𝐖𝐡𝐚𝐭 𝐢𝐬 𝐎𝐒𝐍𝐑 ? & 𝐇𝐨𝐰 𝐢𝐭 𝐜𝐚𝐧 𝐛𝐞 𝐌𝐞𝐚𝐬𝐮𝐫𝐞𝐝? 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. 𝐇𝐨𝐰 𝐢𝐭 𝐜𝐚𝐧 𝐛𝐞 𝐌𝐞𝐚𝐬𝐮𝐫𝐞𝐝=> OSNR Margin=Actual OSNR−Required OSNR 𝑰𝒎𝒑𝒐𝒓𝒕𝒂𝒏𝒄𝒆: Indicates the system's robustness against impairments like noise, dispersion, and nonlinear effects. Higher OSNR Margin means the system is more resilient to degradation over time or due to network changes.

Nokia BSC Commands

  Nokia BSC Commands These commands use for Nokia BSC & MSC. Hot Keys: Ctrl + B repeats last and previous commands on the MML Ctrl + Y interrupts current command being typed or run Alarm monitoring: ZAHO; displays current active alarms in actual MSC and BSC only ZEOL:#; displays active alarms on BCF (BCF = Site Manager or CF) ZEEI:BCF=#; displays the operational state of the site ZEOH:date,time:BCF=#; displays alarm history for site for the date and time listed ZAHO:ET,#; displays current alarms for that ET (PCM) ZAHP:ET,#; displays alarm history for that ET ZEEL:BL; displays locked Sites, Sectors and TRXs on BSC Investigating Clear Codes: ZTUT:CLR; displays current clear codes on the MSC ZTUL:CLR; displays latest history of clear codes Canceling Bogus alarms on a Site: (Perform both commands) ZEOR:#:alarm #; cancels alarm on site ZEFR:#:OMU; resets the OMU (Operations and Maintenance Unit) Canceling Bogus alarms on a BSC: ZACC:####; cancels the alarm using the consecutive # in...

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 ...
