H9MO-LMP30 Compact Hybrid Multiplexer

Product Overview

H9MO-LMP30 is a small optical transmission-access integrated device, whose multiplexing unituses SDH/MSTP technology with 2 STM-1 optical ports. There are 4/8 E1 ports, 4 100Base-Tx Ethernet ports and 30 PCM voice ports on the service side. Voice ports use internal sub-card structure, which can provide different numbers ofvarious service interfaces like FXO/FXS/hotline/magnet/4-wire/2-wire/asynchronous data by configuring/changing different service sub-cards. As a transmission-access integrated device, it can not only be used for simple remote point-to-point fiber connection, but also can form a self-healing ring network or a chain network, or realize complicated cross-network inter connection through STM-1 optical ports and SDH transmission network.

H9MO-LMP30 is a member of Huahuan “Metro-Edge Express”. “Metro-Edge Express” is a multi-services access and SDH transmission platform built on MSTP/SDH technology. It realizes the features of unified TDM and broadband data access,aggregation, switching as well as management. It is designed to meet the demands of applications in traditional telecom services and broadband data services and adapts to the integration trend of voice and data services for MAN and various private networks.
