About your ISDN Access
Server
This Chapter provides an overview of the
ISDN Access Server's features and capabili-
ties.
ongratulations on the purchase of your new ISDN
Access Server. The ISDN Access Server allows multiple
SOHO (Small Office Home Office) users to share a
single Internet user account over an ISDN phone link. It
provides a low-cost method of giving users of your network
easy access to the vast resources available on the 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 con-
nect an analog (POTS) telephone, answering machine, or fax.

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
ØBuilt-in Hub. The built-in 4-port hub saves the cost and
additional wiring of a separate hub.
ØHassle-free LAN Installation. Just plug it in, whether
or not you wish to use the built-in hub.
ØDHCP 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.
ØMulti 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
ØShared Internet Account. All users on the LAN can
share the same Internet Account.
ØAdditional Bandwidth via Serial Port. If, in the
future, the ISDN link provides insufficient bandwidth, you

About your ISDN Access Server
can connect a modem or ISDN TA to the serial port to
provide increased bandwidth.
ØDial-On-Demand & Auto-Disconnect. A connection
is established to the Internet as required, and automati-
cally disconnected when no longer needed. This reduces
on-line charges to the minimum possible level.
ØPPP Authentication. This is used to validate the log-on
to your Internet Service Provider.
ISDN Features
ØEasy Configuration. No complex technical data or
unintelligible prompts. You’ll be finished in minutes!
ØIntelligent B Channel Utilization. Internet access will
automatically switch between 1 or 2 B channels, depend-
ing on the volume of data.
ØOutgoing call ID. The ISDN Access Server supports
Outgoing call ID for both MSN (Multiple Subscriber
Numbering) and SAD (Sub Address).
ØAnalog Ports. Two (2) analog ports are provided, to
allow connection of your existing analog telephone, an-
swering machine, or fax.
ØAnalog 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
ØLAN 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.
ØEasy installation & configuration. The "ISDN
Access Server Printer Port" software required for printer
sharing installs quickly and requires minimal configura-
tion.
Configuration & Management
ØEasy Setup. Use your WEB browser from anywhere on
the LAN for configuration.
ØRemote Management. The ISDN Access Server can be
managed, if required, from a workstation anywhere on the
LAN, using a WEB browser.
ØRemote Monitoring. Internet access via the ISDN link,
or serial port usage, can be monitored from any worksta-
tion on the LAN.
Printer status can be checked using the standard Windows
printer features.
Security Features
ØConfiguration Data. Optional password protection is
provided to prevent unauthorized users from modifying
the configuration.
ØFirewall 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 re-
sources 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.

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

LED Indicators
APower Lights when power is ON.
BLAN ERR –Indicates an error, but normally
lights up briefly during power On. See the
following table for more information.
LNK –Traffic is being transmitted or
received on the LAN.
This LED also works in conjunction with
the ERR LED to indicate errors. See the
following table for more information.
COL –Packet collision. Collisions are
normal; only if this light is on most of the
time is there a problem.
CWAN SD –Flashes when data is sent through the
serial (WAN) port.
RD –Flashes when data is received through
the serial (WAN) port.
CD –Carrier Detect. This is ON when the
WAN (serial port) connection is active.
DISDN LK –ON while the ISDN connection is
being used.
B1 –Flash while the 1
st
B channel is in use.
B2 –Flash while the 2
nd
B channel is in use.
ETEL T1 –ON while analog port 1 is in use.
T2 –ON while analog port 2 is in use.
All 12 LEDs will light briefly on power on.
This is normal.

Chapter 2
Setup:
Internet Access
This Chapter explains how to install and
configure the ISDN Access Server for Inter-
net Access.
Overview
Setup involves:
•Hardware Installation
•ISDN Access Server configuration
•PC configuration
Software installation is required only for printer sharing. Refer
to Chapter 10 –Printer Sharing for details.
Hardware Installation
1. Connect Network Cables
For each PC, connect one end of a 10BaseT network cable
to the ISDN Access Server’s RJ-45 socket (port1 to 4) and
the other end into the RJ45 socket on the PC. Cable length
should not exceed 100 meters (yards).
If you don't wish to use the ISDN Access
Server's built in hub, use any of ports 1 to 4
to connect the ISDN Access Server to your
existing hub.
2

Setup: Internet Access
If using the ISDN Access Server's built-in
hub with another hub, use the "Uplink"
10Base-T connector to connect to the other
hub's MDI-X port. Note that when the Uplink
port is in use, port 4 can NOT be used.
3. Connect ISDN Phone Line
Using a cable fitted with RJ45 plugs, connect the ISDN port
on the ISDN Access Server to the S/T interface on the NT-1
(Network Termination 1) ISDN terminator.
4. Connect Printer (IAS-2410 only)
Using a standard printer cable, connect the printer to the
printer port on the ISDN Access Server.
5. Power On and Check the LEDs
Connect the supplied power adapter to the ISDN Access
Server and press the ON/OFF switch on the back of the ISDN
Access Server. (In is ON.) When the ISDN Access Server is
powered On, all LEDs should blink, then, except for the PWR
LED, go off.
•The LAN (LNK) LED will blink during normal operation
•The ISDN and TEL LEDs will light when the relevant
port is in use.
•If the ERR LED stays on, or both the ERR and LNK
LEDs blink, there is a hardware problem. For more in-
formation on the LEDs, refer to Link/Error LEDs on page
10.
Warning! Only use the power adapter provided. Using
a different one may cause hardware damage.
