Connector Pinouts
This section lists pinouts for the AN/DC and ANH-8/DC connectors:
• Attachment Unit Interface (AUI) Ports
• 10Base-T Repeater Ports (ANH-8/DC only)
• Synchronous Interfaces
• ISDN BRI Ports
• Local Console Connections
Table C-2. ANH-8/DC Network Interfaces

Interface Description
Ethernet The ANH-8/DC supports eight 10Base-T UTP repeater ports and one
802.3 AUI port; however, you can use only one port at a time. These
interfaces comprise a single managed segment, supporting the
Ethernet and IEEE 802.3 standards that provide LAN connectivity.
Some ANH-8/DC models also include an Ethernet UTP port on the
back panel. This second Ethernet interface is not a repeater port.
Synchronous Provides WAN connectivity via either two (COM1 and COM2) or
three (COM1, COM2, and COM3) synchronous ports.
Each port can operate independently with RS-232, RS-422, V.28,
V.35, and X.21 cables. Synchronous capability allows internal or
external clocking.
ISDN BRI Supports an S/T interface (an RJ-45 physical connector). The BRI
provides two B channels, and supports full D-channel signaling and
call setup/tear-down as defined in 1988 CCITT Q.921 and Q.931. For
more information on ISDN, refer to
Configuring Dial Services
.
In the United States, an external NT-1 device is required to provide
the U-interface to the carrier network.
