4.5. Checking the Status of the Connection
The OnAir LED reflects the status of the connection (see the
table in section 4.1).
The Watcher screen also displays a Status message. See Table

Awaiting
confirmation This step is the equivalent of "logging-on" to a
network. The CDPD network checks the
AirPath 300's credentials to ensure the device is
authorized for network service.
Establishing data link This is the first step in establishing a connection
on the CDPD network. It involves
“handshaking”, where both ends of the data link
agree on the protocols to be used.
Initializing
encryption This is the second step in establishing a
connection on the CDPD network. All network
traffic is encrypted for security reasons. This step
involves the transmission of an encryption key
that is used by both ends of the data link to
encrypt and decipher the data.
Registered The registration was successful. Your device is
ready to receive and send email, browse the
Internet, and use other applications wirelessly.
Inter-area transfer CDPD service areas are divided into geographic
zones called "cells". Each cell has its own
cellular base station. This message occurs when
travelling from one cell to another and it indicates
that you are being "handed off" to a different cell.
