TNV4SXCL, 160G VC3/VC12 Low Order Universal Cross-connect Board
Applied to Huawei OSN 9800 U32 OSN9800 U64 and OSN 9800 M24
It is a cross-connect board that implements VC-3 and VC-12 signal grooming and protection in a subrack
Two SXCL boards, which work in active and standby mode, must be configured for each subrack
Lower-order cross-connections can be configured only after two lower-order cross-connect boards are added. In addition, 1+1 protection of the two lower-order cross-connect boards is automatically created
The lower-order cross-connect boards can be deleted only after all lower-order cross-connections are deleted
TNV4SXCL extracts VC-3 and VC-12 signals from VC-4 signals and performs electrical-layer grooming on all VC-3 and VC-12 signals. After the grooming is completed, the SXCL board encapsulates the signals into VC-4 signals again. The UXCS/UCXCS/CXCS/CXP board then transmits the VC-4 signals to service boards. In this way, grooming of VC-3 and VC-12 signals is completed.
