Huawei SSN1SL4A(S-4.1,LC) Overview Huawei SSN1SL4A(S-4.1,LC) Board is a 1-channel STM-4 optical interface board, which realizes the reception and transmission of 1-channel STM-4 optical signals, completes the photoelectric conversion of STM-4 signals, the extraction and insertion of overhead bytes, and reports the line. Warning. Support two-fiber multiplex section ring protection, four-fiber multiplex section ring protection, linear multiplex section protection, SNCP protection, SNCTP protection and SNCMP protection. Support MSP and SNCP shared optical path protection. Provides 2 sets of K-byte processing capabilities, and one SL4A board can support up to 2 MSP rings. Supports inner loopback and outer loopback functions at the optical port level.
