Maintenance Objects
3-715ISDN-PLK (ISDN-PRI Signaling Link Port)
3
The actual alarming level depends on the options chosen via the
set
options
command on the G3-MT 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).
f. Bad DLCI error. This error occurs when a LAPD frame is received across
the DS1 facility which contains a DLCI which does not have a valid entry in
the on-board translation memory. This error normally indicates an
off-board problem usually related to a broken endpoint or a state
mismatch between a remote endpoint and the local call processing
software. Maintenance will not start any testing or generate any alarms in
response to this error.
g. Receive FIFO Overflow error. This error occurs when the circuit pack
detects an overflow of its receive buffers. If it occurs frequently, it may
indicate a LAPD parameter mismatch between the two endpoints.
Maintenance does not start any testing or generate any alarms in
response to this error.
System Technician-Demanded Tests: Descriptions
and Error Codes
Always investigate tests in the order presented in the table below when
inspecting errors in the system.
NOTE:
The command line entry to test the ISDN-PLK MO is:
test port PCSSpp (sh
or l)
, where ‘pp’ is ‘24’ for 24-channel interfaces, and ‘16’ for 32-channel
interfaces.
Signaling Link Board Check (#643)
This test checks the state of the UDS1 Interface circuit pack (TN464C or later)
transporting the ISDN-PRI Signaling Link.
