Cisco 678 help with a local telco

[briangw]

For MntSnow or anyone else.

Thanks to MHoltum for shooting me over here.

I really need some help. Question for all of you DSL gods....

I used to use a 675 with Qwest years ago. Now, I moved out to a small town west of the Twin Cities, MN. The local telco here just got dsl and are selling proprietary external modems for $240.00. In an attempt to get out of this as cheap as possible, I spoke to someone from the telco's help desk and he said that some people in the area got the Cisco 678 to work. A tech came out and installed a separate line for DSL, so I will not be running this through my regular phone line.

The line that we have out here is Bridging mode with DHCP. I also heard that my VCI could eiter be 35 or 90, but 90 does not work. The limit is 63. The telco is not using PPPoE or PPP modes. I have found several places online to assist me in programming. Here is what I have done.


I tried the same thing with the 675 but to no avail. So, I purchased a 678 from Ebay.

I've erased the NVRAM and rebooted.

After enable,

set bridging rfc1483 enable
write
reboot

enable

set client dhcp enable

write

set int wan0-0 disable
write
set int wan0-0 vpi 0
set int wan0-0 vci 35
write (I'm not at my modem, so I either did it here or after the next..)
set int wan0-0 enable
write

reboot

Now, is the wan0-0 the router or the destination connection? If it's not the router, don't I have to tell the router to look for the VCI of 35?

Here is a copy of show NVRAM and show version:

The local telco also gave me a set of addresses for DNS and Gateway that I need to enter into Wndows, but with no WAN light blinking, like it's looking for a connection, I don't think I need that now.

Oh one more thing, this is a local telco, not Qwest which is all over MN. The Internet Help Desk through this telco is not supporting or providing information on any other modem besides the one they are selling. So, that's why I'm posting here. On top of that, they told a neighbor of mine that they haven't been trained well.

Please let me know if I'm missing anything. I'm also wondering if they screwed up the install of the line in my home, or maybe my connection isn't configured on their end.

TIA.

Oh I forgot to mention. They are using dynamic ips.

Welcome to XPC Brian. Which 678 do you have? (make sure it is flashed with the DMT cbos and not the CAP version) If your Telco was running CAP then your old 675 would have worked.

I'm currently at work so I dont have much time but I will take another look at this thread when I get home tonight.

Again Welcome.

Uh oh. I flashed it with Cap, because it said CAP on the underside. Is that bad? Can I flash over it?

[mholtum]

go here http://www.xtremepccentral.com/articles/dsl/ you can DL the DMT CBOS from the CBOS page MntSnow has so graciously hosted for me.

Get this one 678dmt.full.2.4.7 it is the latest. Then follow the directions as to how to reflash with the DMT CBOS. It shouldnt take more than 4-7 minutes..


And WELCOME to XTREMEPCCENTRAL!

Hey, thanks alot. You guys rock!

Good news, the local telco called me back and said they had my VCI set to 93, so they set it to 35. So, I should be getting a link when I get home. Also, I asked them about CAP vs. DMT and they had no idea. Do you think I should still flash it to DMT?

[mholtum]

I would think that since 90% of the newer DSL installations are using a DMT line that there is a pretty good chance that you will be DMT. Give it ago and I am sure it will work. Good Luck

[briangw]

Is that the only difference between the 675 and the 678; that the 675 runs only in CAP mode and the 678 runs in both CAP or DMT?

[Mntsnow]

Correct...The 678 is CAP or DMT capable where as the 675 was CAP only.

If you havent already flashed I would give it a go as CAP but if it still wont go after your ISP changed the VCI then go to DMT

[briangw]

hmmmm. Which could be why the local telco had more people running 678 than 0 persons using a 675. Maybe they are using DMT.

Still, if I could get the 675 to run, I could re-up the 678 to ebay.

I'm in Unix class right now. I'll post here later tonight/tomorrow to let you know.

[Mntsnow]

Yeah with the ISP saying 678 is why I figure they are running DMT but since you do have it already flashed CAP just check before going thru the flash and config process again ;)

Have fun in class and "start listening to the instructor!" (wife is a teacher so I had to say that :D

Hey, hey hey! It's like 200 degrees in the classroom here!

My wife is studying to be a teacher, so she preaches to me about paying attention. Never did it for my undergrad, probably won't for this associates! ;)

[briangw]

Alright! The DMT mode worked.

Now, my next question. I see on your 678 configure page about a Code Red detterent. Does that have any effect of web pages loading? How does it deter Code Red? Also, I did not enable NAT, does that matter?

I didn't even have to enter the DNS/Gateway information that Lakedale provided to me. My next project is hooking the modem up the my wireless router. Do you think I'll need those addresses then?

Now that I know how to do this, I'm going to email your webpage to the local telco, so that if they have any questions, or have people bringing in their own Cisco 678 modems into the neighborhood, they can refer them to your site.

Thanks again!

[Mntsnow]

It wont effect how webpages load up on your computers or how a webserver from your network will react. but it turns off the GUI configuration page of the cisco router which has a known exploit that the code red virus happens to effect (causes your router to become unresponsive and must be power cycled to recover from it). by disabling the GUI and setting the port # for the gui to a different port the codered packets wont kill the router.

Glad your up and running now that you have it flashed DMT :)

When you say GUI, do you mean the HyperTerminal screen? What does the config page look like without the GUI?

[Mntsnow]

No the GUI is a page that when the Web service is enabled you can access functions of the 67x from a browser instead of using Hyperterm

[briangw]

Wow. You learn something new everyday. did not know you can do that.

How do you access that page?

[mholtum]

There isnt a whole lot to do in the GUI interface, not worth bothering with actually..

Glad it is up and running for you!

I just recently obtained the Cisco 678 modem off of eBay and would like to update the firmware to the newest version; however, the Ex. Password was obviously set by the previous owner and I don't know what it is.

Is there a way to reset it and/or erase it so I can access the CBOS prompt?

:confused:

[mholtum]

After you plug everything into the router, unlpug the power and then plug it back in. When the alarm light comes on hit CNTROL + C

then enter these commands
CBOS# es 6
CBOS# rb


This will erase sector 6 and reboot your router..

any suggestions for recovering a 678 that i was given that some id10t failed a flash, not even a "hello" message from it.
