When working with maritime satellite communication systems like the FELCOM series (FELCOM-15, FELCOM-16, FELCOM-18, and FELCOM-19), users may encounter call rejection errors that require systematic troubleshooting. Understanding the recent changes in satellite communication protocols and diagnostic steps can help resolve these communication challenges efficiently.
Initial Diagnostic Steps
If you receive a "Call rejected by LES because of request barred" error message, follow these critical verification procedures:
- Verify CN (Carrier-to-Noise) level is within acceptable range
- Confirm BBER (Bulletin Board Rate) level is displaying zero
Important Update: As of September 20, 2024, INMARSAT has restructured its partner model, replacing Point of Service Activations (PSA) and Accounting Authorities (AA).
Advanced Troubleshooting
To comprehensively diagnose potential communication issues:
- Press F8, then select 8, 2 to display your Land Earth Station (LES) list
- Take a screenshot of the terminal's LES details
- Contact your designated accounting authority with the screenshot
- Example shown below
Error Message Interpretation
Different error messages indicate distinct underlying issues:
| Error Message | Potential Cause |
|---|---|
| "Call rejected by LES" | Potential configuration or authorization problem |
| "No response from LES" | Potential hardware or connection issue |
Pro Tip: Verify you're using the correct Land Earth station as per your new accounting authority guidelines.
