Lucent Technologies Enhances DSL Capabilities with ADSL-Over-ISDN Module

Strategic Insights -

Lucent Technologies, a leader in the development of digital subscriber line (DSL) technologies, has announced a breakthrough enhancement to its Stinger access concentrator. The new ADSL-over-ISDN interface module is designed to enable service providers to deliver high-speed, integrated ADSL services over existing ISDN infrastructure. This innovative solution will allow service providers to offer end-users voice and data services, as well as faster Internet access, simultaneously over existing ISDN lines at speeds up to 8 Mbps.

Key Takeaways:

  • The ADSL-over-ISDN module is a significant enhancement to Lucent's Stinger access concentrator, enabling service providers to deliver high-speed ADSL services over existing ISDN infrastructure.
  • The module supports up to 24 ports, with a total of 336 ports per Stinger chassis, and uses the ITU standard G.992.1 Annex B for ADSL on ISDN lines.
  • The module will be available by the end of this year and is expected to make Stinger the platform of choice for service providers that want to offer high-speed ADSL services over POTS and ISDN lines.
  • Stinger is the first integrated DSL platform to incorporate a high-speed ATM switching fabric, giving service providers end-to-end QoS capabilities, bandwidth management, and priority policing capabilities.
  • The product offers nearly three times the port density of competing products in a smaller footprint and supports up to 672 ports per chassis and 2016 ports per rack.
  • Stinger provides support for all versions of DSL, including SDSL, ADSL (full-rate and G.Lite), IDSL, and HDSL2, allowing service providers to deliver a wide range of applications from a single platform.
  • The product also delivers greater flexibility with support for both ATM and Frame Relay from customer premises to central office, offering service providers the choice of provisioning either an ATM or Frame-based access network.
  • Stinger joins Lucent's MultiDSL portfolio, which consists of an end-to-end turnkey solution from customer-premise equipment (CPE) to access concentrators to circuit termination in the backbone.

Statistics:

  • The ADSL-over-ISDN module supports up to 24 ports, with a total of 336 ports per Stinger chassis.
  • The module uses the ITU standard G.992.1 Annex B for ADSL on ISDN lines.
  • Stinger offers nearly three times the port density of competing products in a smaller footprint.
  • The product supports up to 672 ports per chassis and 2016 ports per rack.
