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 
PCSS end-loopback/span-test
 command in order to 
execute this test.
