is the master for b 4 and b 3 is the master for b 5 then the paired synchronization b 2 and b 3 are first synchronized with b 1 then b 4 is synchronized with b 2 and b 5 with b 3 will result in system wide synchronization within two cycles in the same system synchronization may also be performed without the master principle then however the slz would have to ensure that once buses have been synchronized they will remain synchronized i e a jump i e a correction on one bus must also take place on all the other buses synchronized with it in addition it may be advantageous but not necessary if the time master of a bus to be synchronized also has direct access to the corresponding partner bus in this case the slz may be set up only on the potential time masters of a bus in other words the message of the slz regarding the size of the jump to be set i e the correction to be set is eliminated and or greatly simplified as an alternative to the mechanism described in section bz in this case a phase adjustment may be achieved through more gradual changing of the.
