Clocking Resources for 2 PRI's Question

[Yort Mantup]

Hello,

I have a 2821 router with a PRI from one carrier plugged into Controller T1 0/0/0, T1 (PtP) in 0/1/1, and a 2nd PRI from a different carrier plugged into Controller T1 0/3/0. 

The 0/3/0 PRI is new and am bringing it up for testing. The service works but I am getting avg 900 slip seconds on it.  Current clocking looks like this:

clock timezone EST -5

clock summer-time EDT recurring

no network-clock-participate slot 1

network-clock-participate wic 0

no network-clock-participate wic 1

network-clock-participate wic 3

network-clock-select 1 T1 0/0/0

I am unsure how to resolve. I do have a NM-HD-2V installed and unused in Slot 1 on the router.  I was thinking of moving the VWIC2 card there along with the new PRI connection in hopes of creating a separate clocking domain, but unsure if that will work.

Looking for some help..

Thanks!

Hi,

Perhaps you could share with us the set up of yor T1 controlers.

Have you set the T1 lines to be line clocked or internal

show controller t1

Also this link may help
