First, the nomenclature matters:
The A15 is a 15-slot service board (often 16 ports, but the "15" denotes hardware revision/traffic capacity). It does not work alone. It plugs into a ZTE B820C chassis backplane, which handles power, cooling, and fabric switching.
Key role: It converts Ethernet/IP traffic from the core network into GPON (Gigabit Passive Optical Network) frames, then transmits them down a single optical fiber to up to 64-128 subscribers via a passive optical splitter. Zte Zxv10 B820c-a15
The Amlogic S905X is a legendary chip for a reason. It handles hardware decoding of H.265 (HEVC) effortlessly. This means:
