Alcatel-Lucent 3AL92108AB08 MT320N Microwave Transmission Unit

The Alcatel-Lucent 3AL92108AB08 MT320N is a microwave transmission unit engineered for high-capacity wireless backhaul and fronthaul connectivity in mobile network infrastructure and telecommunications transport applications. This module provides point-to-point microwave radio transmission capabilities operating in licensed frequency bands for cellular base station backhaul, enterprise connectivity, and network extension applications where fiber deployment is impractical or cost-prohibitive. The MT320N card implements advanced digital modulation schemes including QPSK, 16QAM, 64QAM, 128QAM, and 256QAM with adaptive modulation coding (AMC) for dynamic optimization of spectral efficiency and link reliability based on real-time channel conditions. The unit features integrated radio frequency (RF) transceiver functionality with typical channel bandwidths ranging from 3.5 MHz to 56 MHz depending on frequency band configuration, delivering aggregate throughput capacities from 100 Mbps to over 1 Gbps. Advanced features include automatic transmit power control (ATPC), adaptive coding and modulation (ACM), hybrid automatic repeat request (HARQ), multi-input multi-output (MIMO) antenna configurations, space-time coding, and interference mitigation techniques for robust operation in challenging propagation environments. The module supports comprehensive Ethernet and TDM interface connectivity including 10/100/1000BASE-T, 10GbE, E1/T1, and STM-1/OC-3 interfaces for flexible integration with existing network infrastructure. Integration with network management systems provides remote configuration, performance monitoring, fault management, and software upgrades through SNMP v3, NETCONF/YANG, and proprietary element management protocols compatible with Alcatel-Lucent's network management platforms. Advanced OAM capabilities include IEEE 802.3ah Ethernet OAM, ITU-T Y.1731 performance monitoring, synchronous Ethernet (SyncE), and IEEE 1588v2 Precision Time Protocol (PTP) for frequency and phase synchronization distribution to remote sites. The unit features redundant power supply options with −48 V DC input, integrated surge protection, lightning arrestors, and comprehensive environmental monitoring including temperature, humidity, and door contact sensors. Outdoor unit (ODU) configurations feature IP66-rated enclosures with integrated antennas or antenna interface connectors, while indoor unit (IDU) variants provide rack-mountable form factors for sheltered installations. Environmental specifications comply with ETSI EN 300 019 Class 3.1 (indoor) and Class 4.1 (outdoor), ETSI EN 302 217 radio equipment standards, and regional spectrum regulations, supporting continuous operation in ambient temperatures from −40 °C to +55 °C for outdoor deployments and 0 °C to +45 °C for indoor installations with relative humidity up to 100% condensing for outdoor variants. The MT320N is validated for deployment in Alcatel-Lucent microwave transport networks and ensures compliance with ETSI EN 301 123, EN 302 217, FCC Part 101, ITU-R F-series recommendations, and 3GPP specifications for microwave backhaul in 2G/3G/4G/5G mobile networks.
