The cellular WAN HWIC will provide the following software functionality:
• Dialup connection (DDR)—Dialup allows users to build up connections from a local network to
remote locations, e.g., to an Internet Provider (ISP) and to exchange data.
• Fallback connection (DDR backup)—the cellular HWIC allows the user to configure the cellular
modem to initiate a dialup connection when connection to a primary service is lost.
• Teardown after Fallback (Part of Fallback DDR)—Once a primary connection has failed and the
cellular connection is in "fallback" mode, the cellular HWIC tears down the connection once the
primary connection is available.
• Automatic teardown—After a configurable timeout value, the cellular HWIC automatically tears
down a connection if there has been no activity.
• Portable Application—You can move the router into different coverage areas (different Base stations
within the same service provider) and the router establishes a connection with the nearest cell
infrastructure automatically. This is different from the mobile capability that cell phones offer.
• Remote Access—The cellular HWIC allows users to connect with the cellular HWIC router through
the cellular network.
• Bidirectional Keepalive—The cellular HWIC allows you to configure keep alive to check the WAN
connection at an interval that you can configure. In the event of a failure of the keep-alive request,
the cellular HWIC will clear the existing connection and reestablish a new connection. This feature
works in both directions—from the cellular network to the router, and from the router to the cellular
network
• Auto-detect—The cellular HWIC automatically detects and utilizes the best available connection
from a selected service provider.
• Mobile IP Support—The cellular HWIC allows you to maintain a seamless connection while
transitioning between areas covered by different foreign agents.
