repeater with build in bridge function” It is design for low cost dumb HUB application. The
AX88871A directly supports up-to eight 10/100Mbps automatic links MII interfaces. Maximum
up-to 192 ports can be constructed when using inter-repeater bus horizontally cascades 4
AX88871A and vertically cascades 6 repeaters. When using the legacy method, maximum up-to
64 ports can be constructed when using expansion bus cascades 8 AX88871As. The AX88871A
is designed base on IEEE 802.3u clause 27 “ Repeater for 100Mb/s base-band networks” It is
fully compatible with IEEE 802.3u standard.
