    Aggregation Switches: ML2300

    The Actelis® ML2300 is a compact, next-generation Ethernet aggregation platform that delivers high-speed Ethernet services.

    With Actelis’ best-in-class Ethernet over copper solutions, incorporating EFMplus™ and DRB technologies, the ML2300 delivers unprecedented Rate, Reach and Reliability over existing copper facilities, enabling wide-scale deployment of Ethernet services and infrastructure. The ML2300 is available with front and rear access options and installs within minutes, enabling immediate deployment of broadband services. The ML2300 offers a density of up to 64 ports per Rack unit (RU). The ML2300 is interoperable with any standard Ethernet switch or router and aligned with Metro Ethernet Forum (MEF) recommendations, enabling Actelis systems to seamlessly integrate into carrier Ethernet networks.

    Architecturally, the ML2300 platform serves as a Central Office (CO) aggregator in a Point-to-Multipoint topology connecting to multiple ML600 (copper) and ML500 (fiber) Ethernet Access Devices (EADs). For copper deployments, each ML600 EAD is connected to the ML2300 via a High-Speed Link (HSL) comprising 1-8 bonded-copper pairs and offering up to 100Mbps per HSL. A number of ML2300 systems can be stacked in a Star or Ring topology, providing flexible topology layouts and higher port density per uplink. To meet higher bandwidth and/or reach requirements, the Actelis ML230 can be used as an EAD bonding up to 32 pairs per HSL, offering more than 400Mbps per HSL. The ML2300 HSLs can be used both for aggregation and service distribution.

    The ML2300 has two Service Dispatcher Unit (SDU) slots and four Multiport Line Unit (MLU) slots, allowing for incremental service growth, equipment redundancy, MLP (Modem Line Port) redundancy and flexible modem allocation (any modem to any HSL) using pluggable cards. A variety of SDU and MLU cards exist, supporting different numbers of Ethernet and modem ports per chassis. The MLU-32EF, MLU-32ER, MLU-32DF and MLU-32DR line units offer 32 G.SHDSL.bis modems per card and up to 128 modems per shelf. The MLU-64DR and MLU-64DF line units offer superior density of 64 G.SHDSL ports per card and up to 256 ports per ML2300. When equipped with MLU-64DR/DF or MLU-32DR/DF, the ML2300 offers significantly increased performance over bonded copper by utilizing Actelis’ DRB technology.

    The SDU-440/450 linecard series offer advanced Ethernet switching capability as well as multiple uplinks, providing flexible integration into Ethernet and SONET/SDH networks. The ML2300’s Small Form-factor Pluggable (SFP) ports accept standard 100Base-FX, 1000Base-FX, 2500BaseFX, 1000Base-T and T3/E3 modules. Digital Diagnostics Monitoring (DDM) capabilities are supported for enhanced diagnostic and troubleshooting.

    The ML2300 can dramatically increase reach by utilizing Actelis’ XR239 G.SHDSL EFM repeaters and Actelis’ PFU-8x units for repeaters remote powering. The ML2300 can support up to 8 hops (9 segments), with each XR239 supporting 2 copper pairs.

    The ML2300 supports current and evolving MEF service requirements, supporting 2000 EVC flows meters, policing and shapers. Additionally, the ML2300 provides 802.1q VLAN-aware wire-speed bridging, optimizes multicast switching by IGMP v1/v2 snooping, performs double tagging (VLAN stacking) for end-user VLAN transparency, applies 802.1p COS classification and marking, as well as supports per port egress rate limiting. Service resiliency can be assured using Ethernet Ring Protection Switching (ERPS) (G.8032), offering sub-50ms protection switching. In addition, RSTP/STP, Automatic Protection Switch (APS) and Link Aggregation (LAG) protocols are supported on all Ethernet ports.

    The ML2300 provides enhanced troubleshooting and OAM capabilities. The ML2300 offers proactive and reactive tools for dynamic troubleshooting and monitoring capabilities. Advanced Carrier-class EFM OAM, including 802.3ah, CFM (802.1ag) and Y.1731 (ITU), are incorporated, offering physical link, service level end-to-end advanced troubleshooting, as well as performance and Service Level Agreement (SLA) monitoring mechanisms. In addition, the ML2300 supports bandwidth utilization monitoring per port and EVC as well as Ethernet frames triggering. Time-Domain Reflectometer (TDR) capability, integrated as part of the ML2300 along with external Metallic Loop Test (MLT) connectivity, enables an effective troubleshooting tool to locate most DSL-affecting copper problems. The information gathered includes accurate end-to-end loop length measurement, as well as identification of various fault types impacting signal continuity between loop spans.

    The ML2300 can be managed In-Band and Out-of-Band by Actelis’ MetaASSIST™ View graphical craft application and via Actelis’ multiplatform Element Management System, MetaASSIST EMS. The management protocols include SNMP using standard MIBs, de facto standard CLI, and standard TL1 command line interface for seamless integration with third-party Network Management Systems (NMS).
