sending a wireless signal to the controller in the adjacent neighborhood. In response, the two controllers use an antenna cluster protocol (ACP) to set up a wireless communications path through the second cable to the headend. In this manner, service is restored from the headend to the cable data modems and set top boxes in the first neighborhood.
