This troubleshooting guide was created as an interim reference document for use in the field.
Troubleshooting: Installation 68P09255A69-3 Troubleshooting: Installation Cannot Log into Cell-Site Table 6-1: Login Failure Troubleshooting Procedures Step Action 1 If the MGLI LED is solid RED, it implies a hardware failure. Reset MGLI by re-seating it. If this persists, install GLI card in MGLI slot and retry. A Red LED may also indicate no termination on an external LAN connector (power entry compartment at rear of frame). 2 Verify that the span line is disconnected at the Span I/O card.

Basic Troubleshooting: RF Path Fault Isolation 68P09255A69-3 Basic Troubleshooting: RF Path Fault Isolation Overview The optimization (RF path characterization or calibration) and post-calibration (audit) procedures measure and limit-check the BTS reported transmit and receive levels of the path from each BBX to the back of the frame. When a fault is detected, it is specific to a receive or transmit path. The troubleshooting process in this section determines the most probable cause of the fault.
Basic Troubleshooting: RF Path Fault Isolation 68P09255A69-3 Single-Sided BLO Checkbox When performing a calibration with the TX Calibration... or All Cal/Audit... functions, the Single-Sided BLO checkbox should not be checked when the redundant BBX is being calibrated. When a calibration fails with the redundant BBX selected, try re-running the calibration with the Single-Sided BLO checkbox unchecked.

Troubleshooting: CSM Check-list 68P09255A69-3 Troubleshooting: CSM Check-list Problem Description Many Clock Synchronization Manager (CSM) board problems may be resolved in the field before sending the boards to the factory for repair. This section describes known CSM problems identified in field returns, some of which are field-repairable. Check these problems before returning suspect CSM boards. Intermittent 19.
Troubleshooting: CSM Check-list 68P09255A69-3 GPS Bad RX Message Type This is believed to be caused by a later version of CSM software (3.5 or higher) being downloaded, via LMF, followed by an earlier version of CSM software (3.4 or lower), being downloaded from the CBSC. Download again with CSM software code 3.5 or higher. Return CSM board back to repair center if attempt to reload fails.
Troubleshooting: SCCP Backplane 68P09255A69-3 Troubleshooting: SCCP Backplane Introduction The SCCP backplane is a multi-layer printed circuit board that interconnects all the SCCP 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.
Troubleshooting: SCCP Backplane 68P09255A69-3 CIO Connectors RF RX antenna path signal inputs are routed through RX paths of the DRDCs or TRDCs at the RF interface panel (rear of frame), and through coaxial cables to the two MPC modules. The three “A” (main) signals go to one MPC; the three “B” (diversity) to the other. The MPC outputs the low-noise-amplified signals through the SCCP backplane to the CIO where the signals are split and sent to the appropriate BBX.
Troubleshooting: SCCP Backplane 68P09255A69-3 Digital Control Problems No GLI Control via LMF (all GLIs) Table 6-19: No GLI Control Through LMF (All GLIs) Step Action 1 Check the Ethernet LAN for proper connection, damage, shorts, or opens. 2 Be sure the LAN IN and OUT connectors in the power entry compartment are properly terminated. 3 Be sure the proper IP address is entered in the Network Login tab of the LMF login screen. 4 Logout and Exit the LMF, restart the LMF, and re-login to the BTS.
Troubleshooting: SCCP Backplane 68P09255A69-3 No BBX Control in the Shelf Table 6-23: MGLI Control Good - No Control over Co-located BBXs Step Action 1 Visually check all GLI connectors (both module and backplane) for damage. 2 Replace the remaining GLI with a known good GLI. 3 Visually check BBX connectors (both module and backplane) for damage. 4 Replace the BBX with a known good BBX.
Troubleshooting: SCCP Backplane 68P09255A69-3 DC Power Problems WARNING Potentially lethal voltage and current levels are routed to the BTS equipment. This test must be carried out with a second person present, acting in a safety role. Remove all rings, jewelry, and wrist watches prior to beginning this test. No DC Input Voltage to SCCP Shelf Power Supply Modules Table 6-26: No DC Input Voltage to Power Supply Module Step 1 Action Verify DC power is applied to the frame.

Troubleshooting: RFDS 68P09255A69-3 Troubleshooting: RFDS Introduction The RFDS is used to perform Pre-Calibration Verification and Post-Calibration Audits which limit-check the RFDS-generate and reported receive levels of every path from the RFDS through the directional coupler coupled paths. In the event of test failure, refer to the following tables.
Troubleshooting: RFDS 68P09255A69-3 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. Replace the RFDS with a known-good unit and retest. All Tests Fail on a Single Antenna If all path failures are on one antenna port, forward and/or reflected, make the following checks.

BBX Gain Set Point vs. BTS Output 68P09255A69-3 BBX Gain Set Point vs. BTS Output Usage & Background Table C-1 outlines the relationship between the total of all code domain channel element gain settings (digital root sum of the squares) and the BBX Gain Set Point between 33.0 dBm and 44.0 dBm. The resultant RF output (as measured in dBm at the BTS antenna connector) is shown in the table. The table assumes that the BBX Bay Level Offset (BLO) values have been calculated.

CDMA Operating Frequency Programming Information 68P09255A69-3 CDMA Operating Frequency Programming Information Introduction Programming of each of the BTS BBX synthesizers is performed by the BTS GLI2s via the Concentration Highway Interface (CHI) bus. This programming data determines the transmit and receive transceiver operating frequencies (channels) for each BBX. 1900 MHz PCS Channels Figure D-1 shows the valid channels for the North American PCS 1900 MHz frequency spectrum.
