The ICB provides enhanced message handling that includes the 
following:

•

Fixed message format and unique message codes.

•

Categorization of messages by severity.

•

Message analysis tool that provides on-line documentation. 

•

Message filtering based on such items as severity and firmware 
component. 

•

Advanced troubleshooting.

Note:  Since the on-line documentation is always available and 
accurate according to the cards firmware version, this guide does not 
document specific error messages.

The general format of error messages is as follows:

<serial number> <severity> <error code> <timestamp> <error text>

Table 48 describes the error message fields.

 

<serial number>

Four digits that provide a sequence for the messages. It starts at 0001 at 
power-up and increments by one for each message issued. It wraps around 
when it reaches 9999.

<severity>

Severity levels are as follows:

CRITICAL – indicates immediate corrective action is required (for example, the 
application cannot continue and/or the card must be restarted).

MAJOR – indicates urgent corrective action is required (for example, the BUI 
doesn’t work, but call processing continues to operate).

MINOR – indicates the existence of a fault condition; corrective action should be 
taken to prevent a more serious fault. For example, a problem affecting a single 
channel is minor, so long as the system is still fully operational.

WARNING – indicates a low level failure that almost does not impact a 
customer. No corrective action is required, because auto-recovery is performed. 
Frequent appearance can indicate a more serious problem.

INFO – shows normal operational event notifications (for example, state 
changes in hardware or software; time and date changes).

DEBUG – for use by designers only.
