[Tony Varriale]

Please do a "show network-clock"

I'm going to guess you show the backplane and that's it?

> Scenario:
> 
> Cisco 2821 router running 12.4(18)
> VWIC2-2MFT-T1/E1    terminating E-1 connections from two ISPs.
> 
> Both are configured clock source line.
> 
> Both providers are sourcing clock, but apparently not in sync with each 
> other.
> 
> Second E-1 on the WIC shows slips.  It appears that "clock source line" 
> doesn't do what it should, or somehow the first E-1 is clocking both 
> circuits.  Physically disconnecting the first E-1 fixes the slips on the 
> second.

> Bug?  Misconfiguration?  Hardware limitation?
