Error Log Entries and Test to Clear Values
Notes:
a. Indicates that the circuit pack has been removed or has been insane for 
more than 11 minutes. To clear, reinsert or replace the circuit pack.
b. The actual alarming level depends on the options chosen via the set 
options command on the Manager terminal. ISDN-PRI Signaling Link Port 
alarms are treated as Station alarms, and their default alarming option is to 
downgrade all alarms to Warning. The value shown in the preceding table 
indicates the normal, unfiltered case (option "y" on the Set Options form).
c. ’pp’ is ’24’ for 24-channel interfaces, and ’16’ for 32-channel interfaces.
System Technician-Demanded Tests: 
Descriptions and Error Codes
Always investigate tests in the order presented in the table below. By clearing 
error codes associated with the 
NPE Crosstalk Test
, for example, you may also 
clear errors generated from other tests in the testing sequence. The command 
line entry to test the ISDN-LNK MO is: test port PCSSxx (sh or l), where ‘xx’ is 
‘24’ for 24-channel interfaces, and ‘16’ for 32-channel interfaces.
1. Run the short test sequence first. If all tests pass, run the long test sequence. Refer to the 
appropriate test description and follow the recommended procedures.
