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.

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.

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.

UTOCALL
B
ANDWIDTH ON
D
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.

RIDGING AND
S
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.

NSTALLATION AND
M
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.

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
