The DC908 does not explicitly support SCC (System Control Card) 1+1 redundancy, per HCSA-Sales-Transmission & Access. While it offers hardware reliability, SCC redundancy is more associated with OLTs (e.g., EA5800), not DCI-focused DC908, making the statement FALSE.
Passive Optical LAN (POL) is an all-optical enterprise networking solution comprising Optical Line Terminals (OLT) and Optical Network Units (ONU). In office scenarios, Huawei’s Campus OptiX POL solution allows flexibility in deployment. Official HCSA-Sales-Transmission & Access documents confirm that OLTs and ONUs can be sold independently based on customer needs, such as upgrading existing infrastructure or deploying specific components in a phased approach. For example, an office might procure an OLT to centralize management while adding ONUs later to expand coverage. This modularity supports tailored solutions, making the statement TRUE.
