## Detailed Description

MOST\_LIGHTLOCK.

This event refers to the optical or electrical modulated signal at the transceiver's Rx.

"Signal On" means that a modulated signal has been detected.

"Lock" means that the receiver PLL (Phase Locked Loop) was able to establish synchronization with the phase of the modulated signal (to "lock").

"Stable Lock" means that for a certain period of time no unlock occurred (see MOST specification).

In case of a series of unlocks, the time of the different unlocks are accumulated. If this accumulated time is greater than a certain threshold, it is called "Critical Unlock" (details see MOST specification).
