Protocol Logging and Data Channel Troubleshooting
Last updated: December 3, 2008
Protocol Logging
-
Error message appears when you start Protocol Logging on the test set: The test set must be connected via a LAN or WAN to a PC running the Wireless Protocol Advisor (WPA). Check connections, installation of software, IP addresses and gateway addresses.
-
WPA is no longer connected to the test set: Anytime you preset the test set, the connection to the WPA is lost. Reestablish the connection from the configuration view of the WPA.
Data Channel
-
If your data channel application does not seem to be working, try pinging the device. The test set has a ping feature, and so do most computer operating systems. See
Ping
for more information.
-
Ping log has an unknown IP address: If you log a Ping that originated from the test set, the Ping Downlink Source Address and the Uplink Destination Address have a fixed address of 130.29.181.203. This is because the test set uses an internal address to originate IP data from the test set to the mobile station. See
Protocol Logging During Ping
for more information.
-
Ping does not work: Verify that your device supports ping. The device must have a PDP context established for GPRS or EGPRS or a PPP connection for GSM CSD in order for ping to work. This may require that you initiate a data transfer from the mobile station. Also, Ping and Data Channel are only available in when the connection type is set to
Auto
.
-
Can't find where to set the mobile station IP address: Switch the
Connection Type
to
Auto
first.
-
BER and FBER measurements are invalid when using the data channel: The BER and FBER measurements are not supported during data connections.
-
What is the APN (Access Point Name) that I need to include with the dial string when using dial-up? No APN is needed.
-
When using your mobile station as a modem, make sure the mobile station recognizes that the data cable is attached. You may need to allow the mobile station to camp or attach to the test set and then connect the data cable. The mobile station may also display a message indicating the cable has been connected.
