Troubleshooting 68P09255A57-2 Table 6-4: Troubleshooting Code Download Failure Step Action 3 Communication to MGLI3 must first be established before trying to talk to any other BTS device. MGLI3 must be INS_ACT state (green). 4 Verify the card is physically present in the cage and powered-up. 5 If card LED is solid RED, it implies hardware failure. Reset card by re-seating it. If this persists, replace card from another slot & retry.

Troubleshooting 68P09255A57-2 Checksum Failure The CSM could have corrupted data in its firmware resulting in a non-executable code. The problem is usually caused by either electrical disturbance, or interruption of data during a download. Attempt another download with no interruptions in the data transfer. Return CSM board back to repair center if the attempt to reload fails. GPS Bad RX Message Type This is believed to be caused by a later version of CSM software (3.

Troubleshooting 68P09255A57-2 C-CCP Backplane The C-CCP backplane is a multi-layer board that interconnects all the C-CCP modules. The complexity of this board lends itself to possible improper diagnoses when problems occur. Connector Functionality The following connector overview describes the major types of backplane connectors along with the functionality of each. This will allow the Cellular Field Engineer (CFE) to: Determine which connector(s) is associated with a specific problem type.
PAGE 11
Troubleshooting 68P09255A57-2 GLI3 Ethernet “A” and “B” Connections These BNC connectors are located on the C-CCP backplane and routed to the GLI3 board. This interface provides all the control and data communications between the master GLI3 and the other GLI3, between gateways, and for the LMF on the LAN. BBX2 Connector Each BBX connector consists of a Harting 2SU/1SU digital connector and two 6-conductor coaxial connectors.
PAGE 12
Troubleshooting 68P09255A57-2 No GLI3 Control through Span Line Connection (All GLI3s) Follow the procedure in Table 6-17 for problems with GLI3 control. Table 6-17: No GLI3 Control through Span Line Connection (Both GLI3s) Step Action 1 Verify C-CCP backplane Shelf ID DIP switch is set correctly. 2 Verify that the BTS and GLI3s are correctly configured in the OMCR/CBSC data base. 3 Visually check the master GLI3 connector (both board and backplane) for damage.

Troubleshooting 68P09255A57-2 All RX and TX paths fail If every receive or transmit path fails, the problem most likely lies with the rf converter board or the transceiver board. Refer to Table 6-27 for fault isolation procedures. Table 6-27: RFDS Fault Isolation - All RX and TX paths fail Step Action 1 Visually check the master RF converter board (both board and backplane) for damage. 2 Replace the RF converter board with a known good RF converter board.

Channel Frequencies 68P09255A57-2 Channel Frequencies Introduction Programming of each of the BTS BBX synthesizers is performed by the BTS GLIs via the CHI bus. This programming data determines the transmit and receive transceiver operating frequencies (channels) for each BBX2. 1900 MHz PCS Channels Figure D-1 shows the valid channels for the North American PCS 1900 MHz frequency spectrum.

Channel Frequencies 68P09255A57-2 Calculating 1900 MHz Center Frequencies Table D-1 shows selected 1900 MHz CDMA candidate operating channels, listed in both decimal and hexadecimal, and the corresponding transmit, and receive frequencies. Center frequencies (in MHz) for channels not shown in the table may be calculated as follows: TX = 1930 + 0.05 * Channel# Example: Channel 262 TX = 1930 + 0.05*262 = 1943.10 MHz RX = TX - 80 Example: Channel 262 RX = 1943.10 - 50 = 1863.

PN Offset 68P09255A57-2 PN Offset Background All channel elements transmitted from a BTS in a particular 1.25 MHz CDMA channel are orthonogonally spread by 1 of 64 possible Walsh code functions; additionally, they are also spread by a quadrature pair of PN sequences unique to each sector. Overall, the mobile uses this to differentiate multiple signals transmitted from the same BTS (and surrounding BTS) sectors, and to synchronize to the next strongest sector.

Test Equipment Setup 68P09255A57-2 Test Equipment Setup Purpose This appendix provides information on setting up the HP8921 with PCS interface, the HP8935 and the Advantest R3465. The Cybertest test set doesn’t require any setup. HP8921A Test Equipment Connections Table F-1 depicts the rear panels of the HP 8921A test equipment as configured to perform automatic tests. All test equipment is controlled by the LMF via an IEEE-488/GPIB bus.
