PERFORMANCE MONITORING REPORTING LOCATIONS
Summary: Performance Monitoring (PM) information for both DS1 and HDSL is found on the
MPU's main menu under Performance Monitoring. The following information is designed to
show where the PM information is being reported from (that is, Near End [NEND] and Far End
[FEND] PM report locations). Refer to
system. Refer to Figure 103-2
Figure 103-3 for a drawing of the Soneplex Optical DS2 (QLX) system.

A= External CSU that will inject PRM (Performance Report Messages) back to B
reporting all DS1 Far End Alarms. Errors or problems received at A are
reported back to B via the PRM in the FDL (Facility Data Link).
B= DS1 errors at HLXC are reported as T1-1-X-X-1 NEND PM and alarms.
Report measures the actual DS1 performance as received from CSU A.
DS1 errors at HLXC are reported as T1-1-X-X-1 FEND PM and alarms from
CSU A via the PRM in the FDL (Facility Data Link).
C= HDSL errors at HLXC are reported as HDSL-1-X-X-1 (Loop 1) or HDSL-1-
X-X-2 (Loop 2) NEND PM and alarms.
D= HDSL errors at HRX are reported as HDSL-1-X-X-1 (Loop 1) or HDSL-1-X-
X-2 (Loop 2) REPR PM and alarms at HRX on CO side.
E = HDSL errors at HRX are reported as HDSL-1-X-X-1 (Loop 1) or HDSL-1-X-
X-2 (Loop 2) NEND PM and alarms at HRX (REPC) on CPE side.
F = HDSL errors at HLXR are reported as HDSL-1-X-X-1 (Loop 1) or HDSL-1-
X-X-2 (Loop 2) FEND PM and alarms.
