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 Figure 103-1 for a drawing of the Soneplex HDSL
system. Refer to Figure 103-2 for a drawing of the Soneplex T1 Repeater (RLX) system. Refer to
Figure 103-3 for a drawing of the Soneplex Optical DS2 (QLX) system.
