4.2 CONFIGURING DIP SWITCH S1
DIP switch S1 is where you configure the VDSL line rate, symmetric or
asymmetric, Ethernet full auto sense capability (100BaseT full or half
duplex, 10BaseT full or half duplex) or limited auto sense (only
100BaseT half duplex, 10BaseT full or half duplex). Table 1 summarizes
default positions of DIP switches S1-1 through S1-4. Detailed descrip-
tions of each switch follow the table.
Switch S1-1: Ethernet Auto Sense
Use switch S1-1 to configure the unit for full auto sense capability or lim-
ited auto sense capability. Full Auto sense capability consists of stan-
dard Ethernet Auto sensing (100BaseT full duplex, 100BaseT half
duplex, 10BaseT full duplex, and 10BaseT half duplex). Limited Auto
sensing capability consists on only auto sensing for 100BaseT half
duplex, 10BaseT full duplex, and 10BaseT half duplex. The limited auto
sensing feature is used when an Ethernet device does not comply with
IEEE 802.3x (back pressure flow control) at 100M full duplex.
Switches S1-2 and S1-4: Data Rate
Use switches S1-2 and S1-4 to configure the VDSL line rates.
