Table 16. COLU Alarms (Integrated)
Alarm Value Description Default
DSL POWER FAULT CR, MJ, MN, NA, NR DSL Power Fault MN
DSL POWER FEED OPEN CR, MJ, MN, NA, NR COLU cannot power the RTLU due to an
open circuit. A possible cause is that
there is no RTLU at the other end of the
circuit. No user intervention is required.
MJ
DSL POWER FEED SHORT CR, MJ, MN, NA, NR COLU cannot power the RTLU due to a
short circuit. A PFS alarm indicates an
overcurrent condition due to wire shorting
or an RTLU failure. COLU automatically
turns off power feeding both loops in
response to a PFO or PFS condition on a
single loop.
MJ
DSL POWER GROUND FAULT CR, MJ, MN, NA, NR Ground fault detected on HDSL loop MJ
HDSL PAYLOAD SYNC CR, MJ, MN, NA, NR HDSL payload is out of synchronization MJ
NO RTLU S/W CR, MJ, MN, NA, NR RTLU has no application software and is
awaiting software download
MJ
LOW TEMPERATURE CR, MJ, MN, NA, NR Temperature at RTLU is too low MN
HIGH TEMPERATURE CR, MJ, MN, NA, NR Temperature at RTLU is too high MJ
EEPROM FAILURE CR, MJ, MN, NA, NR A checksum error has been detected on
COLUs EEPROM data
MN
COLU-RTLU MISMATCH CR, MJ, MN, NA, NR Incompatible COLU and RTLUs installed,
for example, an incompatible RTLU List
Number is installed
MJ
CO BATTERY A CR, MJ, MN, NA, NR COLU detected missing A -48 V power
source. If power is verified at the unit,
then the unit must be replaced, because
it has a blown fuse.
MN
CO BATTERY B CR, MJ, MN, NA, NR COLU detected missing B -48V power
source. If power is verified at the unit,
then the unit must be replaced, because
it has a blown fuse.
MN
INVALID SLOT CR, MJ, MN, NA, NR RTCU installed in an invalid slot MJ
MUX PARITY CR, MJ, MN, NA, NR Errors are detected between the COLU
and the PMX
MJ
