Connecting the AUI Port to a Coaxial Backbone
You can use the AUI port to connect an AN or ANH to a coaxial backbone through
an IEEE 802.3 10Base-5 or 10Base-2 coaxial MAU.
Figure C-
4 shows two ANH systems connected to a coaxial backbone through
IEEE 802.3 MAUs. An AUI cable connects the AUI port on each ANH to each
MAU. The SQE test is disabled on each MAU connected to the AUI port on an
ANH.
