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.
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 indicates 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 PCSS end-loopback/span-test command in order to execute this 
test.
1951 ABORT The CSU Repeater Loopback Test could not be executed because the 120A 
CSU Module was not physically installed. Physically connect the 120A1 CSU 
Module to the TN767E board on the back of the port carrier.
