BX1000 – Sonet/SDH Optical Access Router

The BX1000, AimValley’s next-generation SDH ADM, enables true multi-service provisioning and serves the requirements of tomorrow’s converged networks. The cost-effective add/drop multiplexer integrates voice, leased line and packet services on a compact platform. All applications are served by a common set of cards for two system configurations; designed for customer premises and access as well as metro aggregation networks.


  • SDH interfaces: STM-1, STM-4 and STM-16 supporting multiple ring closure
  • Access interfaces: E1, DS1, E3, DS3, SDSL, Fast Ethernet and Gigabit Ethernet
  • Non-blocking cross connect at all VCn levels
  • Standards compliant Ethernet mapping via GFP and Virtual Concatenation; Ethernet private line or Multipoint Virtual LAN service with bandwidth sharing
  • High-density interface cards with hot-pluggable SFP modules for optical and electrical interfaces
  • System configurations with 2 or 6 slots, allowing optimal choice per application, size or capacity needs
  • Vertical and horizontal rack mount configurations
  • Low power, small size
  • Very low-cost start-up configuration

Capex & Opex Reduction

The BX1000 is highly scalable: the operator can start with a basic single card configuration at lowest price and cost-effectively upgrade the system as service demand requires more capacity or more interfaces. In addition, the operator can choose from two configurations to match system capacity and price level with quality of service demand.

Capex and Opex reductions are the main benefits of the BX1000:

  • Highly integrated architecture with all system core, line and control functions combined on a single card, optionally protected; high-density tributary cards with up to 63 interfaces each
  • Convergence of data and voice combined with high integration density significantly reduces the amount of equipment; this results in lower investment, installation, operational and maintenance costs
  • Optimal bandwidth utilization and flexibility is guaranteed by data mapping using GFP, Virtual Concatenation and LCAS. Bandwidth is allocated according service demand with a granularity down to 100 kbit/s
  • The integrated data switch provides local switching and oversubscription to best utilize the available network capacity; while retaining full customer isolation and enforcing individual service level agreements
  • Hot-pluggable small form factor pluggable (SFP) modules for STM-N optical and electrical as well as Gigabit Ethernet interfaces reduce the amount of spare parts and allow for step by step interface deployment

Integration in existing networks

The BX1000 protects the investments made in the installed SDH network and improves the operator’s TDM services and revenue through its higher integration and lower cost solution. In addition, the system supports effective Ethernet transport over the existing network without the need for costly deployment of an overlay network.

Management of the BX1000 is easily integrated in an existing network management solution. The system provides an Ethernet management port for on-site craft maintenance. Remote management is via DCC channels or in-band via a 2 Mbit/s payload channel. The BX1000 provides SNMP management as well as web-browser based provisioning; system management via the 7-layer OSI G.773 protocol stack can be supported as well.
