Monitored qualitative parameters of E2 optical interface

TM-77 and MD-77 devices are provided with a function of qualitative parameter monitoring.
The devices automatically monitor the linear interface signal parameters and detect, count
and signalize the following conditions and parameters:
• LOOS
• LDF
• LOF
• 10E-3
• 10E-6
• RAL
• ES15
