This is the ADSL modem and four-port ethernet switch supplied by Telstra when I signed up with BigPond. Once I worked out that if it sat flat on the desk it would overheat, but stood on its side it stayed cool, it was rock solid.
Amazingly, it ran for four years with a Telstra ADSL1 connection, fromto , then seamlessly worked with ADSL2 when I churned across to Internode. We eventually had to replace it in July 2015 because it was prone to hanging when “too many” wireless devices connected, and its definition of “too many” seemed to be “around about three”. Handed on to another family member it ran for another year before finally dieing when a power surge hit their house.
