Appendix B: Troubleshooting Problem Potential resolutions Wireless appliance will not attach. Ensure cable loss is correctly specified in RF IN/OUT Amplitude Offset table Verify test SIM is good and installed correctly Check that cell power is sufficient (increase it up to -35 dBm to overcome interference, or if an indirect RF connection is used between the test set and phone) Try coding scheme CS-1.
Problem Potential resolutions BLER (Data Connection Type) measurements have problems Problem solutions noted above for Attach apply. Ensure the MS is capable of GMM_INFORMATION messaging. This is the type of message sent by the test set to provoke an ACK/NACK from the mobile. If the mobile is not capable of GMM information messaging, then the data connection will timeout. One possible solution: set the LLC frame check sequence to Corrupt.
Problem Potential resolutions Internet Explorer cannot access the 8960 welcome page Check that the LAN cables are good, and are properly connected. If you are using the test set’s front panel DATA port, check that the LAN jumper cable is attached on the test set's rear panel between the LAN PORT connector and the ETHERNET TO FRONT PANEL connector.
