ABSTRACT:
In a bidirectional CATV system, terminal devices at individual subscriber locations are arranged in sets, with each terminal device in a set being coupled to an intermediate polling processor which includes means for storing status data as to each of the terminal devices. The head end system polls the intermediate processors for their consolidated reports, with the result that tens of thousands of subscriber locations can be serviced without inordinate delays by a single head end system.
