2 Data Sheet Marlin Network Access Servers

Benefits

Extends Connectivity

Marlin Network Access Servers support

Ethernet,Synchronous,and ISDN BRI,

providing ﬂexible remote ofﬁce and wide

area connectivity. Bay Networks Dial

Backup provides connectivity to the cor-

porate backbone on an as-needed basis,

ensuring cost-effectiveness. Bay Networks

adherence to standards allows connectivity

and interoperability for TCP/IP networks

over ISDN, Frame Relay,and leased lines

in multivendor environments.

Ensures Network Performance

and Availability

By supporting 10,000 pps forwarding and

14,880 pps ﬁltering rates,Marlin Network

Access Servers ensure high-performance

LAN access. What’s more,the Marlin’s

Dial-on-Demand,Dial-Around-Dead

Site(DADS),and Bandwidth-on-Demand

features ensure network availability dur-

ing periods of dislocation and high trafﬁc

congestion,offering protection against

business disruption in the event of a dis-

continuity in the selected data path.

Marlin Network Access Servers can be

conﬁgured by a wide array of local and

remote SNMP-based management plat-

forms,which allow for easy conﬁguration

and quick problem resolution.

Protects Investment

The Marlin Network Access Servers are

compatible with Bay Networks CLAM

™

Access Node (AN

),Access Node Hub

(ANH

™

),Access Stack Node (ASN

™

Backbone Link Node (BLN

), and

Backbone Concentrator Node (BCN

)

routers. Additionally,Marlin Network

Access Servers can interoperate with

third-party vendors equipment using PPP,

Multilink PPP,Bandwidth Allocation

Control Protocol (BACP), Compression

Control Protocol (CCP),and Microsoft

Point-to-Point Compression.

Hardware Features

High-Performance Processor

The high-performance, highly ﬂexible

Marlin Network Access Servers feature a

MIPS 33000,MC68360, and an MC68302

microprocessor for I/O interface,provid-

ing a ﬁltering rate of 14,880 pps and

forwarding performance that exceeds

10,000 pps.

Each Marlin Network Access Server con-

tains 4 megabytes (MB) RAM and 1 MB

Flash memory. Software image and conﬁg-

uration ﬁles can be downloaded remotely

to the Flash memory, simplifying upgrades

and fault recovery procedures.

LAN and Serial Interfaces

Marlin Network Access Servers are

available in conﬁgurations that

support Ethernet, Synchronous,and

ISDN BRI to meet a wide variety of

connectivity requirements.

Ethernet All Marlin Network Access

Servers feature a 10BASE-T (RJ-45)

connector and one AUI connector for

a choice of connectivity. The interface

supports IEEE 802.3 and Version 1.0/2.0

Ethernet frame formats.

Synchronous The Synchronous WAN

interface supports clocking rates up to

2.044 Mbps. It is available conﬁgured

with a V.11/X.21,V.24/RS-232, or V.35

physical interface for support of Frame

Relay or leased line services. The V.24

interface also supports connection to an

analog modem for public-switched tele-

phone network (PSTN) dial-up routing.

Integrated Services Digital Network (ISDN)

Basic Rate Interface (BRI)

Marlin Network

Access Servers’support of ISDN BRI sup-

plies two 64 Kbps B-channels for data and

one 16 Kbps D-channel for signaling to

provide an integrated,high-performance

solution for companies using dial services.

Marlin Network Access Servers’ISDN

BRI connector is an RJ-45. The Marlin

Network Access Servers can be equipped

with up to three ISDN S/T interfaces.

Software Features

Nautica Routing Services (NauticaRS)

Available for all Marlin Network Access

Servers,NauticaRS software enables the

Marlin to maximize connectivity through

standards-based protocol features and

services (see Table 1). Nautica RS sup-

ports static and IP routing, RIP and RIP

version 2,and Novell IPX/SPX. It also

complies with Point-to-Point Protocol

(PPP) and Multilink PPP (MP) standards

to provide connectivity for TCP/IP net-

works over ISDN,Frame Relay,and

leased lines to other third-party routers.

NauticaRS support of RFC 1490

encapsulation enables multivendor inter-

operability for Frame Relay networks.

It also features Transparent bridging.

NauticaRS supports several standards-

based data compression algorithms to

ensure high-performance networking.
