USRobotics ADSL Ethernet Modem User Guide
The ADSL Ethernet modem provides home connectivity to an ADSL service
provider network over an Asynchronous Transfer Mode (ATM)/ADSL physical
layer. It receives adaptive rates of up to 8Mbps downstream and transmits
This section introduces the system features of the ADSL Ethernet modem.

This ADSL Ethernet modem should be operated in an ambient temperature
environment of 0 to 50 degree C. The Ethernet modem should be stored in
an ambient temperature environment of -10 to 70 degree C and relative
humidity in the range of 10% and 90% non-condensing.
