AUI Port
A-5
Fanning out the
Telco Connector
You can fan out the eight ports of the Telco connector to eight 8-pin RJ-45
jacks using a patch panel (described in “Patch Panel”) or to eight 6-pin RJ-12
jacks using an octopus (hydra) cable (described in “Octopus (Hydra) Cable”).
The resulting pin numbers are shown in Table A-4. For signal names and
directions, refer to Table A-2 and Table A-3.
AUI Port
Figure A-2 shows pin numbers for the AUI port on the single-port AUI
module. Table A-5 lists pin assignments for the AUI port. This connector is
an industry standard derived from IEEE Standard 802.3.
