Abstract
A number of remote interrogator units is connected in a branch of a broadband multichannel cable network for receiving and storing subscriber drop channel information from the network headend, and selectively passing communication information to the headend. Several of groups of expansion modules are connected in the cable branch, each module controlling a number of subscriber drops or terminals and all modules in one group being accessible by one of the interrogators. Band stop filters are associated with each interrogator to isolate a group of expansion modules for isolation of a branch segment to one interrogator, and permitting other modules to be controlled by other interrogators in other isolated segments.
