Figure 1: Office to Internet
Both ISDN Access Server models include a built-in 4 port
10BaseT hub, allowing you to easily create a peer-to-peer
network.
They also include two (2) analog ports, allowing you to connect an analog (POTS) telephone, answering machine, or fax.
1
ISDN Access Server User Guide
For added versatility, the ISDN Access Server IAS-2410
includes a printer port, allowing LAN users to share the
attached printer.
ISDN Access Server Features
The ISDN Access Server incorporates many advanced features,
carefully designed to provided sophisticated functions while
being easy to use.
LAN Features
Ø Built-in Hub. The built-in 4-port hub saves the cost and
additional wiring of a separate hub.
Ø Hassle-free LAN Installation. Just plug it in, whether
or not you wish to use the built-in hub.
Ø DHCP Server Support. Dynamic Host Configuration
Protocol provides a dynamic IP address to PCs and other
devices upon request.
The ISDN Access Server can act as a DHCP Server.
Ø Multi Segment LAN Support. If you have a Router,
PCs on other LAN segments can use the ISDN Access
Server to access the Internet and, on the IAS-2410, share
the printer.
Internet Access Features
Ø Shared Internet Account. All users on the LAN can
share the same Internet Account.
Ø Additional Bandwidth via Serial Port. If, in the
future, the ISDN link provides insufficient bandwidth, you
2
About your ISDN Access Server
can connect a modem or ISDN TA to the serial port to
provide increased bandwidth.
Ø Dial-On-Demand & Auto-Disconnect. A connection
is established to the Internet as required, and automatically disconnected when no longer needed. This reduces
on-line charges to the minimum possible level.
Ø PPP Authentication. This is used to validate the log-on
to your Internet Service Provider.
ISDN Features
Ø Easy Configuration. No complex technical data or
unintelligible prompts. You’ll be finished in minutes!
Ø Intelligent B Channel Utilization. Internet access will
automatically switch between 1 or 2 B channels, depending on the volume of data.
Ø Outgoing call ID. The ISDN Access Server supports
Outgoing call ID for both MSN (Multiple Subscriber
Numbering) and SAD (Sub Address).
Ø Analog Ports. Two (2) analog ports are provided, to
allow connection of your existing analog telephone, answering machine, or fax.
Ø Analog Call Priority. If both B channels are in use, one
channel will be disconnected when an incoming call is
detected, or you wish to make an outgoing call.
Printer Sharing Features
Ø LAN Printer Sharing. Users on the LAN can share the
printer attached to the ISDN Access Server. All they need
ISDN Access Server User Guide
to do is install and configure the supplied software on
their PC.
Ø Easy installation & configuration. The "ISDN
Access Server Printer Port" software required for printer
sharing installs quickly and requires minimal configuration.
Configuration & Management
Ø Easy Setup. Use your WEB browser from anywhere on
the LAN for configuration.
Ø Remote Management. The ISDN Access Server can be
managed, if required, from a workstation anywhere on the
LAN, using a WEB browser.
Ø Remote Monitoring. Internet access via the ISDN link,
or serial port usage, can be monitored from any workstation on the LAN.
Printer status can be checked using the standard Windows
printer features.
Security Features
Ø Configuration Data. Optional password protection is
provided to prevent unauthorized users from modifying
the configuration.
Ø Firewall Protection. All incoming data packets are
monitored and all incoming server requests are filtered,
thus protecting your network from malicious attacks from
external sources.

About your ISDN Access Server
Firewall Protection
The firewall protection provided by the ISDN Access Server
is an intrinsic side effect of IP sharing. All users on the
LAN share a single external IP address. From the external
viewpoint, there is no network, only a single device.
For internal users, the ISDN Access Server acts as a
“transparent proxy server”, translating the multiple internal
IP addresses into a single external IP address.
For external requests, any attempt to connect to local resources are blocked. The ISDN Access Server will not
“reverse translate” from a global IP address to a local IP
address.
This type of “natural” firewall provides an impregnable
barrier against malicious attacks.
Requirements
• PCs with Ethernet Network cards and 10BaseT connectors
• 10BaseT network cable(s), with RJ45 connectors. One of
these cables can be used to connect the ISDN phone line.
• Software drivers for the network cards installed on each
PC.
• ISDN phone line, fitted with a NT-1 (Network Termina-
tion 1) termination and RJ45 sockets for S/T connection.
• Internet Access account with a local ISP (Internet Service
Provider).
• For Printer Sharing, PCs must be running one of the
following operating systems:
• Windows 95 or 98

DHCP
This Chapter explains the settings on the
DHCP Server screen
Overview
A DHCP (Dynamic Host Configuration Protocol) server
provides a valid IP address, Gateway address and DNS addresses) to a DHCP client (PC or device) upon request.
The ISDN Access Server can act as a DHCP server. The
default value is ON (enabled), and use of this feature is
strongly recommended. Normally, the default values should
not need to be changed.
The PCs must be configured to act a DHCP clients. See page
24 for details of this procedure.

Routing
This Chapter explains the Routing features of
the ISDN Access Server.
Overview
While the ISDN Access Server includes a standard routing
table, this feature can be completely ignored if you do not have
a router in your LAN.
If you DO have a router, it is necessary to configure BOTH the
Router and the Routing table in the ISDN Access Server
correctly, as described in the following sections.
See page 48 for an example of configuring
both the ISDN Access Server and the
Router.
ISDN Access Server Configuration
An entry in the routing table is required for each LAN segment on your Network, other than the segment to which this
device is attached.
The routing table is accessed by the Routing link on the
navigation bar. This link appears only on the Device Screen
An example Routing screen is shown below.

Router Configuration
It is essential that all IP packets for devices not on the local
LAN be passed to the ISDN Access Server, so that they can be
forwarded to the Internet. To achieve this, the Routers must be
configured to use the ISDN Access Server as the Default
Route.
Local Router
The local router is the Router installed on the same LAN
segment as the ISDN Access Server. This router Default Route
is the ISDN Access Server itself. Typically, routers have a
special entry for the Default Route. It should be configured as
follows.
Destination IP Address

Serial Port
This Chapter explains how to configure the
serial port on the ISDN Access Server for
Internet Access.
Overview
Currently, the serial port can be used for Internet access only,
to provide additional bandwidth.
Either a modem or ISDN TA can be connected to the serial
port. The attached device will be used only when the ISDN
link is fully utilized.
To use a Serial port device
To use the serial port on the ISDN Access Server for Internet
Access:
• Connect the modem or ISDN TA to the serial port, phone
line, and power.
• Configure the ISDN Access Server's Serial Port Configu-
ration screen with details of the attached device, and the
Internet Account to which it will connect.
• If your ISP uses a non-standard log-in, or your mo-
dem/ISDN TA uses non-standard AT commands, you also
need to configure the Advanced Port screen.

Script File
If your ISP uses a standard PPP connection and authentication,
you do NOT need a script file.
Script files are used to automate the log-in process for ISPs
that use non-standard log-ins or proprietary security measures.
For example, if you connect to the Internet via CompuServe,
you DO need a script file.
Script File Commands
Three commands, listed below, can be used within a script file.
Note the following points:
• Items in [ ] are optional, and the [ ] themselves are NOT
used.
• Strings must be enclosed in double quotes.
• There must be spaces between commands and parameters
(times and strings).
Send [msec] string
Wait msec
Wait [msec] string
56
Send the characters in string, with a.
msec (milliseconds) delay between
the sending of each character.
Wait for msec milliseconds before
executing the next script line.
Wait for msec milliseconds to receive
the string. If the string is not received within the specified time, the
connection is reset.
If msec is not specified and the string
is not received immediately, an error
condition will arise.
Serial Port
Script File Variables
Eleven string variables can be used within the string above.
These are used to include special characters within the string.
Variable Description
\a alert (normally creates a beep)
\b backspace
\f form feed
\n new line
\r carriage return
\t horizontal tab
\v vertical tab
\? Literal question mark
\’ literal single quotation mark
\” literal double quotation mark
\\ literal back slash
• Quote characters are special characters.
• Because each of these variables starts with a backslash,
the backslash character ( \ ) is also a special character.
As an example, to send the string "User Name" (including the
quotes), the script file entry should be as follows:
send "\"User Name\""

Troubleshooting
This Appendix covers the most likely problems and their solutions.
Overview
This section covers some common problems that may be
encountered while using the ISDN Access Server and some
possible solutions to them. If you follow the suggested steps
and the ISDN Access Server still does not function properly,
contact your dealer for further advice.
ISDN Line
Problem 1 I’m not sure if the ISDN phone line is
working How can I test it?
Solution 1 Perform a self-test with this procedure:
1. Connect a telephone to analog port 1 or
2.
2. Pick up the phone. The LED associated
with the port should light.
3. Press the “Flash” key. The LED will
start flashing.
4. Press the following keys in sequence:
* 0 #
5. If the ISDN link is OK, you will see
both analog port LEDs flash slowly,
70
A - Troubleshooting
and hear the dial tone.
6. If you hear a busy tone, and both LEDs
flash quickly, the test has failed. Contact your phone company for advice.
Internet Access
Problem 1 Can’t connect to the ISDN Access Server
to configure it.
Solution 1 Check the following:
• The ISDN Access Server is properly
installed, LAN connections are OK,
and it is powered ON.
• Ensure that your PC and the ISDN
Access Server are on the same network
segment. (If you don't have a router,
this must be the case.)
• Ensure that your PC is using an IP
Address within the range 192.168.0.2
to 192.168.0.254 and thus compatible
with the ISDN Access Server's default
IP Address of 192.168.0.1.
In Windows, this is done by using

ISDN Access Server User Guide
1. If using static IP Addresses, ensure that
your workstations IP settings are correct, including IP address, default
gateway and DNS.
2. Ping the ISDN Access Server. Use the
“Run” command to enter the following
command:
Ping xxx.xxx.xxx.xxx
where xxx.xxx.xxx.xxx is the IP address assigned to the ISDN Access
Server’s LAN interface.
3. If the ping command fails, check that
the ISDN Access Server is connected
and ON. If it is connected and on, there
is a problem with your LAN.
4. Run your Browser and connect to the
ISDN Access Server.
5. On the ISDN screen, check that Opera-
tion is set to "Enable".
6. Check the ISDN Status screen, and
examine the Connection Log. For details of the Log messages, refer to
Connection Log on page 64.
Problem 3 My Modem/ISDN TA is working fine
with a dial-up connection. How do I find
what "Initial String" it is using before
connecting it to the ISDN Access Server
serial port?
Solution 3 Use the procedure described in Finding the
current Initial String on page 78.

Problem 4 Some applications do not run properly
when using the ISDN Access Server.
Solution 4 The ISDN Access Server processes the data
passing through it, so it is not transparent.
Some programs may have limited functionality when used with the ISDN Access
Server.
The number of supported applications is
being expanded as rapidly as possible. The
following applications and protocols are
supported by firmware V5.0:
Telnet, FTP, HTTP, ping
POP/SMTP, Archie, NNTP
TFTP, IRC, Gopher
DNS, SNMP, Real Audio

Problem 1 While adding my printer as instructed, I
received a message stating that "The
printer could not be found".
Solution 1 Some printer drivers poll the printer to see
if it is installed. If the Printer is installed as
a Local Printer, but using the ISDN Access
Server printer port, the printer does not
respond and the “Printer could not be
found” message is displayed.
73
ISDN Access Server User Guide
The following Add Printer procedure will
overcome this problem:
1. Select Network printer when asked
"How is the printer attached to your
computer?"
2. When prompted for Network Path or
Queue name enter a dummy name such
as \\12345 and select Next.
3. The printer wizard will display a
message stating "The Network Printer
is off-line". This is OK. Continue to install the printer as normal. Do NOT
attempt to print a test page.
4. When you are finished adding your
printer, go to Settings4Printers and
select your printer. The printer icon
will be faded out indicating the printer
is "off-line" and unavailable.
5. For Windows 95, select Proper-
ties4Details. For Windows NT 4.0,
select Ports. Then select print server
(PrintServer) as the port for this
printer.
6. Close the Properties window. With the
Printer icon still selected, goto the File
menu and ensure Work Off-line is NOT
checked.
7. If the printer is connected properly and
powered On, the printer icon should
now be enabled and ready for printing.

A - Troubleshooting
Problem 2 I connected and configured a WPS (Win-
dows Printing System) printer as
described, but I can’t get the print job to
print.
Solution 2 When a WPS printer is configured as a
Local printer, the printer driver polls the
printer before sending print data. Since the
printer is networked, the printer is not
detected and no data is sent.
Simply add your printer as a network
printer as described in Solution 1 above.
Some popular WPS printers are listed
below:
Canon LBP-430W
Epson ActionLaser 1300/W
Epson EPL-5500/W

Windows Peer-to-peer
Overview
This appendix explains how to configure Windows 95/98 to
enable a Peer-to-peer network, using the TCP/IP protocol.
A “Peer-to-peer” network is a network which does not have a
dedicated server, but one or more PCs will allow the other PCs
to access their resources (Disk, folders, or printer).
Procedure
The steps are:
• Install Network cards and drivers
• Install and Configure the TCP/IP protocol.
• Configure Peer-to-peer networking.
Install Network Cards & Drivers
1. Install a Network card (NIC) on each PC. Follow the
instructions provided with the NIC.
2. Connect cables from each PC to the hub.
3. Restart each PC, and install the drivers for the Network
card. Follow the instruction provided with the NIC.
4. If you need to change the drivers used by your NIC, follow
this procedure:
• Go to Settings-Control Panel-System-Device Man-
ager.
85
ISDN Access Server User Guide
• Click on the "+" sign next to "Network Adapter" to
display your NIC. Click on your NIC, then select
Properties.
• Select the Driver Tab.
• Click the "Update Driver" button, and follow the
prompts.
TCP/IP Installation
5. Navigate to the Network Properties screen. This can be
done by either:
• Selecting Start-Settings-Control Panel-Network
• Selecting the Network Neighborhood icon on the
desktop, and right-clicking to select Properties.
6. The "Configuration" tab of the Network Properties screen
will appear. An example screen is shown below.
86
C – Windows Peer-to-peer
Figure 30: Network Properties
7. If a line like the one highlighted ("TCP/IP -> NIC”) is not
listed, select Add-Protocol-Microsoft-TCP/IP-OK to add it.
8. Select Properties for the “TCP/IP -> NIC” entry. You will
see a screen like the following.
87
ISDN Access Server User Guide
Figure 31: TCP/IP Properties
9. It is essential for your PC to have an IP Address.
If you click the “Obtain and IP address automatically”
button, as shown above, you need a DHCP (Dynamic Host
Configuration Protocol) Server.
The ISDN Access Server can act as a DHCP Server. The
DHCP server will provide all necessary IP information (IP
Address, Subnet Mask, Gateway and DNS) to your PC
when it boots.
If you don’t wish to use a DHCP Server, you must give
each PC a unique IP Address, and the same Subnet Mask.
88
C – Windows Peer-to-peer
Peer-to-Peer Networking
To enable PCs to communicate with each other:
• On the Identification tab of “Network Properties” (see
Figure 30), each PC needs a unique Computer Name, but
the same Workgroup. Only PCs in the same Workgroup
will be visible to your PC.
(You can ignore the Access Control tab. In Peer-to-peer
Networks, you must use “Share Level Access Control”.)
• Each PC must log-in to the network. The Primary Net-
work Logon (see Figure 30) must be set to Client for
Microsoft Networks.
• On boot-up, when the network log-in screen appears, you
must log-in, even if you don’t use a password.
If you press ESC, or click Cancel, no network resources
will be available.
To make resources on a PC available to other users:
• On the “Network Properties” screen, (see Figure 30),
click the File and Printer Sharing button, and enable
sharing.
You will need to restart your computer for this to take effect.
• In My Computer, select the device (drive, folder, or
printer) you wish to share. Select File-Sharing or Proper-
ties-Sharing. (This option is not available if you have not
enabled File and Printer Sharing.)
Enable sharing, and give the resource a name. Provide a
password if you wish.
89
ISDN Access Server User Guide
To gain access to shared resources on other PCs:
• Select the desktop icon Network Neighborhood, and then
browse the network by selecting Entire Network. Wait a
few seconds, and you will see all PCs which:
• Are Powered On.
• In the same workgroup.
• Have enabled File and Printer Sharing.
• Double-click on a PC to view the resources it has made
available for sharing.
• To gain access to a folder or drive, select it, then select
File-Map. Select the drive letter to use for this resource,
and check the Reconnect at Startup option.
You will then be able to access this shared drive or folder
using Windows Explorer, or the File-Open/File –Save
dialogs in any Windows application.
• To gain access to a shared printer on another PC, right-
click on the printer icon, and select Install.
• If you wish, you can now go to the “Network Properties”
screen, (see Figure 30), select Client for Microsoft Net-
works-Properties and check Quick Log-in. This will speed
the boot process, and avoid error messages if the sharing
PC is not turned on.
