Select the Config menu, choose Clock, and then perform the following tasks:
1 Using the spacebar to cycle through the configuration options, set the
Primary Reference. This selection determines the primary source for
clock synchronization. See
Table 4 .
2 Set the Secondary Reference for synchronization. See Table 4 .
3 Set the Timing Reference Switching (revertive or non revertive).
Setting the timing reference to revertive causes the clock to revert to the
primary clock when it is valid.
4 To manually force the clock synchronization mode, set Force to the
desired mode. The default setting is normal. See
Table 4 for other
configuration options.
A service or transport must be configured as in service (IS)
prior to being selected as the synchronization source.
