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).

3. Why the LAN’s and the NIC’s LED both bright, but the configuration interface is

inaccessible?

1) Use the order of ping 192.168.1.1 to check the Accuracy of connection.

2) Check the Accuracy of working NIC.

3) Whatever the setup of the IP address on your computer (if you close the DHCP function,

you can't obtain the IP address automatically, must specify the IP address of your

computer manually).

4) Run the winipcfg order in the windows 95/98(run the ipconfig order in the windows 2000)

to check whether setup the IP address, subnet mask, default gateway by DHCP.

5) Resume the ADSL Modem default configuration if necessary.

4. Have complete all configurations, but can’t dial through computer

1) Check the indicator of ADSL, it should be working in normally.

TD-8840 External ADSL2+ Router User Guide

2) Check the accuracy of parameter of value of VPI/VCI, Encapsulation mode of AAL5 and

so on, whether you need to install the dial software, such as Winpoet, Enternet.

3) This product has the PPP dial procedure inside

software if your protocol is PPPoA or PPPoE, ADSL Modem will connect automatically.

4) You can check whether your ADSL Modem succeeds in connection with PING

command.

, so you will not need to use the dial
