Cisco 878.....help!!!

[IMW0908]

Hi. We have been using 2 x Cisco 828's on an EPS9 circuit (copper pair on same telephone exchange). One end has blown and we have got hold of 2 x Cisco 878's to replace both ends. There seem to be various differences in how they are configured as the 828 script will not work on the 878. I have resolved some of the issues, but the one section of the script I can't get past is the 'interface ATM0' which goes like this:-

interface atm0
no ip address
no atm ilmi-keepalive
pvc 0/38
encapsulation aal5snap

When I paste this in, it just stops on the first line:- % Invalid input detected at '^' marker. With the ^ under the n of interface. All the Cisco documentation says that this is a normal command yet it will not take it on either box. ATM0 is not listed as an interface when I do a 'show interface' and it is not listed in the initial config wizard either. This is driving me mad....can anyone help???

Yes---try Cisco 837 for the replacement. In fact, I happen to have one I want to get rid of...

Minue, your statement is lacking grammar.


IMW0908,
Check think line to read about the router. It is ISDN compliant, it also says that it can handle and function using ADSL.

http://www.cisco.com/en/US/partner/...0/850/hardware/installation/guide/857hig.html

Also, it may use different syntax, it's why it may not work 100% with your script from the 828. You might need to fully understand what this 878 Router commands, as all Router to some extend have different command usage. I'm not familiar with using this Series router, but anything is possible.


Peace

it says that the 878 can use G.SHDSL. not ADSL.
ADSl-over-POTS routers are 857, and 877.

anyways.. the 878 seems to be the successor to the 828.
as for config...

check this link..
you may need to enter some lines into the router before the atm interface becomes available...

the section that starts with
"controller dsl 0"

Hello CiscoRC
I Did notice after I read burtsbees reply.That's what you get for posting without re-reading what you wrote.
I guess you are in the same boat "Check think line to read about the router" Thanks anyway!
Regards

LOL....Minue....There's a higher percentile typo mistakes on a laptop keyboard then a desktop with a good keyboard. Besides, I was only typing with one arm since I broke my right arm, which is useless.


pslhlpme,

I just figured that it could be coincided with ADSL, didn't realized the rest of the capabilities. Thanks for the link you just provided. I could use some experience with that for testing on Wic-1ADSL cards. Sweet...

Peace

Thanks to everyone for their input. The issue was fixed with the following commands:-

controller dsl 0
mode atm
line-term CO
mode atm
line-mode 2-wire
!
interface atm0
no ip address
no atm ilmi-keepalive
pvc 0/38
encapsulation aal5snap


Once I ran the 'controller dsl 0' line, it all fell into place. Some other subtle differences but this was the killer!!!

 

[CiscoRC]

That's great imw0908, but why use 2 commands that is the same in the same interface?

mode atm

Only need one...but anyhow, you got it working, that's sweet.

[plshlpme]

the "mode atm" command is done at the controller level not the interface level...
as that controller supports different modes.. as soon as the mode atm is entered.. and atm0 interface becomes available.. i dont have the card to see all the modes...

mode protocol

Example:
Router(config)# mode atm
Router(config-controller)#


Specifies the mode of the DSL controller and enters controller configuration mode.

 

[burtsbees]

I think he was just noticing that in the posted config, the command "mode atm" appears twice under the controller config.
