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.

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-preferred side. 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.
