Description (partial)

The interface flap on a OC48 SPA might cause the MSC to reload.

When the SONET clock is configured "source line" on both ends, the framer might
cause the interface to flap continously.  This might cause be too many
read/write sent to the PCI bus which in turn causes a critical error triggering
the MSC reload.

If the OC48 SPA interface is connected back to back with another CRS-1 OC48
interface (fixed PLIM or SPA) this other side could also hit the problem and
have the MSC reloaded.
