Thank you for adding the CLAM to your networking environment. CLAM
revolutionises traditional networking by including the intelligence to self-
learn many parameters. You should find the CLAM easy to install and use,
especially if you follow the step-by-step instructions relevant to your CLAM
configuration in this “Easy Start” guide. When you become familiar with
the CLAM and its management as described in the EZ S

will provide more detailed information.
The physical installation should take place on a flat surface, in a clean, dry
location with no extreme temperatures. Make sure that all services needed
(power, LAN, ISDN, etc.) are within reach and are working correctly.
The CLAM can be located almost anywhere that is convenient for
connection to the power supply, the LAN and ISDN, as long as temperature
and humidity conditions are met. There should be an air gap above and on
all sides of the CLAM, to ensure that the maximum temperature limit is not
reached.
Parameter Specification
Power Supply (Europe and U.K.) 220-240V AC 50Hz (nominal)
Power Supply (North America) 100-125V AC 60Hz (nominal)
Supply Current 60 mA
Power Consumption 15 Watts
Operating Temperature 5 to 45 degrees C
Humidity 5% to 95% (non-condensing)
LAN Cable Maximum Length 100m

• Your ISDN circuit should conform to EURO-ISDN (otherwise known as
NET3 or iCTR3) standards.
• Each ISDN BRI (Basic Rate Interface) should terminate in a wall socket
RJ-45 interface.
• You should know the ISDN number(s) of your local and remote sites.
• If you require CLI (Calling Line Identification) for security, then order
the CLI option from your local carrier.
• If possible, order both B Channels to have the same ISDN number. This
is sometimes known as Auxiliary Working and can speed up connect
times.

In North America you must configure your ISDN BRI ports for the type of
switch your telephone company has in its local central office. Please see the
booklet Ordering Basic Rate ISDN (shipped with North American product
variants only) for full details. You need the following items of information
from your telephone company:
• Whether your line is configured in the standard National ISDN mode, or
in a manufacturer-specific “custom” mode.
• Whether the ISDN link is a Point-to-Point or a Multipoint interface.
• The type of switch: National ISDN2, AT&T 5ESS5, Northern Telecom

ONFIGURATION
The following initial setup should be done on all CLAM installations, using
the COnfigure SYstem form.
• Set the CLAM Name. This name should be descriptive, but must be
unique within the set of CLAMs likely to talk to each other. Note: the
name should not include blank spaces, punctuation or special characters,
except _ (underscore).
• Set the CLAM IP Address. This address should be provided by the
network administrator, and should be consistent with your company
addressing policy. Note that if you change the IP Address over TCP/IP,
then the current session will hang up: you must disconnect the session
and then TELNET again using the new IP Address.
• If required, set the CLAM password. Note: passwords are case-sensitive.
After completing any (re-)configuration, always type SAVE to ensure that
the changes made are maintained across power cycles.

The CLAM can be set up to recognise IP traffic. Once this is done, the
CLAM makes the ISDN calls needed when a user has data to send or
receive, and ends the ISDN calls when the links are idle. First, the topology
of the IP network must be configured manually into each bridge as follows:
EZ
S
TART
Page 18 Issue 3.0
1. Use the COnfigure ISDN NUmbers form on the OfficeCLAM to add the
ISDN numbers of all remote bridges (see Figure 7-1). Add an entry for
each bridge likely to be connected. Unit names must match exactly the
names of the remote units (e.g. upper and lower case). On the remote
bridge, add the name OfficeCLAM to the list of ISDN numbers.
2. Use the COnfigure ISDN AUTOcalls form on the CLAM to set up the
Autocall table. An Autocall entry defines which packet destination will
start an ISDN connection. The CLAM understands IP addressing and
subnetting. For the network in Figure 7-1, the following entries should
be made in the Autocall tables of the two bridges:
