   General use for Amazon-SE:
   The Amazon-SE offers cost-effective ADSL2/2+ Modem/Router solutions. Amazon-SE (PSB
   50601) comes with a variety of hardware interfaces and it is assembled in a LQFP package
   which enables a system board to be built on a 2-layer only PCB. Together with complete
   software packages, the Amazon-SE system solution supports data, voice and video
   equipment to access the internet at greatest speed and convenience. Focused on cost
   sensitive market segment, Amazon-SE is an ideal choice for broadband users from residential
   to SOHO (Small Office/Home Office) environments.
