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.
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

In the United States, an external NT-1 device is required to provide
the U-interface to the carrier network.
