1 Introduction
The rapid development of the computer engineering led in the last years to a
shoot up of electronically transferred data volume. More and more users
want to send and receive more and more data. A demand, that clearly
exceeds the capabilities of past transmission technologies (analog modems
or ISDN devices) .
New technologies compensate these restrictions and offer genuine broad-
band communication with clearly higher data transmission rates. The most
important criterion for the spreading of these new access technologies is the
availability in as much as possible offices or private dwellings. One of the
new technologies is the transmission by means of DSL, using simple copper
wires for the "last mile". A broadband connection to the Internet can be real-
ized also over the domestic cable TV connection.
A LANCOM DSL/I-10 Office or LANCOM DSL/I-1611 Office does function
with nearly each high-speed Internet access based on DSL or cable TV. The
Internet access is always made via an external modem that is connected to
the router.
The most powerful representative in the series, the LANCOM DSL/I-1611
Office, additionally offers the possibility to be used as a VPN gateway.
The smallest member of the LANCOM Office series is the LANCOM 800
Office. This device hasn't got a DSL interface, but possesses all features
which are available for the ISDN interface and which are described in this
manual.
This chapter...
... introduces you briefly to the functions and application fields of routers. You
get an overview of the abilities of your LANCOM Office. You find a detailed
description of the functions, the software and its operation, as well as an
introduction to the technical basics in the following chapters.
1.1 What does a router do?
Routers connect Local Networks (LANs) and individual PCs to form a Wide
Area Network (WAN). In this WAN each computer can access (depending on
its rights) the other computers and services of the complete WAN. The router
thereby searches a way on which the data between the computers can be
exchanged.
Introduction

LANCOM Office

EN
This is available e.g. with LANCOM DSL/I-1611 Office and LANCOM DSL/I-10
Office in form of a DSL connection, which is realized via conventional copper
telephone lines. Furthermore, an ISDN connection with an adequate ISDN
router is available then, as well as LANCAPI functions and dial-back up for
the Internet connection.
With these features a LANCOM Office is ideally suited in particular for the
use with high-speed Internet connections. All workstations in the local net-
work of a company can access and use the services and contents of the World
Wide Web if the LAN is connected to the network of an Internet service pro-
vider
The router is integrated into the LAN like a conventional PC. All data, which
flows through the wiring of the network, reaches also the router. The router
decides independently then whether particular data must be transferred into
another network or not.
1.2 Typical applications
1.2.1 Internet in the LAN
In many enterprises grows the demand for an access to the Internet from all
workstations of the LAN. Online searches, e-mail and file transfer are only
some applications, which facilitate the PC-based work for the users.

The router links all the workstation computers on your local area network to
the global Internet. Security functions such as IP Masquerading and Firewall
filters protect your LAN against unauthorized access from outside.
1.2.2 LAN to LAN coupling
If the business runs correctly, soon it becomes time for a subsidiary or a
branch office in the global markets. Also the branch has its own network and
would like to be always up to date.
The LAN to LAN coupling links individual LANs to form one large network,
even if this means crossing continents. Using connections via switched lines,
an intelligent line management in interaction with sophisticated filter mech-
anisms ensures small connecting costs.
Faster, more economically and more flexibly is the network coupling via Inter-
net. Here the broadband access to the Internet comes into play (via DSL or
the cable TV network). LAN to LAN couplings via the Internet take place as
Virtual Private Networks (VPN).
LANCOM DSL/I-1611 Office can be upgraded with the LANCOM VPN Option
and supports the set-up of VPNs then.
1.2.3 Homeworking with Remote Access
The work of many office workers in modern organizations is less and less
dependent on any definite location - the most important factor is unimpaired
access to shared and freely available information.
Remote Access (RAS) is the magic word here. Employees working from home
or field staff can dial into the company network via ISDN. When working with
remote access, LANCOM Office protects the company network: the callback
function only grants access to known and registered users. And for a more
comfortable settlement of accounts, the connecting costs are centrally regis-
tered in the company.
All devices of the LANCOM Office series support remote access services via
ISDN. Optionally, the LANCOM DSL/I-1611 Office supports VPN-based RAS
as well.

1.2.4 Office communications
Faxing directly from within applications, voice mail with different announce-
ments according to the time of day, banking without having to leave the
office: These functions can be enabled by using LANCAPI.
The LANCAPI is a special type of CAPI-2.0 interface that permits appropriate
applications to access the router.
All LANCOM Office enable office communication functions via their ISDN
interface.
1.3 What can your LANCOM Office do?
The following section provides a brief overview of the most important fea-
tures of your device.
1.3.1 All devices of the LANCOM Office series
Simple Installation
• Power supply to LANCOM Office
• Establishing connection to the LAN
• Establishing connection to DSL or cable modem (not LANCOM 800 Office)
• Connecting ISDN cable
• Switch on
• Installation of LANCOM software and basic configuration with the com-
fortable wizards
• Go!
LAN connection
You link a LANCOM router with its 10/100Base-T connector to an (Fast) Eth-
ernet. The connector checks automatically the operation speed of the local
area network.
WAN connection
LANCOM DSL/I-10 Office and LANCOM DSL/I-1611 Office are connected to
the Ethernet interface of a DSL or cable modem.
ForLANCOM 800 Office, the ISDN interface is available as WAN connector.
|
Introduction

|
LANCOM Office
|
EN
LANCOM DSL/I-1611 Office and LANCOM DSL/I-10 Office have got an addi-
tional ISDN connector, which is linked to the S
0
port(s) of an ISDN
point-to-multipoint connection (point-to-multipoint configuration) or a
point-to-point connection (point-to-point configuration). The router automati-
cally detects your port type and D-channel protocol in use.
IP-Routing: connection establishing and administration
The router checks all IP packets in the network whether they have to be sent
to another network or computer. If a transfer is necessary, the router estab-
lishes the connection itself and closes the connection once the transfer is
completed.
Security features
A LANCOM Office has powerful security functions to prevent unauthorized
access to your company network from outside. IP masquerading hides all
workstations of a LAN behind a single public IP address. The actual identities
(IP addresses) remain concealed. Firewall filters allow specific IP addresses,
protocols and ports to be blocked. MAC address filters enable control of
access for specific workstations to the IP routing functions of the device.
Login barring prevents any "brute force attacks" and denies access to the
router after a configurable number of login attempts using an incorrect pass-
word. This measure effectively protects the configuration of the router
against repeated attacks.
DHCP
Your LANCOM Office features the following DHCP modes:
• DHCP server to assign the IP addresses
• DHCP relay agent to forward DHCP inquiries
Your device works already with the presetting in an ingenious automatic
DHCP mode, so that the setting-up of a LANCOM Office becomes easy both
in an existing and in a new network, regardless of its DHCP settings.
DNS server
The built-in DNS server of the router creates links between IP addresses and
names of computers or networks. In case of inquiries for known computer
names, the correct route can be assigned directly then .
Thereby, the DNS server can make use of the names and IP information pro-
vided both from the DHCP server and from the NetBIOS module.

The DNS server can be used also as an effective filter for users in the own
LAN. For individual computers or entire networks the access to certain
domains can be blocked.
Virtual Private Network (VPN)
Your LANCOM DSL/I-1611 Office can be upgraded with the VPN option to a
full-featured VPN gateway (according to the IPSec standard). This enables to
establish secure network couplings to other VPN gateways via the Internet
(or other IP networks). The IPSec standard and most recent encoding tech-
niques ensure a high safety level of the VPN connections.
LANmonitor
With LANmonitor you have under Windows operating systems all router's
status information always on the screen. For each device of the local area
network the most important information is provided, e.g.:
• Connecting state for each transfer channel
• Name of the connected remote station
• Which module from the device is connected? (Router, LANCAPI)
• Connecting time and data transmission rates
• Excerpts from the statistics of the device (e.g. information from the PPP
negotiation).
Beyond that, the software supports logging and storage of output for later
purposes on the PC.
Status displays
LED status information on the front panel of your device provide a quick check
of all LAN and WAN connections and facilitate the diagnosis of potential sys-
tem troubles.
Configuration
Setting up and configuring the device to your specific requirements is made
quick and easy by the included configuration tool LANconfig for Windows
operating systems.
For Linux exists a beta version of xLANconfig which you can find on the LAN-
COM CD or download in the current version from the download area of the
LANCOM website.

Users of other operating systems than Windows may employ the
HTML-based configuration with WEBconfig, a SNMP management system,
Telnet or any terminal program.
The access to the device is possible from the LAN, from WAN, by remote con-
figuration via ISDN dial-in, or directly through the integrated serial configu-
ration interface.
The integrated setup wizards of LANconfig and WEBconfig help you to set up
the devices in a few steps.
Firmware update
In order to preserve always an up to date software version, all devices have
got an internal Flash ROM memory.Thus a new firmware can be downloaded
very comfortably, and it is not necessary to open your device.
The current firmware version is always available via the LANCOM hompage.
It can be uploaded to the device through the LAN or WAN interface, via ISDN
or through the serial configuration interface.
LANCOM FirmSafe
There is no risk involved in uploading a new firmware: The LANCOM FirmSafe
function enables two firmware files being preserved on one device. If the
new firmware version does not function as desired after the upload, you can
simply revert to the previous version.
If you encounter an error during the upload (e.g. caused by a transmission
error), the device reverts automatically to the working previous version.
Connect charge protection
The connect charges for the Internet use are calculated time-dependent,
according to your Provider. For not being surprised by a high invoice at the end
of the month, you can specify in advance how many online minutes for the
Internet connection should be permitted over a LANCOM Office in a certain
period (e.g. 600 minutes in 6 days).
Statistics
The extensive statistics provide control of your LANCOM Office at any time .
For example, you find information about all transmitted data packets in order
to optimize the configuration of your device.

1.3.2 Additional functions of the ISDN interface
All LANCOM Office provide an ISDN connector, which offers some additional
functions.
Multiprotocol router
Via the ISDN interface other protocols than IP can be routed also . For exam-
ple, the IPX protocol enables the coupling of Novell networks.
LANCOM router offer a special feature for the interconnection of Microsoft
peer-to-peer networks. With the integrated routing of NetBIOS/IP packets,
the linking of Windows networks becomes a simple task. The remote stations
with which NetBIOS information have to be exchanged are registered in a
special list in order to avoid that each NetBIOS packet triggers a connection.
Acting as a NetBIOS proxy then, the router answers all inquiries regarding
known computers locally, and avoids in this way an unnecessary establish-
ment of connections.
Compatibility by PPP
The router supports communication with products of other vendors. Espe-
cially PPP is a very widespread protocol for the interchange of network data
via point-to-point connections.
Remote configuration using PPP
A special configuration highlight of LANCOM is the PPP-based remote man-
agement for routers, which cannot and should not be set up locally. A new
device has just to be supplied with voltage and to be connected with its WAN
interface. Then you can dial-in to the router simply over a PPP connection and
configure it comfortably from your specific remote location. This access is
protected by a password after the initial configuration and remains locked for
unauthorized callers.
Security features for the ISDN interface
To secure the integrated ISDN interface, the LANCOM Office uses password
protection and caller identification (CLI), as well as the callback function to
restrict connection establishment to previously specified ISDN subscriber
numbers. Furthermore, additional PPP authentication mechanisms enhance
the security concept.

Optional LANCOM Dynamic VPN
With the LANCOM VPN Option a LANCOM DSL/I-1611 Office is enabled to
set up VPN tunnels even between two peers with both dynamic IP addresses.
This is enabled by the patent-pending LANCOM Dynamic VPN technology.
LANCOM LANCAPI and LANCOM CAPI Faxmodem
The main advantages of using LANCAPI are economic ones: LANCAPI is a
special implementation of the CAPI 2.0 interface that permits different com-
munication programs to access a router via the network.
By LANCAPI, all workstations that are part of a LAN get an unrestricted
access to office communication functions such as fax and eurofile transfer.
All functions are available via the network, without additional hardware at
the workstations. This eliminates the costs of equipping all individual work-
stations with ISDN adapters or modems. Solely the software for office com-
munication has to be installed at each workstation (if not already provided by
the operating system).
A fax device is simulated at the workstation so that faxes can be sent. With
LANCAPI, the PC forwards the fax via the network to the router, which estab-
lishes the connection to the recipient then.
Automatic time control
The device needs always the exact time in order to provide meaningful sta-
tistics and to choice the right connection via the least-cost-router . The device
itself can read the time via the ISDN network or via public NTP time servers.
The internal time of the router is compared either with each connection
establishment or with each switch-on of the device with the external time
service. A manual setting of the time is also possible, of course.
Channel bundling and compression
The device supports on the ISDN line both static and dynamic channel bun-
dling via MLPPP and BACP. Stac data compression (hi/fn) can be used to
achieve an additional increase of the data transfer rate up to 400%.
Least-cost-routing
Also with a considerable large number of providers for telecommunication
services, you always select the most inexpensive ISDN lines with the
least-cost-router. Thereby you define once the provider with the most favor-
able rates for your needs and by each connection, the router selects automat-

ically the provider with the most favorable rates (no matter, if via the router
or via LANCAPI).
Leased line option
The network coupling via ISDN leased lines is possible with the optional
leased line option.

3.3 Hardware installation
a Connect your LANCOM Office to the LAN. Plug the supplied network
cable (green plugs) into the 10/100Base-Tx connection of the device 4
and into a free connector socket of your local network (resp. a free socket
of a hub or switch in your LAN). It is also possible to connect an individual
PC. In this case, you turn the node/hub switch 5 on 'hub'.
b Connect your LANCOM Office to ISDN. Plug one end of the supplied ISDN
connector cable (light blue plugs) in the ISDN S
0
port 7 of the device and
the other end into an ISDN S
0

LED will be permanently lit. The LED ’LAN-Link’ indicates a correct con-
nection to the LAN.
If the ’LAN Link’ LED does not light, please actuate the Node/Hub switch 5
on the back of the unit. If the LED still does not light, there might be a problem
with the network or cable installation.
3.4 Software installation
This section covers the installation of the included LANCOM software for
Windows. If you use your LANCOM Office exclusively with computers run-
ning operating systems other than Windows, you may skip this section. A
software installation is not necessary in this case.
A Windows operating system is required for a few functions of your router.
Among these functions is the monitoring with LANmonitor. The LANCAPI
functions of the LANCOM Office require also a Windows operating system
for the ISDN interface at your working place PCs.
3.4.1 Starting LANCOM setup
Place the LANCOM CD in your CD drive. The setup program will start auto-
matically.
If the setup program does not start automatically, run AUTORUN.EXE in the
root folder of the CD.
In Setup select Install LANCOM software. The following selection menus
will appear on the screen:

3.4.2 Which software should you install?
Select the required software for the operation of your LANCOM Office:
• LANconfig is the configuration program for all LANCOM. WEBconfig
can be used alternatively (or in addition) via a web browser.
• LANmonitor lets you monitor all LANCOM in the LAN.
• LANCAPI can be installed on as many Windows PCs in the LAN as
required, permitting them to run any ISDN software. A PC with LANCAPI
behaves as if it had its own ISDN card. In actual fact, the ISDN connec-
tion is realized centrally using the LANCOM with its ISDN interface.
• LANCAPI Dial-up Networking Support lets you use the CAPI soft-
ware interface on your Windows PC as a network adapter, for example
for dial-up remote access to an LANCOM.
• The LANCOM CAPI Faxmodem installs a fax modem driver on your
Windows PC, permitting you to send faxes via the LANCAPI.
Select the appropriate software options and confirm with Next. The soft-
ware is automatically installed.
3.5 In the next chapter …
… we will perform the basic configuration of your device. Only with a few
mouse clicks you will configure your LANCOM Office such as all PCs in the
LAN have got an Internet access with highest speed.

4 Basic configuration
In this chapter we will explain the basic configuration of your LANCOM
Office:
• Assignment of a free IP address
• Activation of the integrated DHCP server (if desired)
• Protection of the configuration access by password
• Configuration of the ISDN interface
• Setting up an Internet access
4.1 Starting the setup wizard
Any unconfigured LANCOM Office can be accessed in two comfortable ways:
• LANconfig will automatically find any unconfigured LANCOM and will
start the setup wizard for its basic configuration automatically.
• With WEBconfig: Enter IP address of the unconfigured LANCOM Office at
any PC of the connected network in the address field of a web browser.
In certain network environments you can access your LANCOM Office
also with the input of any name in the address field. See ’What is the IP
address of the LANCOM Office?’ on page 28.
You should never have more than one unconfigured LANCOM in a network
segment at any given time, since all unconfigured LANCOM devices use the
same IP address (with final digits '254'), which would result in an address
conflict then. To avoid such problems, always configure multiple LANCOM
devices one after the other, immediately assigning unique IP addresses.
4.1.1 Basic configuration with LANconfig
a Start up LANconfig by clicking Start / Programs / LANCOM / LANcon-
fig.
LANconfig automatically detects the new LANCOM Office in the TCP/IP
network. Then the setup wizard starts that will help you making the basic
settings of the device or will even do all the work for you (provided a suit-
able network environment exists).

If the setup wizard does not start automatically, start a manual search for
new devices in the network (Device / Find).
This input window appears only, when no DHCP server is active in your
network and your PC has also got no manually assigned IP address. Oth-
erwise the wizard goes on as described under b for the input 'I wish to
define the settings myself'.
Make your selection after the following considerations:
Select ’All settings to be defined automatically’ …
… if you are not familiar with networks and IP addresses and you have
not been used any IP addresses in your network so far. Then the router as
DHCP server will automatically specify and assign the IP addresses for all
devices in the LAN.
Select ’I wish to define the settings myself’ …
… if you are familiar with networks and IP addresses, and one of the fol-
lowing conditions is applicable:
• You have not yet used IP addresses in your network but would like to
do so now. You would like to specify the IP address for your router,
selecting it from the address range reserved for private use, e.g.
'10.0.0.1' with the netmask '255.255.255.0'. At the same time you will
set the address range that the DHCP server uses for the other devices
in the network (provided that the DHCP server is switched on).
• You have previously used IP addresses for the computers in your LAN.

b If you would like to configure the TCP/IP settings manually, assign an
available address from a suitable address range to the LANCOM Office.
Confirm your choice with Next.
c Specify whether or not the router should act as a DHCP server. Make your
selection and confirm with Next.
d In the following window, specify the password for configuration access.
In addition, you may specify whether the device may only be configured
from the local network, or whether remote configuration via the WAN
and/or via ISDN is also permissible. Confirm your choice with Next.
Please note that enabling this will also permit remote configuration via
the Internet. You should always make sure that the configuration access
is protected with a password.
e Now configure the ISDN interface. Confirm your choice with Next.
f If you would like to configure the ISDN settings for your LANCOM Office,
enter the subscriber number (as MSN, i.e. without area code) on which
the router will accept calls. In addition, you can enter a trunk code for
dialing into ISDN. Finally, you should specify whether or not the tariff
information is to be transmitted at your ISDN connection. Confirm your
choice with Next.
g Complete the configuration with Finish.
4.1.2 4.1.2 Basic configuration with WEBconfig
As you know, it is possible to configurate with WEBconfig your LANCOM
Office with any web browser. So you are not dependent on the operating sys-
tem Windows as with LANconfig.
The only precondition: You must know how to address the unconfigured
router in the LAN. An unconfigured LANCOM always reacts to a certain IP
address, and in some network configurations even to a name.
Does my LANCOM Office react to a name?
If you do not yet have a DHCP or DNS server on your LAN, the router reacts
to any name (like 'LANCOM' or 'Router') that you specify in the URL address
field of a web browser.
If you don't know whether IP addresses have been used in your network up
until now, display the IP address of your own PC (see the following section).
Basic configuration

If the 'IP Address' field contains the value '0.0.0.0', this indicates that an IP
address has not yet been assigned to the network card.
What is the IP address of the LANCOM Office?
The IP address of an unconfigured LANCOM results from the IP address of
your PC by replacing the last number of its IP address (behind the third dot)
with 254.
For example, if your PC is assigned the IP address 10.0.0.17, then you will find
an unconfigured LANCOM under the address 10.0.0.254. The IP address of
your PC can be displayed (depending on the operating system) with the fol-
lowing command line commands (entry under Windows at the command
prompt):
Starting the wizards in WEBconfig
a Start your web browser (e.g. Internet Explorer, Netscape Navigator) and
call the LANCOM Office there:

5 Setting up Internet access
All computers in the LAN can take advantage of the central Internet access
of the LANCOM Office. The connection to the Internet provider can be estab-
lished via any WAN connection, i.e. not only via DSL (if present), but also via
ISDN. Internet access via ISDN can be used as a backup connection for DSL,
for example.
Does the setup wizard know your Internet provider?
A convenient wizard is available to help you set up Internet access. The wiz-
ard knows the access information of major Internet providers and will offer
you a list of providers to choose from. If you find your Internet service provider
on this list, you normally will not have to enter any further transfer parame-
ters to configure your Internet access. Only the authentication data that are
supplied by your provider are required.
Additional information for unknown Internet providers
If the setup wizard does not know your Internet provider, it will prompt you
for all of the required information step by step. Your provider will supply this
information.
Additional connection options
You may also enable or disable further options in the wizard, depending on
whether or not they are supported by your Internet provider:
• Time-based billing or flat rate - select the accounting model used
by your Internet provider.

• When using time-based billing, you can set the LANCOM Office to
automatically close existing connections if no data has been trans-
ferred within a specified time (the so-called idle time).
In addition, you can activate a line monitor that identifies inactive
remote stations faster and therefore can close the connection before
the idle time has elapsed.
• Active line monitoring can also be used with flat rate billing to con-
tinuously check the function of the remote station.
You also have the option of keeping flat rate connections alive if
required. Dropped connections are then automatically reestablished.
• Dynamic channel bundling (ISDN only)
• If required, the second ISDN B channel will automatically be bundled
to the connection. This doubles the available bandwidth; but it may
also double your connect charges as well. What's more, your ISDN
connection will be busy in this case, with all other incoming and out-
going calls being rejected.
• Data compression (ISDN only)
• This permits an additional increase in data throughput.

Linking two networks

LANCOM Office

6 Linking two networks
With the network interconnection (also known as LAN to LAN coupling) of the
LANCOM Office, two local networks are linked via ISDN. A setup wizard han-
dles the configuration of the connection in the usual convenient manner.
Always configure both sides
Both routers involved in the network interconnection must be configured.
Care must be taken to ensure that the configuration information provided
matches.
The following instructions will assume that LANCOM routers are being used
on both sides. A network interconnection may also be realized with routers
from other manufacturers. A mixed setup usually requires more extensive
configuration measures for both devices, however. Please refer to the LAN-
COM reference manual for more information in this regard.
Security aspects
You must, of course, protect your LAN against unauthorized access. A LAN-
COM Office therefore offers a whole range of security mechanisms that can
provide an outstanding level of protection:
• Password-protected connections – simple and effective security.
• Verification of the ISDN subscriber number – for additional security.
• Callback function – for the highest security. Instruct the router to call
incoming callers back under their own numbers.
The callback function cannot be configured using the wizard. It can only be
set up in the expert configuration. For details, please see the LANCOM refer-
ence manual.
High-speed network links via DSL—VPN is the answer
To couple LANs using a fast DSL connection, you need the LANCOM VPN Option. This soft-
ware option enables your LANCOM DSL/I-1611 Office router as a fully-fledged VPN gate-
way. Two LANCOM routers with LANCOM VPN Option can be deployed to link LANs via the
Internet.
The setup and configuration of VPN connections are covered in the LANCOM VPN Option

6.1 What information is necessary?
The wizard will prompt you for the necessary information on a step-by-step
basis. If possible, however, you should have it available before launching the
wizard.
To explain the significance of the information requested by the wizard, we
will be using a typical deployment as an example: setting up a link between
a branch office and its headquarters. The routers involved are named
'HEAD_OFFICE' and 'BRANCH'.
Please refer to the following tables for the entries to be made for each of the
routers. Arrows mark the dependencies between the entries.
6.1.1 General information
Name of local device and of remote station
If you haven't already named your LANCOM, the wizard will ask you for a
new, unique device name. With this entry, you will rename your LANCOM.
Be sure to give the two devices different names.
The name of the remote station is necessary for its identification.
Connection information
Enter the subscriber number of the remote station in the ISDN subscriber
number field. The complete subscriber number including all necessary area
and country codes is required.
The stated ISDN caller ID is used to identify and authenticate callers. When
a LANCOM receives a call, it compares the ISDN caller ID entered for the
Settings of the router in the ... Head Office Branch
Name of the local device 'HEAD OFFICE' 'BRANCH'
Name of the remote station 'BRANCH' 'HEAD OFFICE'

remote station with the actual caller ID transferred via the D channel. An
ISDN caller ID generally consists of an area code and an MSN.
The password for the ISDN connection is an alternative to the use of the
ISDN caller ID. It is always used to authenticate callers that do not send an
ISDN caller ID. The exact same password must be entered on both sides. It is
used for calls in both directions.
Data compression and Channel bundling
Data compression increases the transfer speed of the connection at no addi-
tional cost. This is completely unlike the bundling of two ISDN channels with
MLPPP (MultiLink PPP): The transfer rate will be doubled but there will also
be additional telephone costs for two connections.
Selection of network protocols
Select the desired network protocols:
• TCP/IP - for example for Internet, intranet, Windows, Unix. NetBIOS can
also be selected for Windows peer-to-peer networks.
• IPX - for Novell networks
6.1.2 Settings for the TCP/IP router
In TCP/IP networks, addressing has a special significance. Please note that
two interconnected networks are logically separate from one another. Each
must therefore have its own network number (in our example, '10.0.1.x' and
'10.0.2.x'). These network numbers may not be identical.

Unlike when accessing the Internet, all of the IP addresses in the involved
networks are visible on the remote side when coupling networks, not just
those of the router. The computer with the IP address 10.0.2.10 in the branch
office LAN sees the server 10.0.1.2 in the headquarters and can access it
(assuming it has the appropriate rights), and vice versa.
DNS access to the remote LAN
Thanks to DNS, it is not only possible to access remote computers in a TCP/
IP network via their IP address, but also by using freely defined names.
For example, the computer with the name 'pc1.branch.company' (IP 10.0.2.10)
will not only be able to access the server of the head office via its IP address,
but also via its name, 'server.head.company'. The only precondition: the
domain of the remote network in the wizard must be specified.
The domain can only be specified in the LANconfig wizard. In WEBconfig,
enter the appropriate information later in the expert configuration. For more
information, see the LANCOM reference manual.
6.1.3 Settings for the IPX router
Coupling two typical IPX networks to form a WAN requires three IPX network
numbers:
LAN of the head office. IP:
10.0.1.0, netmask: 255.255.255.0
Domain: 'head.company'
10.0.1.100
(0123) 123456

• for the LAN of the head office
• for the LAN of the branch office
• for the higher-level WAN
The IPX network numbers in the head and branch offices are specified to the
respective remote sides.
The three required network numbers are designated as "External Network
Numbers" by the IPX conventions. Like IP network addresses, the apply to an
entire LAN segment. On the other hand, internal IPX numbers are used to
address specific Novell servers in the LAN. All three specified network num-
bers must be distinct from one another and from all used internal IPX network
numbers.
In addition, it may be necessary to enter the frame type ("binding").
Specifying the IPX network number and binding used is not necessary if the
remote network also contains a Novell server. It is only necessary to enter the
network number for the WAN manually in this case.
6.1.4 Settings for NetBIOS routing
NetBIOS routing can be set up quickly: All that is required in addition to the
information for the TCP/IP protocol used is the name of a Windows work-
group from in the router's own LAN.
Remote Windows workgroups do not appear in the Windows Network Neigh-
borhood, but can only be contacted directly (e.g. via Find Computers).

To test a TCP/IP connection, simply send a
ping
from your computer to a computer in the
remote network. For more information on the 'ping' command, please see the documentation
of your operating system.
IPX and NetBIOS connections
can be tested by searching for a
remote Novell server or a com-
puter in the remote Windows
workgroup from your computer.

7 Providing dial-up access
Your LANCOM Office supports dial-up connections to permit individual com-
puters full access to your network. This service is also known as RAS (Remote
Access Service).
The physical connection is realized via ISDN. An ISDN adapter or ISDN
modem is therefore the only hardware requirement for the PC. PPP is used as
the data transfer protocol. This ensures that all common devices and operat-
ing systems are supported.
A setup wizard handles the configuration of the dial-up connection in the
usual convenient manner.
Security aspects
You must, of course, protect your LAN against unauthorized access. A LAN-
COM Office therefore offers a whole range of security mechanisms that can
provide an outstanding level of protection:
• Password-protected connections - simple and effective security.
• Verification of the ISDN subscriber number - for increased security.
• Callback function - the highest security levels can be achieved by setting
the router to call participants back at a number specified earlier.
The callback function cannot be configured using the wizard. It can only be
set up in the expert configuration. For details, please see the LANCOM refer-
ence manual.
7.1 Which information is required?
The wizard will set up dial-up access for only one user. Please run the wizard
again for each additional user.
User name and password
Users authenticate themselves with this information when dialing in.
Incoming number
The LANCOM Office uses the optional ISDN caller ID as an additional user
authentication. This security function should not be used when users dial in
from differing locations.

Selection of network protocols
Select the desired network protocols:
• TCP/IP - for example for Internet, intranet, Windows, Unix. NetBIOS can
also be selected for Windows peer-to-peer networks.
• IPX - for Novell networks
Important for TCP/IP: One IP address
Each active RAS user must be assigned an IP address when using the TCP/IP
protocol. This IP address can be permanently assigned when setting up a
user. However, it is simpler to let the LANCOM Office automatically assign
free IP addresses to users when they dial in. In this case you only need to
specify the IP address range that the LANCOM Office should use for RAS
users..
During both manual and automatic IP address assignment, please ensure that
only free addresses from the address range of your local network are used. In
our example, the IP address '10.0.1.101' will be assigned to the PC when con-
necting.

The ISDN calling line identity (CLI)
The ISDN caller ID—also known as CLI (Calling Line Identity)—this is the telephone number
of the caller which is transmitted to the participant receiving the call. As a rule, it consists
of the country and area codes and an MSN.
The CLI is well-suited for authentication purposes for two reasons: it is very difficult to
manipulate, and the number is transferred free of charge via the ISDN control channel (D
channel).

This IP address makes the computer a fully-fledged member of the LAN: with
the appropriate rights, it can access all of the other devices in the LAN. The
same applies in the other direction as well: computers in the LAN will also be
able to access the remote machine.
Settings for IPX
Two IPX network numbers must be provided for remote access to an IPX net-
work:
• the IPX network number of the head office
• an additional IPX network number for the higher-level WAN
The required network numbers are designated as "External Network Num-
bers". Like IP network addresses, they apply to an entire LAN segment. On the
other hand, internal IPX numbers are used to address specific Novell servers
in the LAN. All three specified network numbers must be distinct from one
another and from all used internal IPX network numbers.
In addition, it may be necessary to enter the frame type ("binding").
Specifying the IPX network number and binding used is not necessary if the
remote network also contains a Novell server. A network number for the
WAN must also be entered manually in this case, however.
Settings for NetBIOS routing
All that is required to use NetBIOS is the name of a Windows workgroup from
the router's own LAN.

The connection is not established automatically. The RAS user must manually
establish a connection to the LANCOM Office via Dial-Up Networking first.
When connected, they can search for and access computers in the remote
network (via Find / Computers, not through the Network Neighborhood).
7.2 Settings for the dial-in computer
A number of settings must be configured on the dial-in computer. These are
briefly listed here, based on a Windows computer:
• Dial-Up Networking (or another PPP client) must be correctly configured
• Network protocol (TCP/IP, IPX) installed and bound to the dial-up adapter
• New connection in Dial-Up Networking with the call number of the router
• Terminal adapter or ISDN card set to PPPHDLC
• PPP selected as the Dial-Up server type, 'Enable software compression'
and 'Require data encryption' unchecked
• Select desired network protocols (TCP/IP, IPX)
• Additional TCP/IP settings:
• Assignment of IP address and name server address enabled
• 'IP header compression' disabled
These settings will permit a PC to dial into a remote LAN via ISDN and access
its resources in the usual manner.

8 Office communications with the LAN-
CAPI
LANCAPI from LANCOM Systems is a special version of the popular CAPI
interface. CAPI (Common ISDN Application Programming Interface) estab-
lishes the connection between ISDN adapters and communications pro-
grams. For their part, these programs provide the computers with office com-
munications functions such as a fax machine or answering machine.
In this chapter, we would like to introduce LANCAPI and its uses for office
communications applications.
8.1 What are the advantages of LANCAPI?
The main advantages of using LANCAPI are economic. LANCAPI provides all
Windows workstations integrated in the LAN with unlimited access to office
communications functions such as fax machines, answering machines, online
banking and eurofile transfer. All functions are supplied via the network with-
out the necessity of additional hardware at each individual workstation. This
eliminates the costs of equipping the workstations with ISDN adapters or
modems. All you need to do is to install the office communications software
on the individual workstations.
For example, faxes are sent by simulating a fax machine at the workstation.
With LANCAPI, the PC forwards the fax via the network to the router which
establishes the connection to the recipient.
All applications that you run via LANCAPI use direct ISDN connections which
do not make use of the device's router functions. As a result, the firewall and
charge monitoring functions do not work!
The client-server principle
The LANCAPI is made up of two components, a server (in the LANCOM Office)
and a client (on the PCs). The LANCAPI client should only be installed on the
computers of the local network that intend to use the functions of the LAN-
CAPI.
8.2 Configuring the LANCAPI server
Two basic issues are important when configuring the LANCAPI server:
|

|
LANCOM Office
|
EN
• What call numbers from the telephone network should LANCAPI respond
to?
• Which of the computers in the local network should be able to access the
telephone network via LANCAPI?
The configuration of the router is performed using the LANconfig or WEBcon-
fig configuration tables. The following two sections contain step-by-step
instructions for each of these configuration programs.
8.2.1 Instructions for LANconfig
a Doubleclick the device name in the list to open the configuration of the
router and enter your password when prompted to do so.
b Select the LANCAPI configuration section.
Double-click the list entry

c Select the ISDN interface.
d Activate the LANCAPI server for the outgoing and incoming calls, or allow
only outgoing calls.
If you would like the LANCAPI server to accept incoming calls, enter all
of the MSNs on which the LANCAPI should answer calls in the 'Number
(MSN/EAZ)' field. Use semicolons to separate multiple numbers. If you do
not enter a subscriber number here, the LANCAPI will answer all incom-
ing calls on the local ISDN connection.
8.2.2 Instructions for WEBconfig
a In the main menu, select Expert Configuration.
b In the following menus, select Setup / LANCAPI Module / Interface-
list.
c In the Interface-list, select the only entry, S0-1.

d Activate the LANCAPI server for the outgoing and incoming calls ('On'), or
allow only outgoing calls ('Out').
If you would like the LANCAPI server to accept incoming calls, enter all
of the MSNs on which the LANCAPI should answer calls in the 'Sub-
scriber Numbers (MSN/EAZ)' field. Use semicolons to separate multiple
numbers. If you do not enter a subscriber number here, the LANCAPI will
answer all incoming calls on the local ISDN connection. Confirm your
entries with Apply.
8.3 Installing the LANCAPI client
You must have administrator rights to install the LANCAPI client on a system
running Windows XP or Windows 2000.
a Place the LANCOM CD in the CD-ROM drive of the client PC. If the setup
program does not automatically start when you insert the CD, simply click
'autorun.exe' in the main directory of the LANCOM CD in the Windows
Explorer.
b Select the Install LANCOM software entry.
c Highlight the LANCAPI option. Click Next and follow the instructions for
the installation routine. Finally, restart the computer if required.
The LANCAPI client will start automatically from now on. Its status is dis-
played by the new icon in the Windows system tray (next to the clock).

8.4 Configuration of the LANCAPI client
The configuration of the LANCAPI client is used to determine which LANCAPI
servers will be used and how these will be checked. All parameters can
remain at their default settings if you are using only one LANCOM in your
LAN as a LANCAPI server.
a Start the LANCAPI client in the 'LANCOM' program group. Information
regarding the drivers and the available service can be found on the 'Gen-
eral' tab.
b In the LANCAPI client, change to the Network tab. First, select whether
the PC should find its own LANCAPI server, or specify the use of a partic-
ular server.
• For the former, determine the interval at which the client should
search for a server. It will continue searching until it has found the
number of servers specified in the next field. Once the required num-
ber of servers has been found, it will stop searching.
• In the event that the client should not automatically search for serv-
ers, list the IP addresses of the servers to be used by the client. This
can be useful if you are operating several LANCOM in your LAN as
LANCAPI servers and you would like to specify a server for a group of
PCs, for example.
• It is also possible to set the interval at which the client checks
whether the found or listed servers are still active.
Quick access to the LANCAPI client
There are two ways to launch the LANCAPI client directly from the Windows taskbar: Dou-
ble-clicking the icon will open the status window, from which you can reach the configura-
tion via Properties.
A right-click will take you to the client even faster. Select
Properties from the context menu.

8.5 How to use the LANCAPI
Two options are available for the use of the LANCAPI:
• You may use software which interacts directly with a CAPI (in this case,
the LANCAPI) port, such as RVS-COM. This type of software searches for
the CAPI during its installation and uses it automatically.
• Other programs such as LapLink can establish a variety of connection
types, for example, using Windows Dial-Up Networking. You may select
the installed communications device that you would like to use when cre-
ating a new dial-up connection. For the LANCAPI, select the entry 'ISDN
WAN Line 1'.
8.6 The CAPI Faxmodem
The CAPI Faxmodem provides a Windows fax driver (Fax Class 1) as an inter-
face between the LANCAPI and applications, permitting the use of standard
fax programs with an LANCOM Office.
