The Diag_PosJust bit forces the SVCA to generate outgoing positive justification events.
When set to 1, the SVCA generates positive justification events at the rate of one every four
frames regardless of the current level of the internal FIFO. Note that the SVCA will follow up
with an automatic negative pointer justification if it needs to do so in order to keep its FIFO
fill levels under control. The diagnostic feature has a lower priority than the FIFO monitor. In
OC-48c mode (normal mode) this bit should only be set in STS-1 #1 of 48.
Diag_PosJust and Diag_NegJust must not be set to one at the same time. If that occurs, their
operation is disabled.
The Diag_NegJust bit forces the SVCA to generate outgoing negative justification events.
