Chapter One: Introduction Introducing the DIVA LAN ISDN Modem 13
Bandwidth on-demand
The DIVA LAN ISDN Modem's bandwidth-on-demand feature automatically monitors data traffic and
engages the second B-channel only when needed, reducing ISDN costs.
Advanced ISDN tariff management
The DIVA LAN ISDN Modem can be configured to:
• Disable ISDN access during peak tariff rates or limit the total line usage in minutes for a given time
period.
• Set a maximum number of connections for a given period.
• Filter out specific IP protocols which consume a lot of bandwidth.
• Control broadcast traffic such as NetBEUI and TCP from reconnecting the ISDN line.
Advanced diagnostics
• On-screen display of B-channel status.
• Significant events are recorded in the Event Viewer.
• Events trigger visual or audible alarms.
• Common errors are described in non-technical language inside the Event Viewer, so that users don’t need
to analyze PPP or ISDN traces.
• Detailed ISDN information for the last two calls is retained.
• Reports list ISDN diagnostics in plain language along with help information. This is particularly useful
for solving ISDN line provisioning problems.
• Detailed traces (including ISDN (Q.931), PPP, X.25, LAPD) are available enabling technical personnel to
isolate complex communications problems.
Unsupported configurations
The DIVA LAN ISDN Modem cannot be used in the following configurations:
• Two DIVA LAN ISDN Modems cannot be interconnected (daisy-chained) via their Ethernet ports.
• The DIVA LAN ISDN Modem cannot be used on both sides when connecting to a corporate network. The
corporate network must have its own gateway.
