4. The LPT (Link Pass Through) function is used in scenarios where WDM equipment accesses FE/GE/10GE LAN services. The correct statement about LPT is: (multiple choice)
A) It enables the user equipment to perceive the link status information by turning off and turning on the laser of the wavelength division device, thereby triggering the user equipment to activate the business protection function, and select the main or backup link for communication
B) The implementation of the LPT function can be divided into port-based LPT and service-based LPT.
C) From the network level, ALS is similar to the Link Pass Through (Link Pass Through) function. The difference is mainly reflected in the applicable services, fault transmission methods and laser restart mechanism.
D) By adding overhead bytes supporting the LPT protocol to the WDM side signal frame format, the operating status of the network access point or service network can be monitored.
