H9MO-LME Compact SDH Multiplexer
Product Overview
H9MO-LME is a member of Huahuan’s Metro-Edge Express SDH/MSPP product family. This family of products is aimed at the access network establishment, providing TDM and Ethernet services to meet the needs of today’s network evolution. Other members in the Metro-Edge Express include H9MO-LMX, H9MO-LM, H9MO-LMFIT,H9MO-LMV, H9MO-LM63, etc.
H9MO-LME adopts combined design, the system board, power board and interface board are mix-assembly. To meet different requirement of service interface type andquantity, different configuration of H9MO-LME are available. H9MO-LME provides 1/2 STM-1 ports, 2/4 Fastethernet ports, 4/8/16 E1 ports, and V.35 port. It is applicable to different network, such as star network, chain network, and ringnetwork, realizing a very flexible networking.
H9MO-LME supports features as follows:
l Support1+1 MSP, SNCP protection
l Managementchannel can be DCC/E1/VC12
l E1 BERTtest is embedded
l Internalclock/external clock/line clock/clock holdover
l Ethernet service supporting GFP encapsulation, VC12 virtual concatenation and LCAS, PVLAN, 802.1Q
H9MO-LMFE supports the following services on different ports:
l STM-1(Single core is available)
l FE(Electrical)
l E1/V.35/E3/DS3
