Launch of new Multi Service Access Node by NEC
NEC Corporation in conjunction with NEC Magnus Communications announced the launch of new Multi Service Access Node (MSAN) AM3100 series equipped with VDSL2 interface in compliance with ITU G.993.2 standards. The new VDSL2 standard will further extend the reach of the copper wire to 4 km in comparison to maximum 1km of VDSL1 standard. The new standard offers compatibility with ADSL/ADSL2+ through product’s ADSL fallback function provide an easy migration to VDSL from the existing systems. The new product provides a 24 and 48 bidirectional transmission speed of 100Mbps (30MHz) per port with a uplink connection between telephone exchange equipment and optical fiber network can be either GPON (Gigabit Passive Optical Network) or Gigabit Ethernet. In achieving a reachability of 4km the new AM3100 series features a variety of functions in insuring the transmission quality by reducing noise such as cross talk between lines. These functions are INP (Impulse Noise Protection) Function for error correction caused by sudden impulse noise, Bit Swap Function capable of transmitting information at a different bandwidth to avoid interference, SOS function which will avoid link down by immediately reducing line speed and SRA (Seamless rate adaptation) function for maintaining suitable speed in response to mild noise changes. Furthermore the new AM3100 features DELT (Dual End Line Test) and SELT (Single Line End Test) functions for determining the cause of lower line speeds and downlinks in the event of a malfunction where the equipment can remotely confirm network conditions from the telephone exchange. The shipping of the new AM3100 series will begin in October of 2009.
