Description

 

 

 

Ethernet and

 

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

Second Ethernet

 

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

 

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

Second Token

 

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

Ring

 

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.
