Overview
The SAR ADSL Router features multi-mode ADSL technology that provides a downstream rate of up to 8M bps over
existing copper wire lines, which is more than 100 times faster than a traditional 56K analogue modem. And it can be
connected to your PC or LAN through the 10Base-T or 100Base-T Ethernet interface.
It is designed to meet both the needs of single user, and multiple users at small office and home office who want fast
Internet access. A wide variety of features and interoperability offer scalability and flexibility for all the applications
