1039 ABORT The UDS1 Interface circuit pack is providing timing for the
system. Executing this test could cause major system
disruption.
If the UDS1 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 using 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 120A1 CSU Module or the 401A T1 Sync Splitter
was not physically installed. Physically connect the 120A1 CSU
Module or the 401A T1 Sync Splitter to the UDS1-BD board on
the back of the port carrier.
