Description

SDH/MSPP

Introduc e

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.

Features
1. Support 1+1 MSP, SNCP protection
2. Management channel can be DCC bytes or E1 (VC12)
3. Support up to STM-4 rate
4. E1 BERT test is embedded
5. Ethernet service supporting GFP encapsulation, VC12 virtual concatenation (1~63 VC12) and LCAS
6. Large cross-connect matrix capacity is 1134x1134 VC-12s (18x18 VC-4s) and powerful networking ability
7. Inter-working with popular SDH/MSPP products of various vendors
8. Easy commissioning and maintenance
9. High integration, compact design
10. High reliability, low CAPEX and OPEX
