MMI-SYNC
Issue 4 May 2002
10-1133555-233-123
If the MMI circuit pack that provides synchronization is craft busied out, it will not
affect the PN synchronization. The signal is still provided by the busied-out pack.
There is no affect on synchronization if the technician issues a release of the
busied-out MMI. Synchronization is not affected by a warm start of the system
(reset system 1). For all other restarts (reboot through cold 2), MMI
synchronization recovers during board insertion.
