H9MO-LMXE+.V2 Integrated Access Multiplexer
Product Overview
H9MO-LMXE+.V2, which was developed by Huahuan, provides various features and applies todifferent networking, meeting customers' requirements. The H9MO-LMXE+.V2 is an integrated access multiplexer of Huawei. Traditional pulse code modulation(PCM) devices need to work with optical transmission devices. Based on the MSTP architecture, the H9MO-LMXE+.V2 integrates SDH transmission and PCM services.Traditional networking must use PCM and SDH devices independently.
H9MO-LMXE+.V2, which is deployed between the backbone network and access network,provides various service ports and large-capacity transmission capabilities.With the small size, lower power consumption, high reliability, H9MO-LMXE+.V2 is easy to maintain and manage, which saves space in the equipment room and minimizes the CAPEX and OPEX.
H9MO-LMXE+.V2 is widely used in power, oil, and transportation industries, and for municipal NM and water resources monitoring. It supports transmission of monitoring, remote control, and alarm data signals, and provides dispatching phone and administrative phone services on the transport network.
H9MO-LMXE+.V2 supports the following transmission modes:
● Optical port transmission with the rate of STM-1/STM-4/STM-16
● E1 port transmission
H9MO-LMXE+.V2 supports the following services on different ports:
● PCM voice services on FXO, FXS, hotline, magnet, 2/4-wire audio ports and EM
● Low-speed synchronous data services (N x 64 kbit/s V.35, X.21, and C37.94data), asynchronous data services (RS-232/V.24/V.28, RS-422, and RS-485/V.11), 64kbit/s G.703 co-directional data/C37.94 teleprotection interface, Dry contact interface, High voltage protection interface etc.
● PDH services through the E1, E3/DS3 ports.
● Ethernet services including switching, channel Ethernet services and FE/GEservices.
● Support Layer-3 routingcard, RS-232 conference, 2-wire/4-wire audio voice conference, analog telephone conference.
