Network

Interface Description

Ethernet and

Second Ethernet Supports the Ethernet and IEEE 802.3 standards that provide LAN connectivity. The

ARN can have up to two Ethernet interfaces -- one on the base module and one on an

expansion module.

The Ethernet interfaces on both the base module and expansion module include a

10Base-T and an 802.3 AUI port; however, you can use only one port (10Base-T or

AUI) on each module at a time.

The 10Base-T interface provides unshielded twisted-pair support; the AUI interface

provides broadband, baseband, ﬁber, and shielded twisted-pair support, depending on

the transceiver and cabling you use.

Token Ring and

Second Token

Ring

Supports the Token Ring and IEEE 802.5 standards that provide LAN connectivity. The

ARN can have up to two token ring interfaces -- one on the base module and one on an

expansion module.

The token ring base module supports a 9-pin (DB-9) STP token ring interface. The

token ring expansion module supports both a 9-pin (DB-9) STP connector and a UTP

connector; however, you can use only one port (STP or UTP) on the expansion module

at a time.

Both token ring connector types support the 802.5 media access control (MAC)

token-passing protocol, the 802.2 Type 1 (connectionless) protocol, the 802.2 Type 2

(connection-oriented) protocol, and the 16-Mb/s Early Token Release (ETR) protocol

over the appropriate cabling.

Serial Provides WAN connectivity. ARN models can have up to ﬁve serial ports (three on an

expansion module and up to two adapter modules).

Each port can operate independently with RS-232, RS-422, RS-449, RS-530, V.28,

V.35, and X.21 cables. Serial capability allows internal or external clocking.

ISDN BRI Supports an S/T or U interface. The BRI provides two B channels, and supports full

D-channel signaling and call setup/tear-down as deﬁned in 1988 CCITT (now ITU-T)

Q.921 and Q.931. For more information on ISDN, functional groups, or reference

points, refer to

Conﬁguring Dial Services

.

The ISDN BRI option is available as an adapter module for any ARN model.

56/64K DSU/CSU Supports a 56/64K DSU/CSU interface.

V.34 Modem Provides a V.34 modem interface.
