DS1-BD (DS1 Interface Circuit Pack)
Issue 4 May 2002 10-617 555-233-123
f. The DS1 Interface circuit pack has detected a transient hardware problem
(for example, external RAM failure, internal RAM failure, internal ROM
failure, or instruction set failure). This error will disappear when no faults
are detected for 30 minutes. The value in the Aux Data field indicates the
type of hardware problem. However, when this error is reported with Aux
Data in the range of 4352 to 4358, it indicates the circuit pack has reported
a hardware failure. Escalate this problem.
g. The DS1 Interface circuit pack has detected a transient hardware logic
error (for example, program logic inconsistency). This error will disappear
when no faults are detected for 100 minutes. The value in Aux Data field
indicates the type of hardware problem.
h. CSU Module or T1 Sync Splitter missing. The
Near-End CSU Type
field
on the add ds1 form has been administered as
integrated
but the
120A1 CSU Module or T1 Sync Splitter is not physically connected (or is
improperly connected) to the TN767E board on the back of the port carrier.
If using the 120A1 CSU Module or T1 Sync Splitter, plug (or replug) the
CSU Module/T1 Sync Splitter into the TN767E circuit pack’s connector on
the I/O connector panel on back of the carrier. Otherwise, change the
Near-End CSU Type
field using the change ds1 form to
other
.
If this error remains after plugging the CSU Module/ T1 Sync Splitter into
the board’s connector, there could be a problem with the I/O connector
panel.
i. CSU Module/T1 Sync Splitter not expected. The 120A1 CSU Module/T1
Sync Splitter is physically connected to the TN767E board on the back of
the port carrier but the
Near-End CSU Type
field on the add ds1 form
has not been administered as
integrated
.
If the 120A1 CSU Module/T1 Sync Splitter is to be used, use the change
ds1 command to change the
Near-End CSU Type
field to
integrated
.
Otherwise, physically remove the 120A1 CSU Module/T1 Sync Splitter
from the back of the port carrier.
j. DS1 configuration error. Attempting to use the 120A1 CSU Module with a
TN767E circuit pack that is configured for 32-channel (2.048 Mbps)
operation. The CSU Module only works with a DS1 board configured for
24-channel (1.544 Mbps) operation in the United States of America.
k. DS1 circuit pack suffix incorrect for CSU Module/T1 Sync Splitter. The
Near-End CSU Type
field on the add ds1 form has been administered
as
integrated
but the DS1 circuit pack is not a TN767E or later suffix
DS1 board.
If the 120A1 CSU Module/T1 Sync Splitter is to be used, remove the circuit
pack and replace it with a TN767E or later suffix board. Otherwise, use the
change ds1 command to change the
Near-End CSU Type
field to
other
.
