3rd Generation BITS

Future-Proof & Resilient Protection Against GPS Threats

Future Proof

3rd Generation BITS

Today’s timing systems are required to provide services to both legacy TDM (frequency) and Next-Gen (packet) systems. Our 3rd Generation BITS provides a sustainable, future-proof solution that will meet all your network’s timing needs. With GPS vulnerabilities and 5G deployments on the rise, 3rd Generation BITS will modernize and harden your synchronization network.

BITS Technology – Generations One & Two

1st Generation BITS met the needs for the telecom industry’s rising importance in a world where communication needed to be faster and more reliable.

Many of these early systems are still in use today. These workhorses were solidly built but lacking the scalability features required for modern telecom networks.

2nd Generation BITS was an improvement that added remote connectivity and management plus software upgrade functionality along with these products:

  • TimeProvider 1100 – seen below
  • SSU 2000
  • TimeHub 5500
