H31-341_V2.5 Exam Dumps : HCIP-Transmission V2.5

The TNG2M60V board is not a 60-channel multiplexer with VOA for the Super C band; this description is incorrect for that board model.

Alarm handling differs between OTN and SDH encapsulation processes, so they are not processed in the same way when GE services are mapped into OTN versus SDH signals.

In an OA (Optical Amplifier) system, the lower threshold of the receive optical power for a line board with a PIN receiver or the WDM side of an OTU board is typically the optical module’s receiver sensitivity plus 3 dB, not 5 dB. Adding 3 dB accounts for margin to ensure reliable reception without unnecessary overdesign. The 5 dB margin usually applies when an APD receiver is used, which is more sensitive but also more susceptible to noise. Thus, for PIN receivers, HCIP-Transmission guidelines specify the lower threshold as sensitivity plus 3 dB to maintain signal quality while preventing false alarms or unnecessary protection switching.
