T L1 Alarm Description
The access identifier (CBA slot)
has a major service-affecting
alarm because of a loss of sync
condition on the HDSL loops or
loss of signal at the HTU-R DS1.
The access identifier (CBA slot)
has a major service-affecting
alarm because no channel unit is
installed in an equipped CBA slot.
The access identifier (CBA slot)
has a major service-affecting
alarm because of equipment type
mismatch.
The access identifier (CBA slot)
has a major service-affecting
equipment failure.
Implications
There is an HDSL loss of sync in any
HDSL leg, or DS1 loss of signal at the
HTU-R DS1 interface. The HTU-C is in
startup ,or a problem exists on the
local loop or customer interface.
No channel unit is installed in a slot
which should be equipped. The
HTU-C is not inserted properly in the
correct slot, or the unit is defective.
The equipment installed in the chan-
nel bank slot differs from the equip-
ment type reserved in the software
record of the Litespan database. To
clear the alarm delete the equipment
record (for example, dlt-eqpt::cot-1-15
with TL1) and reinsert the card, or
equip the slot with the currently
reserved equipment type.
The HTU-C NB/WB for Litespan is
unable to operate normally or has
failed a diagnostic test. Refer to the
"Troubleshooting" section of this
practice.
