Selecting option 1 from the main menu produces this screen:
Many of the Command Menu options have corresponding configurable
parameters in other menus of the UI console. Issuing commands will not
affect the configured parameters except at the time of initial execution.
Menu Option 1 Resetting the highest priority timing source
This action causes re-arbitration of the clock to the highest priority source
available.
Menu Option 2 Resetting the PRI NAC
Issuing this command reboots the NAC.
Any configuration changes that are not saved to NVRAM will be lost
when the NAC reboots.
Menu Option 3 Enter/Exit span-to-span pass-thru loopback mode
This option allows for a span-to-span loopback, where all of the DS0s on
span 1 are connected to all of the DS0s on span 2 through the time slot
interchanger (TSI). This command will drop calls.
This option is useful for testing purposes.
There will not be a prompt to authorize dropping calls if initiated from
the command line interface (CLI).
