3rd Generation BITS
Modernizing Legacy Equipment
From 2nd to 3rd Generation BITS
BITS stands for Building Integrated Timing Supply. It’s a synchronous Time Division Multiplexing (TDM) signal that synchronizes data networks and communication systems. BITS clocks are often used in networks that need precise timing, such as those used in financial trading and telecommunications.
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.
Above are four Syncworks’ output panels with 20 outputs each and two TimeProvider® 4100s.
The TP 4100 is an investment in a platform that will evolve with industry needs. It features an IEEE 1588 v2 PTP grandmaster with PTP, NTP and SyncE capabilities. It meets Primary Reference Time Clock Class A, Class B and enhanced Primary Reference Time Clock (ePRTC) specifications and Class C and D specifications for multidomain boundary clock.

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
