Enabling Fiber to the Node

Digital subscriber line access multiplexers (DSLAMs) are helping transform traditional POTS networks into a new generation of high-speed networks capable of delivering a range of revenue-generating triple and quadruple-play services. By leveraging the existing copper infrastructure, these pieces of central office equipment enable low-cost deployment of video on demand, high-speed Internet access and low-cost voice over IP services.

To keep pace with consumer demand for network access, the next-generation of DSLAM platforms must provide higher port density, lower per port cost and improved energy efficiency. And they must operate in concert with passive optical network technologies including PON to extend cost-effective access in mixed-use fiber-to-the-node (FTTN) implementations.

Must-have features include:

  • Support for multiple profiles – including 17, 12 and 8 MHz
  • Support for multiple xDSL implementation standards — VDSL2, VDSL, ADSL2+, ADSL2 and ADSL
  • Quality of Service – queuing and scheduling
  • Robustness – impulse noise protection, seamless dynamic rate repartitioning for bandwidth reallocation, dual latency and dual interleaving
  • Performance – up to 100 Mbps symmetrical bandwidth
  • Port density – up to 48+ port line cards supported
  • Scalable software architecture – easily upgraded to support new features and configurations

Ikanos offers a family of integrated central office semiconductors and software that address the needs of DSLAM customer requirements and enable the development of high-performance, triple and quadruple-play offerings.
