G= DS1 errors at HLXR are reported as T1-1-X-X-2 NEND PM and alarms.
Report measures the actual DS1 performance as received on transmission
from CSU H.
DS1 errors at HLXR are reported as T1-1-X-X-2 FEND PM and alarms from
CSU H via the PRM in the FDL (Facility Data Link).
H= External CSU at H will inject PRM back to G reporting DS1 Far End Alarms.
Errors are accumulated in the transmission of the DS1 from A to H transmit
direction.

A= External CSU that will inject PRM (Performance Report Messages) back to B
reporting all DS1 Far End Alarms. This is due to corrupted data received at A
and reported back to B via the PRM in the FDL (Facility Data Link).
B= RLX DS1 input monitors T1-1-X-X-1 NEND PM and alarms. Report measures
the actual DS1 performance as received on transmission from CSU A.
RLX DS1 input monitors T1-1-X-X-1 FEND PM and alarms from CSU A via
the PRM in the FDL (Facility Data Link).
G= RLX DS1 input monitors T1-1-X-X-2 NEND PM and alarms. This report
measures the actual DS1 performance as received on transmit from CSU H.
