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.

Table 1: S1 Summary

Position	Function		Factory Default
S1-1	Ethernet Auto Sense	OFF	Full Auto Sense capability
S1-2	Line Rate	ON
S1-3	Line Rate	OFF	12.5Mbps Symmetric
S1-4	Line Rate	OFF

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.

S1-2	S1-3	S1-4	Symmetric Line Rate
ON	ON	ON	6.25 Mbps
ON	ON	OFF	9.38 Mbps
