Figure 3-41. Synchronization Timing Loop
A correctly designed network has no loops and each piece of equipment in the
network is supplied by a clock of equal or lower stratum (that is, the inputs to a
Stratum 3 clock should NEVER be from a Stratum 4 device).
It is strongly
recommended that the network administrator be consulted before
administering any synchronization changes.
