DSLAMiin

DSLAMiin is a modular, scalable digital subscriber line access multiplexer (DSLAM) platform intended to aggregate multiple subscriber copper loops into a broadband access network. It supports DSL technologies such as ADSL2+, VDSL2, and vectoring, and is suitable for deployment in street cabinets, remote cabinets, or central offices.

Architecture: A DSLAMiin comprises a chassis, line cards with DSL physical interfaces, a backplane, uplink ports (Ethernet or fiber), and redundant power supplies. It scales by adding line cards to increase port density and may include integrated routing, switching, and service-delivery features. The device interconnects with the core network via high-capacity uplinks and terminates copper loops from customers.

Management and services: It offers remote management through SNMP and vendor dashboards, and may support NETCONF. Feature sets typically include QoS, VLAN tagging (802.1Q), PPPoE or IPoE authentication, and subscriber accounting via RADIUS or Diameter. Monitoring, fault isolation, and vectoring/bonding options are commonly supported where hardware permits.

Deployment and operation: In practice, a DSLAMiin aggregates DSL connections within a local area and forwards traffic to a BRAS or IP/MPLS core. It is designed for high availability with hot-swappable line cards, redundant power, and NEBS-grade variants in certain deployments. Operators use DSLAMiin platforms to deliver broadband services over existing copper infrastructure.

Variants and standards: DSLAMiin platforms typically align with ITU-T DSL standards for ADSL2+ and VDSL2 (for example G.992.x and G.993.x). Features such as vectoring, bonding, QoS, VLANs, and scalable management are commonly supported depending on the model and vendor.
