You need to know if the router is seeing the ADSL signal. Use the command "sh dsl int atm0" to check. If that's all good then try a ping from the router to some remote IP address.

Chris.

Check your ADSL line connection. I was getting this last year and changing the cable fixed this. Let me know how this goes. I may have some old configs you can look at.

Thank you ChrisAC. I did try to ping a remote ip and did not get an answer, and DNS is not working. I reverted back to the old Westell Modem for now, tomorrow I'm going to attempt this again. I'll let you know how it goes.

In the mean time, can someone explain to me what the command "dialer remote-name redback" means? I have an idea what "dialer remote-name" means, but I'm confused to why so many configurations use the name "redback".

Another question, Should the PAP and CHAP username and passwords be the same one that was issued by our ISP?

One more question: It appears that we have version 12.1. Are there free upgrades that we can get? I notice that some commands do not work that other people have posted on the Internet for this setup.

Thanks in advance...

OK, Here's the deal.

I had the router up, and I turned on the debug dialer command. I am getting the error: cannot place call no dialer string set. Please help!! It shouldn't need a dialer string!! I'll post the config shortly.

I made the changes that KiscoKid suggested with no success. My configuration looks exactly like the one above and I am getting the same errors with the debug dialer turned on. I also tried using the cable that shipped with the router, and that made no difference.

I found this on the Cisco web site: I will try to get a crossover cable made or purchased. It's worth a try.

Any other suggestions would be very helpful. I copied the show interface and show ver commands, but I left the floppy on site. I will try to post them in the morning.

Thanks.

What result do you get from a "sh dsl int atm0"? If it's trained up then it's not a cable problem.

Chris.

When I try to issue the "show dsl ..." command, it says the dsl part is invalid. When I try to ping a remote IP address from the router, it gets no response. When debug dialer is on, it says "cannot place call no dialer string set" each time something like a ping tries to get out of the dsl interface.

Do a "sh ip int brief" and post the results.

I doubt that IOS image supports what you are trying to do. I just hopped into Cisco Software Advisor and to support the features you are intereted in (Dialer Profiles, NAT and PPPoA etc), Cisco is citing a minimum of 12.2(13).

Do you have a Smartnet agreement with Cisco to perform an IOS upgrade?

This indicates there is a problem with the ethernet port...

00:28:14: %PQUICC-1-LOSTCARR: Unit 0, lost carrier. Transceiver problem?
Click to expand...


The ADSL configuration I use:

interface ATM0
no ip address
load-interval 30
no atm ilmi-keepalive
bundle-enable
dsl operating-mode auto
!
interface ATM0.38 point-to-point
pvc 0/38
encapsulation aal5mux ppp dialer
dialer pool-member 1
!
interface Dialer1
ip address negotiated
ip nat outside
encapsulation ppp
dialer pool 1
dialer-group 1
ppp authentication chap pap callin
ppp chap hostname my-account@isp.com
ppp chap password my-password
!
ip route 0.0.0.0 0.0.0.0 Dialer1
!
dialer-list 1 protocol ip permit


I have some ACL's and Firewall features configured but to get the ADSL line up that is all you should need.

The "00:28:14: %PQUICC-1-LOSTCARR: Unit 0, lost carrier. Transceiver problem?" error only occurs if I physically disconnect the dsl line from the cisco. I'm faced with the problem of getting the adsl line to communicate with the ISP. I still get the "cannot place call no dialer string set" error with debug dialer turned on. The ISP is no help, they will only support their own issued modems (and I'm about to purchase one of their modems and a different firewall).

I did try to use the Cisco Quick Start CD that came with the Router. That was able to communicate with the Router, send commands to it, then I lost the connection. The Quick Start program changed the enable secret password and I couldn't find the password in the documentation. With the Quick Start, it only asked for the VPI/VCI numbers and username and password for the DSL. It configured the Router IP address to 10.0.0.1. I just could not communicate with it after that. I had to reset the password and try again with the command line. I gave up on using that program.

I'm at the end of the line, I'm thinking about selling the thing on ebay.

We do not have a Smartnet agreement with Cisco and we do not intend to purchase one (it would be cheaper to get an ISP issued modem and a different hardware firewall).

Before I do that, I would like to give this another try. I plan to try again on Tuesday.

I'm still open for more suggesions.

Thanks in advance.

I think that without an IOS upgrade you're not going to get this working.

I have purchased a smartnet agreement. I am going to attempt to upgrade the IOS after I get the agreement. I have never upgraded a cisco router, and any suggestions would be great. I will keep posted on how that goes and I'll let everyone know when I get the router working.

Thank you
