It comes just as that. We work in a remote center/NOC where this message would come from a PBX that is monitored by a SEB and supporting equipment to collect the alarms. We haven't been able to find any info from Nortel documents as well. The people in charge of programming the SEB's claim it nothing to do with the Seb itself. So we are kinda at a lost ourselfs. The Beb is not programmed to report any audit, bug, sch, or info errors so I don't know what is printed along with this error. This happens infrequently but enough to raise the question.
