uBR10012 upstream lock problem 24x8

Hi guys,
I need help with cisco 10k, I cant lock upstream signal and I don't know why. I tried without extermal time creator...DTI, downstream ok. My config..

When running primary-enabled

When running primary-enabled modular-cable downstreams :
* you must connect CMTS and EdgeQAM to a DTI server
* you must add "cable clock dti" to your running config

For 24x8 bonding, you must run at least IOS version 12.2(33)SCH2, and have at least PRE4

Not too sure about your "cable upstream ranging-init-technique 3". I would remove this at least while trying to resolve your registration issues.

Beware your upstream power levels. As you add more channels to the US bonding group, the CM is allowed less transmit power per channel.

I see you are using Annex A downstream, and you have upstream frequencies above 42MHz. So just to check the obvious, your plant has a 65MHz or 85MHz split, and your CMs are EuroDOCSIS?

Other than that, your configs look reasonable

Hi, thanks

agree, I have DTI server....TimeCreator 1000, but I dont know how it should be set-up. I find how to login, but no more.
cable clock DTI - added, cable upstream ranging-init-technique 3 - removed, IOS - OK, EuroDocsis.
Thanks.

Why 8x 3.2MHz?

8x 3.2MHz looks insane to me. Why not simply bonding 4x 6.4MHz? Also don't forget to enable the equalization coefficient...

Also it seems you configured upstream 0 to 7 on connector 0.
To my knowledge MC20x20 supports max. 2 Channels per connector and MC3G60 supports max. 6 Channels per connector.
Your config shows eight channels on connector 0

Hi, thanks, I use MC3GX60V, also I need 8 x bounding group upstream for test...required by client.

Time Creator

Hi, issue resolved, I added time creator, some changes in config, now everything works fine.

Thanks&
