Cisco 837 ADSL configuration for NTT OCN Flets ADSL service

[jdelrosario]

All,

I have a Cisco 837 ADSL router that I am trying to configure to connect to NTT's OCN Flets ADSL service. I have the PPPoE username and password. What I am missing is the PVC information for and the PPPoE information that I need to have my 837 connect to the NTT DSLAM. I have had some language/translation issues with NTT. I also can't find the information through any documentation that is in English on any of NTT's websites.

Does anyone know the PVC (VPI/VCI) information for NTT's network? I am trying to bypass the NTT ADSL modem that is already connected but I need to know how to configure my Cisco 837 with the right information to connect to the NTT DSLAM.

Any help would be greatly appreciated.

Thanks in advance,

Joe Del Rosario

Hello Joe,

you don't speak Japanese ???

Just kidding...try PVC 0/32 or 0/38, I think I remember seeing 0/32 being in use...

GP,

I took a 3 semesters of Japanese in college 10 years ago but haven't been able to really use it until now!! :-)

What about the authentication method?? It looks like it is PAP/CHAP authentication...

Do I also need to configure the router as a PPPoE client??

Will this also work if I don't have a static IP address and I just use the "ip address negotiated" config in my dialer statement??

Thanks,

Joe

Hello Joe,

the 837 runs with PPPoA I think. You are right, CHAP or PAP are generally used; the IP address can either be 'negotiated', or you could configure 'ip address dhcp'. Have a look at this sample configuration:

hostname adslrouter

enable secret 5 xxxxxxxxxxxxxxxxxxxxxxxxxxxx

no aaa new-model

ip subnet-zero

ip routing

ip ips po max-events 100

no ftp-server write-enable

interface Ethernet0

ip address x.x.40.34 255.255.255.240

no ip route-cache
