Most Ethernet data boards support the LCAS function. Based on software versions, data boards can support the LCAS function of two versions: LCAS V1.0 and LCAS V2.0.
The LCAS V2.0 is the Ethernet feature developed by the NG-SDH V100R006 and OSN 9500 V100R004.
At present, most of the OSN series boards, including the SSN1EFT8, SSR1EFT4, SSN1EGT2, SSN1EFT8A, SSN4EFS0, SSN2EFS4, SSN2EGS2, SSN1EMS4, SSN1EGS4, and the SSJ2EGT6 have been switched to the LCAS V2.0.
SSN1EFS4/SSN2EFS0 support the LCAS V2.0. However, it provides the operation interface for the LCAS V1.0 rather than the supplementary function.
No version of the SSN1EFS0 supports LCAS V2.0. To support LCAS V2.0, the SSN1EFS0 board must be upgraded to board SSN2EFS0 or SSN4EFS0 of the version that supports LCAS V2.0
Due to poor stability of LCAS V1.0 and users’ incorrect operation, the NMS does not provide the LCAS V1.0 function by default.
