		Transmission quality is calculated each second as per GR-253
	•	SDH/PDH
		Transmission quality is calculated each second in accordance with recommendations G.826,
		G.828, M.2100, M2101.1, M.2101, M.2110 for performance

Overhead Analysis	•	J0, J1 and J2 Path Trace messages (ASCII sequence)
	•	S1 (synchronization status)
	•	C2/V5 (signal label)
	• Complete display of SOH/TOH and POH of the analyzed path channel
	• Capture capacity: 64 consecutive frames

Event Analysis	•	Alarms and errors event analysis in temporal graphical display with 125 µs resolution

•Measurement possible at each path level
