Scenario: 2851 ISR with 2 VWIC-2MFT-T1 installed, one in WIC Slot 1 and the other in WIC Slot 2. Controller T1 0/1/0 is a PRI Voice only, 0/1/1 is DS0 CAS. ?network-clock-participate wic 1? and select 0/1/0 first the 0/1/1 second. This is so they can use the DSP resources on the router system board PVDM Slot(s) in this case. I understand relationship between voice T1s and the clocking domain. My question or discussion is when you have a MLPPP bundle on the VWIC-2MFT-T1 in WIC Slot 2, I would have it NOT participate in any ?clocking domain? (ANY TAKERS?) Then, to extend the question a bit more; of the 2 T1s in the bundle one should ?clock source line? and the other internal?
