312410-A Rev 00
Attachment Unit Interface (AUI) Ports
The AN/DC back panel and ANH-8/DC front panel contains a standard 802.3
AUI DB-15 receptacle connector with a slide lock for connection to the AUI. You
can use the Order No. 7115 Ethernet cable, described in the Cable Guide for
Routers and BNX Platforms, for connections to this port.
The AUI transceiver (XCVR) port provides broadband, baseband, fiber, and
shielded twisted-pair support, depending on the transceiver and cabling you use.
The AUI interface connects internally to the Ethernet repeater.
Table C-5
shows the pin assignment for the standard 15-pin AUI receptacle and
identifies its pin locations.
Note:
The AUI port is designed only for connection to a transceiver.
Connecting the AUI port directly to the AUI port on an Ethernet station
(without a transceiver) violates IEEE 802.3 standards.
