H9MO-LMFIT Compact SDH Multiplexer

Product Overview

H9MO-LMFIT as a key member of Huahuan “MetroEdge-Express” SDH/MSPP Product family,H9MO-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 trafficfor service providers.

H9MO-LMFIT is a modularized unit with 4 universal slots, supporting different interfacecards, 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 (8×8VC-4s), allowing non-blocking adding/dropping services among different interfaces. It supports the hybrid transmission of SDH, PDH, and Ethernet and N*64K V.35 services within the same equipment. It also supports 2048*2048 64K(full 64E1) cross-connect capacity using FDXC64 card. With the large capacity cross-connect matrix, the H9MO-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.

Main features as follows:

l   Support 1+1 MSP, SNCP protection

l   Management channel can be DCC/E1/VC12

l   Internal clock/external clock/line clock/clock holdover

l   Ethernet service supporting GFP encapsulation, VC12 virtual concatenation and LCAS, PVLAN, 802.1Q VLAN

H9MO-LMFE supports the following services on different ports:

l  STM-1(Single core is available)

l  FE(Electrical and Optical)

l  E1/V.35
