NEC launches New Multi Access Node with the Fastest VDSL2 Interface for Global Market


*** For immediate use August 21, 2009

Tokyo, August 21, 2009 - NEC Corporation and NEC Magnus Communications, Ltd. announced today the international sales launch of a new multi access node with VDSL2 interface. The new product, AM3150R2, is positioned as part of Multi Service Access Node (MSAN) AM3100 Series, providing the latest VDSL2 (Note 1) interface which complies with ITU G.993.2 standards.

In recent years, broadband access lines using ADSL/SHDSL (Note 2) technologies in overseas markets have been expanding, and faster connections that serve larger areas are being required. Furthermore, future demand for VDSL2 is expected to significantly increase due to its maxim transmission distance of 4km, which far exceeds the 1km maximum distance of VDSL1, its compatibility with ADSL/ADSL2+ and the easy migration to VDSL2 from existing systems.

The new product will provide fast broadband access with a transmission speed of 100Mbps and high quality transmission using existing copper wire telephone lines. This will support the creation of more reliable broadband network services for network providers.

Features of the new product are as follows:

  1. 100Mbps bidirectional transmission speed and easy migration from ADSL
    The new product's downlink line, which connects in-house equipment with metal cable, accommodates 24 and 48 VDSL2 port and provides a bidirectional transmission speed of 100Mbps (30MHz). The uplink connection between telephone exchange equipment and optical fiber networks can be either GPON (Gigabit Passive Optical Network) or GbE (Gigbit Ethernet). Moreover, the product's ADSL fallback function accommodates ADSL/ADSL2+ modems, which enables easy migration from existing ADSL service.

  2. A variety of functions to stabilize transmission quality
    The new product features the following functions for reducing noise, such as cross talk, between lines.
    1. INP (Impulse Noise Protection) Function
      Corrects errors caused by sudden impulse noise.
    2. Bit Swap Function
      When interference or obstructive waves appear at a certain bandwidth, this function transmits information at a different bandwidth in order to avoid interference.
    3. SOS Function (Note 3)
      When an error is caused by the sudden appearance of noise, this function will avoid the link down by immediately reducing the line speed.
    4. SRA (Seamless rate adaptation) (Note 3)
      This function maintains suitable speed in response to mild noise changes.

  3. Superior maintenance support function
    The new product has DELT functions (Note 4) and SELT functions (Note 5) which are useful for determining the cause of lower line speeds and downlinks. In the event of a malfunction, it can remotely confirm network conditions from the telephone exhange.

  4. Lower power consumption
    The new product is one of the earliest to be compliant with EU guidelines for the electric consumption of broadband equipment (EU CDC compliance 2009-2010 under 83.6watts with 24 ports).

The new product will start shipping from October, 2009. NEC is planning to offer the product throughout the world targeting Europe, Asia Pacific and Latin America, and aims to ship 60,000 systems over the next three years.

NEC has provided tens of millions of broadband access lines for global carriers with its ADSL AM31 Series and MSAN (GPON/ADSL/VDSL) AM3100 Series in order to facilitate their broadband evolution. NEC has over 7 million lines installed in Japan and has secured top share in the VDSL market.

The new product will be shown in Paris at the Broadband World Forum in September.
