Abstract
A communication system includes a station-side terminal apparatus and multiple subscriber-side terminal apparatuses connected to the station-side terminal apparatus. The station-side terminal apparatus is configured to, in response to receipt of a packet from a subscriber-side terminal apparatus, a packet indicating whether data distribution is required, identify the subscriber-side terminal apparatus that has transmitted the packet, and transmit a packet indicating an address for which whether the transfer of distribution data is required is designated to the subscriber-side terminal apparatus based on whether data distribution is required. Each subscriber-side terminal apparatus is configured to, in response to receipt of a distribution packet, if the distribution packet has the address for which whether the transfer of distribution data is required is designated, transfer the distribution packet to host apparatuses accommodated thereto or prohibit the distribution packet from being transferred to the host apparatuses accommodated thereto.
