Airlink II user manual Registration Problems

User’s Manual

Registering - After acquiring a link, the modem will perform an encryption key exchange, and register its IP Address. If the registration is successful, the Reg LED will be turned on. Again, the TxRx LED will flash briefly during this time.

CDPD Raven II

If the Reg light flashes then this is indicating your side preference is set for either “A-side preferred” or “B-side preferred” and that the modem has switched to the non-preferredside. The modem will de-register after ten minutes or so and go back to the preferred side. If there is still no service on the preferred side, it will switch back to the non-preferred side and continue this pattern forever.

Setting your modem to a “preferred” side preference (or the wrong side preference) can incur additional charges on your CDPD bill when the modem uses the side that your provider does not use.

2.4.1 Registration Problems

If the registration was unsuccessful, the Chan, Link, and RSSI LEDs will blink off while the modem scans to another channel. When the modem finds another CDPD channel, the preceding sequence will repeat. If the modem is never able to register successfully:

•The modem can be configured with the wrong side preference. Recheck the Side Preference setting in the modem.

•The authentication parameters might need to be reset.

Please contact AirLink Tech Support and we will contact your CDPD Service Provider to have them verify that your IP address is valid and to reset your authentication parameters. Be prepared to provide us your modem's EID, too.
