Computer Networks and Internet - Overview
Distribution Hub The hub is the interchange point between the regional fiber network and the cable plant. At the hub, the cable modem termination system (CMTS) coverts data from a wide area network (WAN) protocol, such as POS, into digital signals that are modulated for transmission over HFC plant, and then demodulated by the cable modem in the home or business. The CMTS unit provides a dedicated 27 Mbps downstream data channel that is shared by the 500 to 1,000 homes served by a fiber node, or group of nodes. Upstream bandiwdth per node typically ranges from 2 Mbps to 10 10 Mbps. Source http://www.cabledatacomnews.com/cmic/hub.html
