Table 17. COLU Alarms (Universal)
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
INSUFFICIENT TIMESLOTS
CR, MJ, MN, NA, NR
Current channel unit configuration has
insufficient timeslots (ISDN only)
MN
RTCU CONFIG MISMATCH
CR, MJ, MN, NA, NR
Incompatible COLU and RTCUs installed,
for example, a POTS COCU is connected
to an ISDN RTCU
MN
COMMON CARD ALARM
CR, MJ, MN, NA, NR
Common Card (PMU/PMX Card) is in
alarm
MN
