ISDN-LNK (ISDN-PRI Signaling Link Port)
Issue 4 May 2002 10-937 555-233-123
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.
NPE Crosstalk Test (#6)
The NPE Crosstalk Test verifies that this port’s NPE channel talks on the selected
time slot and never crosses over to time slots reserved for other connections. If
the NPE is not working correctly, one-way and noisy connections may be
observed. This test is usually only part of a port’s Long Test Sequence and takes
about 20 to 30 seconds to complete. This test runs only if the Processor Interface
link corresponding to this ISDN-LNK MO is busied out by system technician. The
Processor Interface link number can be determined from the
Communication-Interface Links form.
