TUC (Troubleshooting Cisco Unified Communications Systems)
Duration
Five Days
Overview
Cisco Course v1.0 | CallManager Software v4.1x and v5.x| Prepares you for Cisco Exam 642-426 TUC.
This course equips network professionals with the knowledge and skills required to troubleshoot Unified Communications systems/solutions in enterprise, mid-market, and commercial deployments. Learn troubleshooting methodology, triage, resources, tools, and fixes at the integrated system/solution level as well as for components, such as Cisco Unified CallManager, Cisco Unity, videoconferencing, and network infrastructure.
Why take TUC?
We offer a unique, real-world TUC lab environment that teaches you how to troubleshoot a sophisticated IP telephony network based on best practice recommendations for a real deployment. We have set ourselves apart from other Cisco training providers by enhancing our TUC hands-on labs to include a real dial plan, the latest recommendations for Class of Service (CoS) for calling out to the PSTN, branch offices, PBXs, and fault-tolerant gatekeeper and directory gatekeeper deployments. No other training company offers a unique, real-world lab solution like ours.
Our voice network labs use the latest hardware and software.
- Troubleshoot Cisco's new ISR routers: 2811s are used throughout the network
- Gain experience with recent stable IOS release: 12.3.14T3
- Configure CallManager 4.x and 5.x
- Explore router DSP configuration: PVDM2-32 cards in every 2811 router
- Every router has 2xFXS, 2xFXO, and 2xT1 ports (PRI and T1-CAS) as well as serial ports for WAN connectivity
- All of the latest tools are deployed on the laptops for analyzing traces
- All laptops have sniffers installed
All of our IP telephony courses provide a simulated PSTN.
- Deploy Cisco CallManager 4.x and 5.x
- Every pod has internal and external phones
- Build and test a real dial plan including:
- 911
- 3-digit service codes: 411, 511, etc.
- 7-digit local numbers: 681-1901
- 10-digit local numbers: 416-681-1901
- 11-digit long distance numbers: 1-733-802-1901
- International numbers: 011441902
And just like in a real network:
- The same simulated PSTN is accessible through both PRI and FXO ports
- The same simulated PSTN is accessible through all four clusters providing failover scenarios for bandwidth and connectivity problems
- Different area codes are deployed at all sites (two per cluster)
You will troubleshoot a network with the following features:
- Four CallManager clusters deployed: two students are responsible for each cluster
- Each cluster has a Headquarters (HQ) and Branch router in different area codes
- The Headquarters router is MGCP controlled
- The Branch router is H.323 controlled
- Both HQ and Branch have 2 PBXs attached via T1-CAS
- Clusters are connected via gatekeeper-controlled ICTs
- Gatekeeper clusters and fault tolerant directory gatekeepers are deployed
- SRST is fully deployed on all routers
- COR is fully deployed on all routers
- Hardware and software resources are deployed for conferencing
- Transcoding resources are deployed
What You'll Learn
- A systematic methodology to troubleshoot Cisco Unified Communication systems by using knowledge of tools and reports that help isolate Cisco Unified Communication system problems
- When given a trouble call that has been categorized as a Cisco Unified CallManager-related issue, isolate the specific problem, propose a solution, and, where appropriate, implement the solution
- Diagnose and resolve a call setup issue
- Troubleshoot the quality of both voice and video streams
- Given a trouble call that has been isolated to a Cisco Unified Communications system component application, isolate the specific problem, propose a solution, and, where appropriate, implement the solution
Who Needs to Attend
System engineers, field engineers, and anyone attempting the CCVP certification that includes IP Telephony Troubleshooting would benefit.
