In addition, the DS1 circuit pack hardware applies a DC current while the test is
running in order to detect any broken wires which may not be detected by the
loopback pattern.
When the test is complete, all trunks or ports on the TN767E DS1 Interface circuit
pack are restored to the in-service state after the release board command is
entered.

Error
Code
Test
Result Description/ Recommendation
ABORT Internal system error
1. Retry
t
est ds1-loop PCSS ds1/csu-loopback-tests at 1-minute intervals a
maximum of 5 times.
1005 ABORT CSU Equipment Loopback Test cannot be executed in the current
configuration. To run this test, the
Near-End CSU Type
field on the DS1 circuit
pack administration form must be set to
integrated
and the "Bit Rate" field must
be set to "1.544" (24-channel operation).
1. Use the change ds1 PCSS command to set the
Near-End CSU Type
field
on the DS1 circuit pack administration form to
integrated
, and/or change
the "Bit Rate" field to "1.544" if the board is to be used in the 24-channel
configuration.
2. Retry test ds1-loop PCSS ds1/csu-loopback-tests.
1015 ABORT Ports on the DS1 Interface circuit pack have not been busied out to
out-of-service.
1. Enter the busyout board PCSS command to put all trunks or ports of the
DS1 Interface circuit pack into the out-of-service state.
2. Retry the command.
1039 ABORT The DS1 Interface circuit pack is providing timing for the system. Executing this
test could cause major system disruption.
If the DS1 Interface circuit pack needs to be tested, set the synchronization
reference to another DS1 Interface circuit pack or to the Tone-Clock circuit pack
via the following command sequence:
1. Issue the disable synchronization-switch command.
2. Next, issue the set synchronization PCSS command.
3. Lastly, issue the enable synchronization-switch command.
