Hardware Error Log Entries and Test to Clear
Values
Notes:
•
The D-channel is demand busied out. No calls can be made over this D-channel.
•
This Error Type indicates that the Media Module has been removed or has been insane for more
than 11 minutes. To clear the error, reinsert or replace the Media Module.
•
Link error. This error occurs when the port receives an invalid frame over the D-channel. This
error normally indicates an off-board problem usually related to transmission errors on the DS1
facility. Execute
list measurements ds1-log
for the MM710 Media Module on which the D-
channel resides. If the MG-DS1 is reporting some errors, then the DS1 facility has experienced
transmission problems which could have caused the ISDN-LNK to report a Link Error.
If the MG-DS1 is not reporting errors, execute the long test sequence for the D-channel.
Investigate any errors. If there are none, execute a long test sequence for the MM-DS1 Media
Module. Investigate any errors.
If no errors could be found by testing, the Link Error is probably not affecting service. However,
if this Link Error continues to be logged, follow normal escalation procedures.
•
MG-DS1 Interface Media Module is out-of-service. Look for and resolve DS1-BD errors in the
Hardware Error Log.
•
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.
