  If the LG-Ericsson PBX system experiences a power failure, first ensure the fuse/breaker is working and AC power is reaching the outlet. Check the PSU fuse and LD21, LD22 on the backplane; replace the PSU if needed. Also verify the MPB is installed and check for short circuits by removing boards one at a time from the KSU. Finally, check the DC output status on the MB if LD4 LED is off on the MPB.

  If your LG-Ericsson PBX DKT does not operate, replace the malfunctioning board if it is a bad DTIB circuit. Check the connection between the DSIU/DTIB and DKT terminals, ensure proper wiring, and repair any broken connections. Also, ensure the distance between the board and DKT does not exceed specifications. If the DKT is bad, plug it into a verified working extension port; if it still fails, replace the DKT.

  If you experience noise on the external MOH and paging port of your LG-Ericsson PBX, ensure the wiring is not near equipment generating high RF interference and contains no coils. Use shielded pair wiring and ground the shield. Also, decrease the output level of the external music source if the input level is excessive.
