Level 8

I have not done much config with Clocking so I am looking for some guidence. The reason for this is I am seeing a lot of slips....see below.

2821#show invcontrollers e1

E1 0/2/0 is up.

Applique type is Channelized E1 - balanced

Cablelength is Unknown

Description:

No alarms detected.

alarm-trigger is not set

Version info Firmware: 20080918, FPGA: 13, spm_count = 0

Framing is NO-CRC4, Line Code is HDB3, Clock Source is Line.

Data in current interval (25 seconds elapsed):

0 Line Code Violations, 0 Path Code Violations

0 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins

0 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 0 Unavail Secs

Total Data (last 24 hours)

1797 Line Code Violations, 255 Path Code Violations,

4457 Slip Secs, 1 Fr Loss Secs, 4 Line Err Secs, 0 Degraded Mins,

4460 Errored Secs, 0 Bursty Err Secs, 1 Severely Err Secs, 29 Unavail Secs

E1 0/2/1 is up.

Applique type is Channelized E1 - balanced

Cablelength is Unknown

Description:

No alarms detected.

alarm-trigger is not set

Version info Firmware: 20080918, FPGA: 13, spm_count = 0

Framing is CRC4, Line Code is HDB3, Clock Source is Line.

Data in current interval (26 seconds elapsed):

0 Line Code Violations, 0 Path Code Violations

1 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins

1 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 0 Unavail Secs

Total Data (last 24 hours)

148 Line Code Violations, 3436 Path Code Violations,

1747 Errored Secs, 0 Bursty Err Secs, 12 Severely Err Secs, 140 Unavail Secs

Here is the show inv output and what the config is now and what I think I should change.

2821#show inv

Here is the current config......

no ip address

encapsulation hdlc

isdn switch-type primary-net5

isdn incoming-voice voice

isdn bind-l3 ccm-manager

no cdp enable

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

I want to make these changes

network-clock-participate slot 0

network-clock-select 1 E1 0/2/0

and leave the rest as is.

How far off am I or should I do something else?

Thanks,

Mike

These are the commands you need, but taking clock form the voice circuit should be better, as data doesn-t suffer much from slips.

Should I do it for both circuits?

Mike

Are these circuits from different carriers? If so, I'd just set independent clocking on the controllers.

Yes, Different carriers. So I should do this?

Remove this....

network-clock-participate wic 2

add this

network-clock-participate slot 0

network-clock-select 1 E1 0/2/0

network-clock-select 1 E1 0/2/1

Thanks,

Mike

You cannot have multiple sources to same priority. Leave participate for wic and select priority for voice T1.

The int 0/2/1 is just PRI backup the 0/2/0 is Voip and Data. I would leave the network-clock-participate wic 2 ?

and just add...

network-clock-select 1 E1 0/2/0

Thanks

Mike

One or the other as priority 1, and check the results.

Please remember to rate useful posts with the scrollbox below.

Let me re-word this as I am still a little confused. Based on all the information above and where my WIC cards are installed should this be how I configure this...if not please post what I should be doing. Interface 0/2/0 is VoIP and data and the most important circuit, Interface 0/2/1 is backup PRI's provided by a different vendor. With that said here is what I think I should do but please let me know if that is incorrect or what my config should be...

I think I should remove

network-clock-participate wic 2

And then I should add

network-clock-participate slot 0

network-clock-select 1 E1 0/2/0

network-clock-select 2 E1 0/2/1

Or should I do something else?

Thanks,

Mike

I have indicated already and repeatedly the appropriate configuration. That is, 100% correct and verifiable information.

Then, I'm not sure from who and why I got low ratings in this thread. If it is from you Mike, I can only say that is wrong attitude toward me, good luck.

The information you provided has been good. Like I said in the begining I have not done very much configuring with Clocking and I am just trying to confirm what I have learned from you post which have helped me get to where I am. What I am trying to get answered is what you have given me so far which has helped and based on that am I correct in doint this config?

I think I should remove

network-clock-participate wic 2

And then I should add

network-clock-participate slot 0

network-clock-select 1 E1 0/2/0

network-clock-select 2 E1 0/2/1

Or should I do something else?

I was hoping for a yes that looks correct or no you should do this instead. Your posts so far have been helpful and I truly appreceate you help.

Thanks,

Mike

I just checked how the ratings worked because I was in no way deminishing your help. I see with my ratings it will impact your over all rating. I was being too literal in my ratings and should have rated as an overall. I do appolgize for my misundersatnding and your post have helped me alot.

Thanks,

Mike

p.bevilacqua,

I was wondering if you could reply to this so I could mark this as solution recieved. I put the config you listed and all worked great. Thanks for your help and I am sorry for any misunderstandings, you of great help.

Thanks for your help on this. After I finally got it through my thick skull what you were saying I got it. It has been a very busy couple months so I was a little off. Again thanks for your help.

Thanks,

Mike
