SDBER - Signal Degrade Bit Error Rate: A high SDBER rate indicates an issue with the physical layer of a connection causing errors with received bits/data.
BIP - Bit Interleaved Parity: BIP is a technique used to detect bit errors by calculating parity bits over specific portions of the data stream. When the received BIP value doesn't match the locally calculated BIP value, it signifies a bit error within that data segment
