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 UUCSS command.
3. Lastly, issue the enable synchronization-switch command.
1950 ABORT Another loopback/span test is already executing on the DS1
board or the board is in a network requested loopback mode (Line
loopback or Payload loopback). The hardware error log will
indicate whether a Customer Loopback Jack Test, Far CSU
Loopback Test, or the One-Way Span Test is executing or if the
board is in line loopback or payload loopback mode. Only one
long-duration loopback/span test can be active at a given time.
Thus, if a loopback/span test is already active, that test must be
terminated via the test ds1-loop UUCSS
end-loopback/span-test command in order to execute this test.
1951 ABORT The CSU Equipment Loopback Test could not be executed
because the 120A CSU Module/T1 Sync Splitter was not
physically installed. Physically connect the 120A CSU Module/T1
Sync Splitter to the TN767E board on the back of the port carrier.
ABORT Internal system error
2100 ABORT Could not allocate the necessary system resources to run this
test.
1. Retry the command at 1-minute intervals a maximum of 5
times.
