3  Definitions, symbols and abbreviationsWord‑p. 7

3.1  Definitions

Network Synchronisation:
generic concept that depicts the way of distributing a common frequency to all elements in a network
Reference Timing Signal:
timing signal of specified performance that can be used as a timing source for a slave clock
Holdover mode:
operating condition of a clock which has lost its controlling reference input and is using stored data, acquired while in locked operation (that is while controlled by an external input reference), to control its output. The stored data are used to control phase and frequency variations, allowing the locked condition to be reproduced within specifications.
