Preface
Thank you for choosing the Asymmetric Digital Subscriber Line (ADSL) Router. With the
asymmetric technology, this device runs over standard copper phone lines. In addition, ADSL allows
you to have both voice and data services in use simultaneously all over one phone line.
SL2-141/SL2-141-I Wireless ADSL2+ Router is a DSL broadband access device which allows
ADSL connectivity while providing 802.11g wireless LAN capabilities for home or office users. It
supports ADSL2/ADSL2+ and is backward compatible to ADSL, even offers auto-negotiation
capability for different flavors (G.dmt, G.lite, or T1.413 Issue 2) according to central office
DSLAM’s settings (Digital Subscriber Line Access Multiplexer). Also the feature-rich routing
functions are seamlessly integrated to ADSL service for existing corporate or home users. Now users
can enjoy various bandwidth-consuming applications via SL2-141/SL2-141-I Wireless ADSL2+
Router.
