Congratulations on the purchase of your new Level One ISDN Router.
The Level One ISDN Router will allow multiple users on the LAN to gain shared Internet access. Users can share the ISDN connection and the Internet user account.

The Level One ISDN Router provides a low-cost method of giving
users of your network access to the vast resources available on the Internet. Once the Level One ISDN Router is installed and configured, the Internet is just a click away.
The Level One ISDN Router is able to use your ISDN link to connect to your ISP (Internet Service Provider), providing the required log-in information.
Alternatively, you can use the Level One ISDN Router to provide a seamless, automatic connection to another LAN, provided a matching device is installed on the other LAN.
The Level One ISDN Router incorporates many advanced features, carefully designed to provide sophisticated functions while being easy to use.
LAN Features
- 10/100 BaseT Support
The LAN connection will auto-detect 10BaseT and 100BaseT connections.
- DHCP Server Support.
A DHCP (Dynamic Host Configuration Protocol) Server provides a dynamic IP address to PCs and other LAN devices upon request.
The Level One ISDN Router can act as a DHCP Server.
- Multi Segment LAN Support.
If you have a Router,
PCs on other LAN segments can use the Level One ISDN Router to access the
Internet. A static routing table is provided to support multiple routers if
needed.
Internet Access Features
- Shared Internet Account.
All users on the LAN can share the same Internet Account.
- 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.
- PPP Authentication.
This is used to validate the log-on to your Internet Service Provider.
- Advanced Internet Functions.
- Virtual Servers. This feature allows Internet users to access Internet servers on your LAN. The required setup is quick and easy.
- User-Defined Virtual Servers. Internet users can access non-standard Internet Servers on your LAN by using this feature.
- Special Internet Applications. Internet applications such as Internet Videoconferencing, Telephony, Games Servers, and other special-purpose Servers are supported.
- Exposed Computer. One (1) PC on your local LAN can be exposed to the Internet. This allows unrestricted 2-way communication between this PC and servers or users on the Internet.
ISDN Features
- Easy Configuration
No complex technical data or
unintelligible prompts. You'll be finished in minutes!
- Intelligent B Channel Utilization
Internet access will automatically switch between 1 or 2
B channels, depending on the volume of data.
- Outgoing Call ID
The
Level One ISDN Router supports Outgoing call ID for both MSN (Multiple
Subscriber Numbering) and SAD (Sub Address).
Configuration & Management
- Easy Setup.
Connect to the Level One ISDN Router
with your WEB browser from anywhere on the LAN for configuration.
- Remote Management.
The
Level One ISDN Router can be managed from a workstation anywhere on the LAN,
using a WEB browser.
- Remote Monitoring.
Using the Web-based interface, Internet access via the ISND link can be monitored from any workstation on the LAN.
Advanced Functions
- Dial-in Remote Access.
Remote users can dial in using their ISDN phone line, and use the Level One ISDN Router to connect to the LAN and access LAN resources.
- LAN-to-LAN Connectivity.
Using 2 Level One ISDN Routers, 2 LANs can be connected via the ISDN link. The Level One ISDN Router will dial the remote LAN whenever required. Operation is completely automatic and
transparent.
Security Features
- Configuration Data.
Optional password protection is provided to prevent unauthorized users from modifying the configuration.
- 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.
Firewall Protection
The firewall protection provided by the Level One ISDN Router 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 Level One ISDN Router 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 Level One ISDN Router 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.
