Which two statements about a SmartJack are true? (Choose two.)

The correct answer is A. It provides signal conversion. E. It regenerates the signal to compensate for signal degradation from line transmission. Signal Conversion: SmartJacks can convert between different signaling types (e.g., AMI to B8ZS). This is necessary because different telecommunication lines may use varying signaling standards.exclamation. Signal Regeneration: As signals travel over long distances, they can…

Explanation

Signal Conversion: SmartJacks can convert between different signaling types (e.g., AMI to B8ZS). This is necessary because different telecommunication lines may use varying signaling standards.exclamation. Signal Regeneration: As signals travel over long distances, they can weaken and degrade.expand_more SmartJacks help regenerate the signal, ensuring that it maintains its strength and integrity throughout the transmission.
