Enhancing Air Traffic Communication Reliability at Tribhuvan International Airport

Mahavir Shree International successfully completed the Supply, Delivery, Installation, and Testing of Spare Parts for the Optical Link between RCR and ACC/APP/TWR for VCCS ATS communication at Tribhuvan International Airport (TIA), Kathmandu. This project ensured seamless and secure E1 signal transmission critical for air traffic management by integrating advanced RAD Multiservice Access Nodes (MP4104) and Megaplex-4 systems into the airport’s communication network.

Key Deliverables

✓ Supply and installation of RAD communication equipment:

✓ RAD MP-4100M-VS/16E1T1/EOP

✓ RAD MP-4104-2/48R/622GREAUTPR/155SK

✓ RAD SFP-3H modules

✓ RAD CBL-G703-8/RJ45/ST adapter cables

✓ Configuration of redundant Multiservice Access Node (MSAN) systems for uninterrupted VCCS operation.

✓ Installation of a 150-meter 8-core optical fiber link between RCR and ATS units.

✓ Comprehensive testing and commissioning of the VCCS communication system.

Impact

The upgraded optical communication link has strengthened TIA’s Voice Communication and Control System (VCCS), enabling uninterrupted and secure communication between the Tower (TWR), Approach Control (APP), and Area Control Centers (ACC). The integration of RAD’s MP4104 systems ensures automatic redundancy activation, preventing downtime and maintaining 24/7 operational readiness. This project has significantly enhanced communication reliability, safety, and coordination in air traffic management.

Conclusion

The successful deployment of RAD’s Megaplex-4 system and supporting equipment by Mahavir Shree International represents a key step in TIA’s modernization of air traffic communications. The project’s completion ensures continuous, interference-free VCCS operations, reinforcing the airport’s commitment to safety, operational excellence, and technological advancement in aviation communication infrastructure.
