DHODT-LMFIT is a modularized unit with 4 universal slots, supporting different interface cards, such as STM-1 fiber optic cards, E1 card, Ethernet cards(EoS VCAT), and V.35 card. The main board cross-connect capacity is 504?504 VC-12s (8?8 VC-4s), allowing non-blocking adding/dropping services among different interfaces. It supports the hybrid transmission of SDH, PDH, Ethernet and N?64K V.35 services within the same equipment. With the large capacity cross-connect matrix, the DHODT-LMFIT can be configured as ADM, TM, and REG. It is suitable for multiple network topologies such as point-to-point, chain, ring, hub, and mesh networks.
