QSIG OverviewFor more information onETSI specifications, referto page xxx.For more information onobject identifiers insupplementary services,see page 2-10.QSIG is a type of ISDN that is based on the ITU-T Q.931 standard. Ituses ROSE encoding and object identifiers for its varioussupplementary services. While the identifiers can be coded fromstandards produced by ISO, ECMA, or ETSI, the Intervoiceimplementation uses ETSI standards.The QSIG call control is defined in ETSI specifications EN 300 171 andEN 300 172. The switch type is defined in the configuration file, sincevarious switch vendors may vary in their methods of implementation.The Path Replacement type of call transfer is defined in ETSIspecifications ETS 300 258 and ETS 300 259. Path replacement is asupplemental service that uses two lines, a primary line and an outboundline.QSIG ConsoleThe QSIG Console utility, qsig_con.exe, allows the user to makeconfiguration changes, adjust timer periods, enable lines, and generatelog files of the QSIG messages.For more information onQSIG Console, refer to“ISDN Console,”Chapter 14.QSIG logs are stored in the intv\dat directory and named qsiglog.dat.These logs are binary files that must be converted into text format withthe RDISDN Reader Program. To convert a log file, enter the followingcommand:Rdisdn This program can be run from any directory and stored in any filenameyou choose.5-2 ISDN Protocol Administrator’s and Developer’s Guide 60001262, First Edition
QSIG OperationQSIG OperationIn the flowchart, yellowareas indicate ISDNmessage traffic createdduring the life of a call.White areas are basic callflow data.QSIG functionality is illustrated in the flowcharts on the followingpages. The binary data message contents are taken from an actual QSIGtransfer, but are presented here for general reference only. Actualmessage content may vary slightly because of differing Call ReferenceValues or other switch-dependent optional elements that may appear.Figure 5-1 displays a single-step transfer.Inbound Call ToOmvia MediaServerRSetup00010000080200010504038090A31803A983816C0C018039373233313831323334700B8138313735353131323132TTTRCall Proceeding0201000208028001021803A98381Alerting020102020802800101Connect020104020802800107Connect Ack00010206080200010FCall Answered ByApplicationToolkit CallISDN_QSIG_SINGLE_STEP_XFERTFacility - Request Switch To Transfer Call0201060408028001621C4091AA068001008201008B0100A11F0202259006062881980400633024A00C120A39373234353438353535A011A00F120A383137353531353932340A0100010100TransferSuccessful ?NOHandle Failure InApplicationYESRTRDisconnect00010408080200014508028090Release02010806080280014DRelease Complete0001060A080200015A08028090Transfer CompleteApplication HasDisconnectedFigure 5-1.
