Page 47: Troubleshooting
Troubleshooting Troubleshooting When troubleshooting a SBU ONT unit, consider the following two principles: • Because voice and data signals originate at the OLT equipment, a failure of all services normally indicates the problem is before the SBU ONT. A failure at the OLT equipment normally results in a loss of service to multiple customers. • The OLT has diagnostic testing procedures that can monitor the status of every SBU ONT in the system, which very often can direct you to the root cause of the trouble. NOTE The home telephone wires are connected using pivot connectors, and the RJ‐ 11 jack serves as a test access point. In this configuration, inserting a telephone cable into the RJ‐11 jack will disconnect the SBU ONT from home wiring and connect the SBU ONT to the inserted cable instead. This allows the home owner or service provider to diagnose SBU ONT or home wiring related problems. Inserting an RJ‐11 jack (such as a telephone cable or telephone test set) into the connector, will connect the telephone set and also disconnect the subscriber service from the SBU ONT. Hence fault may be isolated to the SBU ONT or premises wiring. This section describes how to troubleshoot and correct the following: • “Faults Indicated with LEDs” • “SBU ONT Trouble Isolation” on page 36 • “Signal Level Verification” on page 39 • “UPS Communication Signals” on page 41 Faults Indicated with LEDs Begin troubleshooting at the SBU ONT by checking to see if all LEDs are in their normal state, shown in Table 9 on page 33. There are separate LEDs for each Ethernet RJ‐45 jack that appear on the SBU circuit board. If the LEDs are in their normal state, refer to “LEDs in Normal State” ... -

Total Access 372 Small Business Unit ONT Installation and Maintenance Guide LEDs in Fault State Descriptions of each LED are listed in Table 9 on page 33 with possible causes for fault LED conditions. A flow chart for troubleshooting the problem for each fault condition is provided in Figure 18 on page 37. SBU ONT Trouble Isolation This section describes how to isolate problems based on faults reported through LEDs: • “UPS Power LEDs” • “NET Status LED Off” on page 37 • “POTS Troubleshooting” on page 38 UPS Power LEDs Power A UPS LED that is off indicates there is no power. Refer to Table 10 to determine if a problem exists. -
Page 49: Net Status Led Off
Troubleshooting NET Status LED Off The LED Off indicates no signal detected, or the SBU ONT has been administratively shut down. This can be caused by one of the following conditions: • Failure at the OLT • Failure between the OLT and the SBU ONT before the drop wire optical connector • Drop wire optical connector • Malfunction of LED at SBU ONT Utilize the flowchart in Figure 18 to determine the cause and correct the problem.

Page 50: Pots Troubleshooting
Total Access 372 Small Business Unit ONT Installation and Maintenance Guide POTS Troubleshooting When the POTS LED is red, the port is in a fault condition. To correct the problem, do the following: • Contact the OLT administrator and ensure the port is provisioned and working. If the port is provisioned and working, proceed to the next step. • Disconnect the CPE wiring and wait 30 seconds. If the Red LED turns off, the trouble is a short in the housing wiring. If the RED LED remains on, the unit is probably bad. Cleaning and Inspection of Components Because the physical size of the transmission core of the optical fiber is typically only 9 microns in size, debris such as a single particle of dust or smoke or strand of hair can impair the path enough to cause transmission problems. This section provides information and procedures for the following: • “Cleaning Suggestions” • “Cleaning the Connectors” • “Signal Level Verification” on page 39 Cleaning Suggestions Following is a list of suggestions for cleaning connectors, ferrules, and bulkheads: •... -
Page 51: Signal Level Verification
Troubleshooting Signal Level Verification The following sections detail signal level verification if problems are encountered when service activation of an installed SBU ONT is performed. Both Downstream signal Level Verification on page 40 and “Upstream Signal Level Verification” on page 40 are discussed. Downstream Signal Level Verification A valid optical power level delivered by the OLT must be received at the drop cable point to assure proper SBU ONT ranging and operation. There is one optical wavelength (1490 nm) to consider in the downstream direction that will contribute to the absolute optical power level delivered to the SBU ONT. The 1490 nm wavelength is used for digital data. The individual optical power level that should be present at the optical fiber that is connected to the SBU ONT are listed in Table 11. Table 11. Downstream Power Level Optical Wavelength Minimum Power Level 1490 nm (digital) –28 dBm To verify the correct downstream optical signal levels are present: Ensure all connectors are clean and dry. Refer to “Cleaning and Inspection of Compo‐ nents” on page 38 for details. 2. Setup and calibrate the OPM or OLTS for wavelengths that apply to FTT transmissions (that is 1310 nm and 1490). Verify the test equipment is capable and setup for wavelength filtering so that you do not obtain an undesired reading of the absolute optical power from all contributing wavelengths. Instead you are trying to measure the individual wavelength optical power levels. -

Total Access 372 Small Business Unit ONT Installation and Maintenance Guide • If the measurement results are within range, perform the steps in “Upstream Signal Level Verification” on page 40. Upstream Signal Level Verification A valid optical power level delivered by the SBU ONT must be received by the OLT in burst mode at 1310 nm that is controlled in the upstream direction by grants given by the OLT. The individual optical power level that should be present at the optical bulkhead that is located on the SBU ONT is listed in Table 12. Table 12. Upstream Power Levels Optical Wavelength Minimum Power Level Maximum Power Level 1310 nm 0 dBm +5 dBm To verify the correct upstream optical signal level is present: Ensure all connectors are clean and dry.

Page 53: Ups Communication Signals
Troubleshooting UPS Communication Signals The communication signals of the UPS are isolated from the internal circuitry via open SIG RTN collector opto‐coupled transistors. The connection (Signal Return) is a common return point for all communication signals. In the typical application, the attached equipment digital ground connects to Signal Return, and pull‐up resistors turn the open collector signals into logic levels. A pinout of the communication signals is shown in Table 13. Table 13. UPS Communication Signal Descriptions Signal Description +12 VDC Vo+ (+ Voltage output) 12 V RTN Return path for +12 VDC SIGNAL RETURN Signal return ON BATTERY Low when operating from utility line Open when operating from battery REPLACE BATTERY Low when battery is charged Open when battery fails self‐test BATTERY MISSING Low when battery is present Open when battery is missing LOW BATTERY Low when battery is near full charge capacity Open when operating from a battery with less than 20% capacity 61287722G1-5B... -
