DHODT-LMC is SDH/MSPP Terminal Multiplexer which can take 16xE1 over STM-1. With another expanding solt for other service card, like 4*E1,V.35 and Etherent...ect.

As a key member of VeeCOM "MetroEdge-Express" SDH/MSPP Product family, DHODT-LMC 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. It can provide 16E1 TDM interfaces and 1 physical slot that can be inserted with 4E1/8E1/2Ethernet/4Etherent/2V.35 service card in only 1U standard 19” box. DHODT-LMC is best suitable for point-to-point network or standard SDH TM node. Working together with other “MetroEdge-Express” family member such as DHODT-LMFIT, it can support various network topologies such as point-to-point, chain, ring, hub, and mesh networks.
