Conventions Used in the Manual

In the installation and manager chapters of this manual certain conventions

have been used to distinguish user input from system output.

User input via an attached terminal is indicated by text in boldface with

single key names being enclosed in angle brackets, e.g.

EDIT 4<RETURN>

When two or more keys are to be pressed simultaneously, the convention of

a plus sign between the characters is used, e.g.

<CTRL>+E

indicates that the control key should be held down while the E character is

entered.

1.1 O

VERVIEW

The CLAM Bridge is the latest in a new generation of internetworking

products which specifically address the new needs of Networking in the

90s. It allows home or small office users to take advantage of the latest

technology, combined with new ISDN services to provide economic,

effective and resilient network solutions in today’s LAN environment. As

more power and intelligence is built into the workstation, so

internetworking traffic consists of short bursts of high-volume data.

Previously, users had no option but to pay for unused time on leased lines to

gain the necessary performance. The widespread availability of ISDN

services and the new NET3 standards of operation will allow users to

review their network needs and implement more cost-effective services.

1.2 T

CLAM P

LATFORM

The CLAM (Corporate LAN Access Module) is a very compact bridging

device housed in a lightweight, ergonomically designed moulding. The

communications engine uses the latest RISC technology, while the integral

CLAM Bridge processor uses 32bit-wide pipelined architecture. Both

components are tightly bound together, providing extremely low latency.

These factors make the CLAM probably the most powerful unit of its size.

1.3 ISDN A

UTOCALL

ANDWIDTH ON

EMAND

The CLAM Bridge can be configured to establish ISDN calls automatically

to a destination based on either LAN destination MAC (Medium Access

Control) or network address of incoming data frames. Calls are usually

established instantly and cleared automatically on no data being transmitted

for a configurable period. Autocalls can use Top-Up-On-Demand to

establish multiple ISDN links if needed due to high link utilisation. CLAM

Bridge supports TCP/IP, OSI, IPX and Banyan Network addressing; all

other protocols use MAC address autocalls. This is an ideal use for ISDN

where the cost of connection time for real data transmission to sites is lower

for ISDN than the cost of leased lines. High speeds and fully automatic

operation give the “feel” of leased lines without the cost.

1.4 P

ROTOCOL

RIDGING AND

POOFING

Many Client/Server-based network protocols broadcast frames regularly,

making them unsuitable for cost-effective bridging or routing using ISDN.

The CLAM Bridge solves this by filtering Broadcast and Multicast frames

and spoofing (imitating) the protocols whilst no user data is present. For

Novell IPX/SPX, the CLAM Bridge acts as a combined Server/Router on

the LAN, emulating the RIP and SAP frames and reacting to Client-based

requests for attachment to networked services. This ensures ISDN is only

used for transmitting real data, and network information is updated

automatically during the connection. Banyan Vines is supported in a similar

way.

1.5 S

IMPLE

NSTALLATION AND

ANAGEMENT

The CLAM Bridge is designed to be installed and operating within minutes

after connection to the network. The CLAM Bridge automatically learns all

MAC addresses on the network and sets up the necessary tables. Selection

criteria can be specified using Manager Menus. The built-in management

system can be accessed via a Telnet call, or from a serial-connected ANSI

terminal device.

The CLAM Bridge incorporates extensive diagnostic and management

facilities to allow the administrator to gain knowledge of the LAN and

WAN operation on all local and remote bridges.

Software upgrades may be downloaded remotely using ISDN or locally,

from another CLAM or from a PC.

1.6 S

ECURITY

As a public service, ISDN could open your network to unauthorised access.

The CLAM Bridge is equipped with several features designed to maintain

security.

The CLAM Bridge features two levels of access security which are invoked

automatically and are transparent to the user. Calling Line Identification

(CLI) is supported, which ensures incoming ISDN calling numbers are

checked before access is granted. The CLAM Bridge has a second layer of

security, based on the encoded MAC address of the calling bridge. If this

address is incorrect, the remote unit will be unable to send or receive data.

· ISDN connection cable included

Bandwidth Aggregation

· 2 ISDN B-channels may be configured to a particular destination,

providing a combined bandwidth of 128Kbps

Data Compression

· Effective throughput increase between 2 and 8 times

(typically 192Kbps from a 64Kbps channel)

Spanning Tree Algorithm

· IEEE Standard for multivendor interoperability

Security

· Data scrambling on serial links

· Access control on management functions

· ISDN access authorisation list

· Calling Line Identification

Management

· Local terminal management with easy to use menu driven

management

· Direct status and statistics reporting, simple configuration capability

· Accessible from networked TCP/IP stations

· Remote Management

· SNMP (Simple Network Management Protocol) capability

Optional Expansion Module

The CLAM Bridge has an expansion slot that allows you to install the

following optional expansion module:

· An analogue voice module, providing a PSTN interface to support

conventional analogue devices

Optional Analogue Voice Module

· Provides a single RJ-11 interface

· Allows a standard analogue PSTN device e.g. telephone, fax, modem

etc. to make and receive calls from other ISDN or PSTN connected

devices

· Eliminates the need for a separate PSTN line in a SOHO (Small

Office Home Office) environment
