Chapter 4 Provisioning the TimeProvider

Use the ED-EQPT command to provision each IOC. This command allows you to 
select which IOC is Active and which is Standby; to switch the Active and Standby 
IOCs; to place a IOC “In Service” or “Out of Service”; and to define the oscillator type 
to Type I or ST3E for a quartz-based IOC or to Type II or ST2 for a Rubidium IOC.

ED-EQPT:[<tid>]:<aid>:[<ctag>]::<keyword>=<value>;

This command has a default access level of ADMIN.

ED-EQPT::IOC1:TS1000::IOCSTATE=INSERV;

This command places IOC 1 in the “In Service” mode. Use this command when you 
have taken an IOC out of service and are now ready to put it back in service.
