• SDH: STM-0, STM-1, STM-4, STM-16, STM-64 (ITU-T G.707 compliant)
• SONET: OC-1, OC-3, OC-12, OC-48, OC-192 (Telcordia GR-253-CORE compliant)
• Frame formats: Standard and add/drop multiplexing configurations
• Payload types: PDH, Ethernet, ATM, and additional formats
Error and Signal Analysis:
• Bit error rate (BER) measurement at section, line, and path overhead levels
• Jitter and wander measurement per ITU-T and Telcordia standards
• Pointer adjustment analysis for synchronization verification
• Overhead byte visibility and manipulation (A1, A2, J0, J1, C2, etc.)
• Tributary-level testing and isolation
• Payload content verification including tributary signal mapping and de-mapping
Signal Generation:
• Configurable standard test patterns
• Programmable impairments: bit errors, signal fading, clock slips
