OSTS
In no event shall Lightning be liable for costs incurred by a user on its ISDN line.
The Multi Com LAN Access Center is designed to open and close ISDN lines auto-
matically, depending on traffic on the Ethernet and ISDN line and on parameters
set in the configuration. Front-panel signals and specific commands may indicate
the current state and activity of the ISDN line, and the user should keep an eye on
those status indications to avoid excessive bills, due to misconfiguration, protocol
errors, polling applications, potential software or firmware errors and so forth.
THE USER AND THE USER ONLY IS SOLELY RESPONSIBLE
FOR ALL INCURRED ISDN COSTS.

Installation
1
The MultiCom LAN Access Center is a device
designed to connect remote Ethernet networks
through Basic-Rate ISDN, Primary-Rate ISDN or syn-
chronous serial leased lines. It is easy to install and
works with standard TCP/IP and IPX/SPX software. To
set up your MultiCom LAN Access Center, simply fol-
low the steps described in the following chapter.

CHAPTER 1INSTALLATION CHECKING YOUR PACKAGE CONTENTS
8MultiCom LAN Access Center — User’s Manual
CHECKING YOUR PACKAGE CONTENTS 1.1
Firstly, please check the packing list on the reverse side of the cover.
If something is missing or if the product is received damaged, forward an imme-
diate request to the delivering carrier to perform an inspection and prepare a
report. Save the container and packing material until contents are verified.
Report the nature and extent of the damage to Customer Support so that action
can be initiated to repair or replace damaged or missing items, or instructions
issued for returning items.
The responsibility of the manufacturer ends at the delivery to the first carrier.ALL
CLAIMS for loss, damage, or nondelivery must be made against the delivering
carrier WITHIN 8 DAYS OF RECEIPT of shipment.
TORETURN THE PRODUCT 1.2
Please obtain instructions from Customer Support before
returning any item(s). Report the fault or deficiency along with the model,
type, and serial number of the item(s) to Customer Support. Upon receipt of this
information, Customer Support will provide service instructions or shipping
information.

CONNECTING THE CONSOLE
MultiCom LAN Access Center — User’s Manual 9
CONNECTING THE CONSOLE 1.3
The console port is used to connect a terminal to your MultiCom. The standard
DB-9 connector for this port is located on the rear panel, as shown in Figure 1.
The pin-out for the console connector is shown in Figure 2. The fifth slot is
reserved for future use and cannot accept standard expansion modules.

CONNECTING THE ETHERNET NETWORK ETHERNET PORTS
MultiCom LAN Access Center — User’s Manual 11
CONNECTING THE ETHERNET NETWORK 1.4
ETHERNET PORTS 1.4.1
The connection to an Ethernet network may be done in two ways:
1. With the RJ-45 connector, to connect directly a Twisted-Pair (10-Base-T)
Ethernet link.
2. With the Adapter Unit Interface (AUI) connector, to connect an adapter to a
Thick (10-Base-5), a Thin (10-Base-2) or an Optical Fiber (10-Base-FL)
Ethernet link.
Figure 4 Ethernet connectors
NOTE - The MultiCom LAN Access Center automatically detects the type of Ether-
net connection used. When both connectors are used, 10-Base-T takes precedence
over AUI. If the 10-Base-T link goes down, the AUI connector will be used
instead, providing backup functionality over AUI.

ETHERNET LEDS1.4.2
• Front-panel Ethernet LED
This LED indicates all Ethernet traffic to and from the MultiCom.
• Rear-panel Link LED
This LED indicates that the Ethernet connection is properly wired. The Link
detection is only possible on the 10-Base-T connector.
• Rear-panel Rx LED
This LED indicates all Ethernet traffic on the connected network.
Figure 5 Rear-panel Ethernet LEDs
WARNING — Do not connect the MultiCom to an ISDN line with any
cable other than the one delivered with the MultiCom. Twisted pair Ether-
net (10-Base-T) cables use the same RJ-45 connectors as ISDN but they
are not compatible. Using the wrong cable or connecting the ISDN port
to an Ethernet Hub may damage the MultiCom.

MultiCom LAN Access Center — User’s Manual 13
INSTALLATION FOR THIN ETHERNET 1.4.3
1. Make sure that your network is functioning without your MultiCom.
2. Plug a Thin Ethernet AUI adaptor into the AUI connector (as shown in Figure
4) of your MultiCom.
3. Connect a “T” connector to the AUI adaptor.
4. Open your network and connect both ends to the “T” connector.

The ports conforms to the EIA 530 Alt A standard. Lightning sells the following
adaptor cables for standard modem interfaces:
These cables are available through your distributor. Please be sure to order the
right cable, corresponding to your modem.
NOTE - Digital modems may require special cables. Contact Lightning’s Tech-
nical Support in that case.

CONNECTING PRI CARDS 1.6
There are two RJ-45 connectors on the PRI card, as can be seen below. The lower
one is the ISDN S2m connector, the upper one is an auxiliary Ethernet port
(reserved for future use).
The PRI LED can be in the following four states:
• Red
This indicates that the ISDN link is not connected or not properly wired.
•Off
This indicates that the ISDN link has been disactivated by the remote switch.
This is rare but may happen with some switches. When needed, the link
should automatically be reactivated.
• Green
This indicates that the ISDN link is OK.
• Orange
This indicates that there is traffic on the D channel.

The BRI LEDs can be in the following four states:
• Red
This indicates that the ISDN link is not connected or not properly wired.
•Off
This indicates that the ISDN link has been disactivated by the remote switch.
When needed, the link should automatically be reactivated.
• Green
This indicates that the ISDN link is OK. It may become red after a certain
time. THIS IS NORMAL . It should become green again, as soon as you
need it.
• Orange
This indicates that there is traffic on the D channel.
