OSN3500 ইকুইপমেন্ট লাইন বোর্ড নামকরণের নিয়ম

For example OSN3500 SLQ16 optical interface board

• The first letter “এস” SDH এর অর্থ, which means that the STM-N signal is output/input.

• The second letter “L” stands for Line, indicating that it is a line board.

• The third letter “প্র”: is the first letter of Quarter, which stands for 4, which indicates that this board supports the line output of 4 STM-N signals.

• The other letters “ডি” are the initials of Dual, which stands for 2, which indicates that the board supports the line output of 2 STM-N signals, such as SLD4.
• “ও” is the first letter of Octet, which stands for 8, which indicates that this board supports 8 line output of STM-N signals, such as SLO4.
• “টি” is the first letter of Twelve, which stands for 12, indicating that this board supports 12 line output of STM-N signals, such as SLT1.
• “এইচ” is the first letter of Hex, which stands for 16, which indicates that this board supports the line output of 16 STM-N signals, such as SLH1.
• If the third letter does not have any letters, such as the SL16 board, it means that the board supports 1 line of STM-N signal line output.
• The fourth number “16” represents the signal rate is STM-16.
• Other numbers, যেমন 64 for STM-64; 4 for STM-4; 1 for STM-1
• Other boards, such as SL1, SLQ1, SLO1, SL4, SLD4, SLO4, SL64, ইত্যাদি. all follow this rule.
• If it is an SF64 single board,
• F stands for FEC function. Also 64 stands for STM-64. S stands for SDH. Other boards, such as SF1 6, follow this rule.
• If it is SEP1 when it is used as a circuit board.
• S stands for SDH, E stands for electrical, P stands for the process, এবং 1 stands for STM-1. Its function is to complete the processing of two STM-1 electrical signals.
