No, there is no standard[1]. A system like this is always tailored to
the consumer of the PPS pulses and its requirements. Ie you need to
figure out what you want to do with those PPS, then figure out what
the desired behaviour during hold-over and recovery is and from that
you can design the frequency standard.
