OSNR Margin (Optical Signal-to-Noise Ratio Margin) is a critical parameter in optical communication systems that measures the difference between the actual OSNR and the minimum OSNR required for error free signal detection (typically defined by a bit error rate threshold). It provides insight into how much "headroom" or tolerance a system has before it fails to maintain acceptable performance. š‡šØš° š¢š­ šœššš§ š›šž šŒšžššš¬š®š«šžš=> OSNR Margin=Actual OSNR−Required OSNR š‘°š’Žš’‘š’š’“š’•š’‚š’š’„š’†: Indicates the system's robustness against impairments like noise, dispersion, and nonlinear effects.

ALARM GLOSSARY

  Glossary Abis Interface between Base Transceiver Station (BTS) and Base Station Controller (BSC). Abis Configuration Configuration of traffic channels (OMUSIG, TCH, TRXSIG) on Abis. Abis Protection Scheme used to provide redundant Abis Traffic across a separate path to guard against possible link failure. Automatic Connection Feature in 2G Flexi BTS Site Manager, which would allow the user to get connected to the BTS automatically once BTS Manager is launched. The parameters required for connection viz. the BTS IP Address, the port of connection and the Q1 address will be taken from the locally stored defaults. 'Automatic Connection' would be an optional feature that the user may enable or disable anytime. BBU Battery Backup Unit. The Battery Backup Unit gives a power supply in case of a temporary mains power supply breakdown. BCF Base Control Function Base Control function is a functional entity that handles common control functions e.g. main clock functions, external alarm ...
