Appendix A: FAQ  
1. What related parameters are required to acquire ISP when you want to access the  
internet by ADSL2+ Router?  
1) Dial user: Connection protocol, User name, Password, Value of VPI/VCI, Encapsulation  
mode of AAL5 and so on.  
2) Static IP user: Connection protocol, WAN IP Address, Subnet Mask, Gateway, Value of  
VPI/VCI, Encapsulation mode of AAL5 and so on.  
2. About Connection protocol, VCI/VPI, Encapsulation mode of AAL5  
1) This product supports the PPP protocol over ATM (PPPoA)PPP over Ethernet  
(PPPoE)MAC Encapsulation Routing (MER)IP over ATM (IPoA) and Bridging. You  
may be used with any one of the five protocols above. Because the ISP in different areas  
supports different protocol, you must choose the protocol which is supported by your  
ISP.  
2) The VPI is the English abbreviation of the Virtual Path Identifier, the VCI is the English  
abbreviation of the Virtual Channel Identifier, the value of VCI/VPI must be compatible  
with the value that provided by ISP.  
3) Encapsulation mode of AAL5 include: LLC/SNAP and VC_MAX(often using LLC/SNAP).
