DHODT-LMFIT

DHODT-LMFIT is SDH/MSPP ADM Multiplexer which has four slots for different service cards, like STM-1,E1,V.35 and Etherent...ect.

As a key member of VeeCOM "MetroEdge-Express" SDH/MSPP Product family,DHODT-LMFIT 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.DHODT-LMFIT is a modularized unit with 4 universal slots,supporting different interface cards,such as STM-1 fiber optic card,E1 card,Ethernet card(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.

*4 General slots, supporting a range of interface cards, including SDH, PDH, Ethernet and V.35 cards
*Ethernet service supporting GFP encapsulation, VC12 virtual concatenation (1~63 VC12)
*Large cross-connect matrix capality of 504×504 VC-12s (8×8 VC-4s) and powerful
networking abilit
*LCD display for system configuration and alarm
*Inter-working with popular SDH/MSPP products of  various vendors
*Suitable for 3G access network  transmission
*Easy commissioning and maintenance
*High integration, compact design
*High reliability, low CAPEX and OPEX
