Legacy Telephony Line Characteristics

This area discusses running the characteristics of the analog telephone line: voice channel, telephone line characteristics, attenuation distortion, propagation delay, envelope delay distortion, line impairments, crosstalk, echo or signal return, frequency shift, non-linear distortion, jitter and transients.

Voice Channel - The Voice Channel is the basic building block of the legacy telephony network. It is an analog channel with specific bandwidth characteristics.

Signal Errors - This area discusses errors that affected or interfere with the signal: These include crosstalk, echo or signal return and frequency shift.

Distortion - This section discusses faults which distort the original signal: non-linear distortion, attenuation distortion and envelope delay distortion.

Time Errors -This area discusses errors that are related to timing and consists of propagation delay, jitter and transients.
