• Precise timing in other verticals
• … lessons learnt; finally creating a time-
as-a-service (TaaS) market
• Initial focus on regulator compliance
• … by optimizing financial appliances
• Hardening and preparing for more
stringent requirements
• … by resiliently combining multiple
delivery mechanisms with assurance
Overview
Synchronization is Key Evolution of Timing in Finance
Making best use of advanced technology and emerging services
• Base stations and small cells
• Transactional services in finance and other vertical markets
• Cable networks and emerging distributed access architectures
• Utilities, e.g., substations in power networks
• Precise synchronization for IoT and distributed processes
General Need for Precise Synchronization
Accurate Timing Is Mandatory
Increasing number of appliances require ultra-precise timing
Good Enough?
Trinity of Timing Excellence in Finance
PTP Delivery
Timing Assurance
Long Holdover Atomic
Clocks
GNSS as Reference
• Sync quality monitoring
• Packet delay performance
• Monitoring slave clocks
• Benefit from PTP performance
• Traceable to UTC
• Redundancy
• Ultra-stable clock
• Surviving PTP/GNSS outages
• Various holdover options
• Leverage PTP accuracy
• Protect investment with existing NTP clients
by using …
• NTP/PTP gateway
• Enhancing NTP with precise sync signal (1PPS)
• Upgrading legacy appliances with SFP GM
