Reference/Comments The synchronization plan should include interfaces, customers (both retail and wholesale) and network peers. The plan should encompass all services provided by and used by the Network Operators and Service Providers. The plan should include: synchronization hierarchy, failure avoidance, redundancy and backup for resilience, FMECA and SPOFA. Synchronization performance expectations (24hr slip rate) should be determined in both primary and backup operation scenarios. Timing loop analysis must be performed in the primary arrangement and in all potential failure scenarios. Note: This Best practice could impact 9-1-1 operations.
