Description
As a key member of AD-net SDH/MSPP Product family, AN-miniSDH is a carrier-class, cost-effective, compact (only 1U high) SDH/MSPP platform that is designed for applications in metro and access networks to facilitate the efficient transport of traditional TDM and emerging data traffic for service providers.
AN-miniSDH is a modularized unit with 4 universal slots, supporting different interface cards, such as STM-1 fiber optic cards, E1 cards, 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 AN-miniSDH 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
