4.2 CONFIGURING DIP SWITCH S1
DIP switch S1 is where you configure the VDSL line rate, symmetric or asymmetric, Ethernet full auto negotiation capability (100Base-T full or half duplex, 10Base-T full or half duplex) or limited auto sense (only 100Base-T half duplex, 10Base-T full or half duplex).
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 standard 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 negotia- tion feature is used when an Ethernet device does not comply with IEEE 802.3x (back pressure flow control) at 100M full duplex.
