Overview

Learn how to install, activate, configure, test and troubleshoot a T1/T3 network.

By participating in this training seminar, you will:

• Master the fundamentals of T1, T3 and SONET
• Build and operate a full end-to-end T1 facility at each workstation
• Evaluate T1 voice and data interface options, applications and performance criteria
• Monitor framing and signaling formats, verify T1 signaling
• Discuss the technical, financial and operational differences between implementation of Fractional T1, T3 and other WAN and access technologies
• Master the five main T1/T3 activities - installation, activation, acceptance testing, troubleshooting and network synchronization
• Identify and resolve system failures on a fully operational T1 network
• Develop troubleshooting skills in 3 main problem areas- Span, demarcation and customer premises equipment
• Isolate problems methodically and eliminate "finger pointing"
• Understand the meaning of various alarms and what action to take to resolve problems

Who Should Participate

Hands-on Labs

Lab 1: Install a T1 circuit from demarcation point through local distribution wiring to a CSU.

Lab 2: Use test equipment to see signaling states and T1 framing conditions.

Lab 3: Configure station equipment-option DTE.

Lab 4: Perform loopback tests through system components.

Lab 5: Use test equipment to verify various failure conditions found on in-service spans.

Lab 6: Perform Bellcore standard acceptance tests on T1 circuits.

Lab 7: Verify correct framing options.
