G= DS1 errors at HLXR are reported as T1-1-X-X-2NEND PM and alarms. Report measures the actual DS1 performance as received on transmission from CSU H.

- OR -

DS1 errors at HLXR are reported as T1-1-X-X-2FEND 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-1NEND PM and alarms. Report measures the actual DS1 performance as received on transmission from CSU A.

- OR -

RLX DS1 input monitors T1-1-X-X-1FEND PM and alarms from CSU A via the PRM in the FDL (Facility Data Link).

G= RLX DS1 input monitors T1-1-X-X-2NEND PM and alarms. This report measures the actual DS1 performance as received on transmit from CSU H.

- OR -

RLX DS1 input monitors T1-1-X-X-2FEND 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. This is due to corrupted data accumulated in the transmission of the DS1 from A to H transmit direction.
