Before You Use
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.
ADSL Router is designed to offer cost-effective high-speed services for home or office users. It
provides a downstream rate of up to 8 Mbps and upstream rate of up to 1 Mbps for ADSL connection,
even offers auto-negotiation capability for different flavors (G.dmt, G.lite, T1.413 Issue 2 and so on)
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 ADSL Router.
