Figure
A1= External CSU that will inject PRM (Performance Report Messages) back to B1 reporting all DS1 Far End Alarms. This is due to corrupted data received at A1 and reported back to B1 via the PRM in the FDL (Facility Data Link).
B1= QLX DS1 input monitors
G1= QLX DS1 input monitors
H1= External CSU at H1 will inject PRM back to G1 reporting DS1 Far End Alarms. This is due to corrupted data accumulated in the transmission of the DS1 from A1 to H1 transmit direction.
Note: Ax indicates DS1 #1 of four possible DS1s.
