A system for integrating multiple repeaters (102, 104) into a single collision domain employs both analog and digital circuitry to convey system-wide collision information to repeaters thereby allowing seamless integration of multiple repeaters (102, 104) into multiple hubs (100) without requiring additional drivers or external glue logic. One signal line (CFSL 112) within each hub is used to aggregate collision information within the hub. Further, only one signal line (CFSS 108) is used to aggregate collision information between hubs (100). This latter signal line in conjunction with two intra-hub signal lines (COLZ, 116 and SNGLZ, 114) distributes system-wide collision information to all of the repeaters (102, 104) in all of the hubs (100).
