The Aztech DSL900E(R) is a Controller-based External ADSL WAN bridged modem/router with an Ethernet Interface. It uses ST Microelectronics' Centaur solution for the ADSL WAN connectivity that fully complies to ANSI T1.413 Issue 2, ITU-T G.992.1 (G.dmt) and G.992.2 (G.lite) ADSL standard. It supports Full-Rate ADSL transmission at up to 8Mbps downstream and up to 640Kbps upstream.

Targetted at SOHO environment, DSL Telco/Service Providers can provide Business DSL services to a multi-user environment with support both Static and Dynamic IP Routing, Network Address Translation and Dynamic Host Configuration Protocol Server.
