 SDH communication equipment

Overview:

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

As a key member of VeeCOM "Metro Edge-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.

Features:

*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 capacity of 504×504 VC-12s (8×8 VC-4s) and powerful networking ability

*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
