Overview
DHODT-LMFE is a carrier-class, cost-effective, compact (only 1U high), STM-1/STM-4 SDH/MSPP platform that is designed for application in metro and access networks to facilitate the efficient transport of traditional TDM and emerging data traffic for service providers.
DHODT-LMFE 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 mesh network. The 1U high 19" wide chassis of the DHODT-LMFE has 8 slots, with 2 slots for the DC(1+1)/AC power supply, 1 slot for network management card, 1 slots for STM-1/STM-4 uplink, and 4 slots left for services (STM-1, Ethernet, E1, E3/DS3,V.35 Etc.).
Features
1.Support up to STM-4 rate SDH service
2.Support 1+1 MSP, SNCP protection
3.Ethernet service supporting GFP encapsulation, VC12 virtual concatenation (1~63 VC12) and LCAS
4.Management channel can be DCC bytes or E1 (VC12)
5.Inter-working with popular SDH/MSPP products of various vendors
6.Easy commissioning and maintenance
7.High integration, compact design
8.High reliability, low CAPEX and OPEX
