Beskrivelse This course focuses on how to troubleshoot the Cisco PGW solution with the PGW operating in Call Control mode. The attendees will spend their time in theory/lab sessions learning various Cisco and generic commands and tools e.g. Show and Debug on IOS devices, PGW/HSI mml and Solaris CLI commands, Call Tracing on the PGW and HSI, Flow Analysis with Wireshark-, Cisco PTC-MT-, MDL-, Solaris Snoop protocol analyser and retrieving logs and alarms in order to troubleshoot.
The course will concentrate on the following call elements: PGW, HSI, AS5350 Universal Gateway with Integrated SLT, ITP, CSPS, IOS Voice Gateway, CCM and various endpoints. The course will replicate the following call scenarios for investigation: TDM (SS7, ISDN) to TDM, TDM (SS7, ISDN) to VoIP (H.323, SIP, EISUP), VoIP to VoIP.
This course provides the knowledge and skills required to troubleshoot PGW/HSI systems and IP network deployments, addressing both design/planning practices and hands-on experience troubleshooting. Attendees should be encouraged to use their own PC/laptop resource including packet analyser to capture configurations and packet traces.
