Aztech ADSL Ethernet Router (DSL 900ER)
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.
