Connecting the Ethernet Line
If a G.SHDSL connection has not yet been made, the Ethernet link will remain disabled (as
indicated by no illumination of the Ethernet 100, Act and Lnk LEDs) until at least one of the four
G.SHDSL links has been established.
Duplex Mode
The 10/100 Ethernet port auto-negotiates speed and duplex mode in accordance with the remote
equipment to which it is connected; Ethernet speed and duplex mode configurations cannot be
hard set on the SNE2040G. For the best connection results, the remote device (PC, hub, or
switch) should be set to auto-negotiate speed and duplex mode as well. If the remote device
cannot be configured to auto-negotiate, speed may be hard set at either 10 Mbps or 100 Mbps but
duplex mode must be hard set to Half Duplex; a 10/100 Ethernet connection will not operate
properly if the remote device is hard set to Full Duplex.
z Half Duplex – Receive and transmit functions are mutually exclusive; data transmission
occurs in only one direction at a time. Packet collisions are not unusual.
z Full Duplex – Receive and transmit functions occur simultaneously, effectively doubling
aggregate bandwidth and preventing packet collisions.
