Link up time between local and remote G.SHDSL network extenders can vary from one to five minutes
depending on the quality, gauge and distance of the copper cable pair being used. If the cable distance is
greater than a particular bandwidth will support, the units may not link up or, if they do achieve link, traffic
quality may be affected (e.g., packets may be dropped).
1.5 Connect the Ethernet Line
N
OTE
If a G.SHDSL connection has not yet been made, the Ethernet link will remain disabled (as indicated
by solid illumination of the Ethernet 100, Act and Lnk LEDs) until at least one of the four G.SHDSL
links has been established.
1.5.1 Duplex
Mode
The 10/100 Ethernet port auto-negotiates speed and duplex mode in accordance with the remote
equipment to which it's connected; Ethernet speed and duplex mode configurations cannot be hard set
on the SPEED-DSL 9.2. For the best connection results, the remote device (PC, hub, switch, etc.) 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.
1.5.1.1 Half Duplex
Receive and transmit functions are mutually exclusive; data transmission occurs in only one
direction at a time. Packet collisions are not unusual.
1.5.1.2 Full Duplex
Receive and transmit functions occur simultaneously, effectively doubling aggregate bandwidth and
preventing packet collisions.
