If anyincidents are found it willprovide a summary withhyperlinks to more detailedinformation.This will indicate if there is anexisting session, status of thesession, packet counts,duration & IP address.Allows you to batch test up to1000 circuits in one go.This check can run some orall of the Fault Diagnostictests / checks to help with thediagnosis of a fault. It isdependant on the informationsupplied to run the correctseries of tests. As well asdisplaying the results of eachindividual test, it provides youwith Major Finding, Result &Recommendations.This fault diagnostic tool isfor a future development andis not currently available.This fault diagnostic tool isfor a future development andIf you are aware / suspectthere is a BT incidentaffecting other circuits inthat area.You may choose to run thisprior to troubleshooting acircuit, this may help you torule out any common faults.Use this tool to verify if auser is logged in andactively using the service. Astatic (or zero) packetcounter will help indicate ifthere is a stale session.If you need to identify the IPAddress it’s available here.Use the batch test after aknown service outage orwhen dealing with a queueof work e.g. re tests.Use it when you canestablish the correct faultreport code, require help toestablish the cause of theproblem and /or guidanceon the next steps to take toresolve.See ‘One Shot Check FaultType’ Table below for abreakdown of the OSC faultTypesIssue 1: 2006© British Telecommunications plcTHIS IS FOR TRAINING PURPOSES ONLY AND IS SUBJECT TO CHANGE BY BTPage 4 of 10
