SDH MSPP Optical Transport Equipment

SDH MSPP Optical Transport Equipment:DHODT-LMXE
Description

Overview
As a key member of VeeCOM "MetroEdge-Express" SDH/MSPP Product family, DHODT-LMXE is a carrier-class, cost-effective, compact (only 3U high) STM-1/STM-4 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-LMXE Is a card based compact SDH equipment, designed mainly as a gateway node between the core SDH network and a number of remote CPE boxes. It may also be used as a multi service SDH ADM node in a typical ring or mash network. The 3RU high 19 inch wide chassis of the DHODT-LMXE has 19 card positions, with 2 slots for the 1+1 power cards, 1 slot for network management card, 2 slots for network interface unit(NIU) cards, and 14 slots for local interface unit(LIU) cards.
