All productsCIUA, Huawei MA5800 OLT combo interface transfer board, provides the input and output clock source for the system and supports functions such as input and output of alarm digital parameters, supports versions of H901CIUA, H902CIUA, H906CIUA and H907CIUA.
MA5800 X7, X15 and X17 main control board includes MPLA, MPLB, MPLG, etc., and their daughter board includes CKUA, CKUB, CKUF, etc.
To realize clock processing and provides the stratum-3 clock, and 1588v2 clock processing function for the system, MPLA or MPLB with its daughter board must work with CIUA, and different versions and boards are different mappings, below is the mapping list of the 3 boards.
